Oh, I am going to murder so many robots. Click to listen — The Medic after studying some strategies

”

This article details strategy for the Mann vs. Machine game mode.

General Strategy

• Teamwork is more vital than ever. Make sure to communicate at all times.
• The robots don't drop ammo, so take note of ammo placements and consider getting Engineers to place Dispensers at choke points. Slain players still drop their weapons, however, so if your teammate is unfortunate enough to die, grab their ammo if you need any. You may also refill your weapons with ammo in the form of destroyed Engineer buildings, most commonly if a Sentry Buster has just detonated beside them.
• Robots rarely, if ever, jump. Maps are designed so most places can be reached without jumping. If you need to evade pursuing robots, look for something to jump on or over.
  • If there are Spies on the field, you can also quickly show teammates that you are not a disguised enemy Spy by hopping, or firing your weapon.
• Tanks do not harm players, so feel free to get as close as you want when trying to destroy one. Be careful when attacking a tank in a confined space however, because a turning tank may crush players against walls and kill them instantly.
• Try to collect all the money the robots leave behind. The Administrator gives the players a bonus $100 if the team takes them all, and more money means more upgrades.
• If there is a Spy robot and a Tank on the field at the same time, you can evade the Spy by standing on the Tank.
• Spy robots often reveal their location by chuckling, even when disguised. Listen carefully for them when you can't afford to look around the field.
• Before entering your first wave of the mission, consider your class and its weapons carefully. Once that money is invested into the class and the wave is won, you cannot get a refund on previous upgrades. This makes team composition even more vital as you'll have less power if you switch classes in the middle of the mission. Agree on which classes and weapons everyone should have before starting.
• If your team keeps failing at a wave, upgrade different things before the wave begins, e.g. if a Tank always deploys its bomb before you can destroy it, invest in Critical Hit Boost Canteens. If that still doesn't work, ask your team if you want to restart the mission.
• Über Medic Robots always spawn with a full ÜberCharge meter and will use it if they even take the slightest bit of damage. Either make them waste their Über early before they reach your ally's choke point or destroy them with a single blow.
• Before each wave, before the robots are released, there will be floating holographic arrows that show the path the bomb robot will take. Use these to plan a defense. Engineers should especially take heed of these arrows to set up more effective Sentry Guns, and Demomen should leave their sticky traps where the robots will go. Most of the team should focus firepower there and locate chokepoints so you can easily pin down enemies.
  • Remember that these arrows disappear when the robots appear, and that the arrow locations change between waves. If your team fails to defend against a wave, the path may change, too. Before a wave, if a teleporter isn't present to take you to the front lines, consider following the path for practice.
  • Enemies may stray from the path to chase down a player, so try to kill them before they take another route to the base.
  • If the robot carrying the bomb is moved off this path and then killed, the robots will go for the bomb and then take the shortest route to the hatch. Keep this in mind.
• Robots cannot attack or be harmed until they touch the field, so Demomen and Soldiers have time to leave explosives in the enemies' path.
  • Don't be too eager. If you blast robots too early, you'll only scatter them, making them more difficult to destroy, and the money will scatter and be harder to collect.
• Bomb carriers taunt to receive their buff, and robots surrounding them stop to wait so they can travel together. Robots may also taunt after killing a player, even while being attacked. Use this time to destroy the robots.
• Try not to find yourself on an open area when the Sniper Robots arrive; you will only make yourself an easy target for their shots.
• Sometimes upgrading your resistance can be more important than upgrading your equipment. In some cases it gives you a higher chance of survival.
• Try to make your team's class composition balanced. Having 2 or more of the same class is usually pointless; for example: 2-3 Scouts.
  • If there are 2 or more players playing as the same class on the team, try to maximize their role together. (2 Heavies on defense, 2 Scouts collecting all credits, 2 Demomen for Quick traps, etc).
• At the end of a wave, instead of running back to the upgrade station, switch classes and switch back for a fast way to come back to upgrade station between waves.
• Classes that have low Primary weapon ammo clip (Soldier, Demoman, etc) might want to invest in an Ammo Clip upgrade.

Class-specific strategy

 Scout

• Due to the defensive nature of this mode, the Scout is at a disadvantage, with low health and short-range weaponry. To counter this, he's given a wider money gathering radius, gets health from gathering money, and respawns much quicker than the other classes.
• Scouts should always be aware of the positions and amounts of cash around them. In some cases, it is wiser to charge enemies head on to collect a large sum of cash behind them, supplying you with more than enough health to either deal with the foes or flee.
• The Scout's short respawn time means he's allowed to take risks. Even if it means getting killed, Scouts should rush to collect the money close to expiring.
• Consider upgrading resistances and move speed and focusing on collecting all of the money drops. Cash collection becomes a breeze, cash drops will keep you full to the brim with health which, coupled with your resistances will make you very tough and enemies will waste much of their firepower aiming at you. In a pinch you can outrun anything that's too big for you.
  • Consider also upgrading your jump height, the full upgrade is quite cheap and will allow you to get up onto the higher decks and out of pits without wasting time using the stairs. This will improve your money grabbing ability.
• A Scout investing on multiple resistance upgrades along with the health boost of cash drops can prove to be a great distraction tool, allowing allies, even Spies, to get more free hits.
• The Scout gets more mileage from the jump height upgrade thanks to his Double Jump. Consider investing a point into upgrading jump height, which makes reaching higher ground or jumping away from swarming robots easier.
• The Scout's role is not restricted to money gathering; with piercing upgrades his primary weapons can take out whole crowds of enemies at close range. Each of the Scout's primary weapons has its uses: the Scattergun has the bigger clip, the Force-A-Nature has knockback, the Soda Popper can build up periods of mini-crits, and the Shortstop and Baby Face's Blaster can allow you to do damage from a safer distance.
• Once upgraded, a hit from the Sandman's ball marks a robot for death like the Fan of War, meaning the robot will take mini-crits from your friends' weapons. Both the Sandman and the Wrap Assassin can also be upgraded so that more balls can be hit, meaning more targets being affected. Keep in mind, however, that the Sandman reduces the Scout's health to 110, making him able to take less hits before dying.
  • The upgrade also affects melee attacks from the Sandman itself. It can be used if you run out of balls to throw.
• The Fan O'War can be very effective if you manage to mark a Giant robot for Death, since a very large amount of firepower is needed to destroy them.
• Mad Milk is a great assisting tool, as anyone who hits a doused robot gets a health boost, and upgraded Mad Milk slows down wet robots, making them easier to hit. It can also be used to help root out Spy bots.
• Using Bonk! Atomic Punch can allow you to serve as a distraction for giant bots, as well as grab credits without fear of being blasted to oblivion.
  • Übercharge Canteens can work in a similar way, providing invulnerability to collect cash in dangerous areas. However, you can still attack with an Übercharge, allowing you to mark dangerous targets with the Fan O'War or blast them with your primary weapon a few times at point blank range.
• As a Scout, you are usually the only one that can catch up to Scout Robots early in the mission. Since early waves tend to have copious amount of Scout Robots, be alert if any of them are carrying the bomb and are close to the hatch.
• If you are near a tank when it is destroyed, you can collect a good deal of the money dropped for an incredible health boost.
• A good Scout knows when to collect money and when to give support to their allies. Prioritize your objectives quickly before it's too late!
• Despite not being listed, Scouts can use Buyback. Use Buybacks on desperate situations.

Example Combinations
Combo			Usage
or Force-A-Nature or Scattergun	Mad Milk	Sandman	A loadout for a more offensive-support Scout in Mann vs. Machine mode. The Force-A-Nature can be crucial for moments when the bomb-carrier is close to a bottomless pit in Coal Town or when it is about to take the bomb into the hatch. Alternatively, on maps with more cover and opportunities to flank the robots (Mannworks and Bigrock), the stock Scattergun can be useful for strong surprise attacks. Mad Milk should be upgraded to slow robots, as that not only makes fighting giants easier but also gives support to your team that could not be done nearly as efficiently. The Sandman not only stuns robots, but can mark them for death if given the right upgrade. Using both Mad Milk and the Sandman on a giant or Sentry Buster immediately makes it easier for your team finish them off. Upgrades should primarily focus on increasing your offensive potential, such as large clip size, reloading speeds, damage bonus, and firing rate for your primary. Maximum recharge rate for Mad Milk and Sandman is also recommended.
Baby Face's Blaster	Bonk! Atomic Punch	Bat	This set-up for Scout focuses on safely collecting credits dropped by robots and distracting larger robots. The Baby Face's Blaster can allow Scout to move at blazing speeds, picking up cash with minimal chance of it disappearing, while also letting the Scout attack from a safe distance. Bonk! Atomic Punch not only guarantees safety while picking up the cash, but also provides the Scout with the ability to distract things like Deflector Heavies and Giant Pyros, giving teammates a chance to strike from an effective range. The stock Bat is recommended due to how it provides no health or vulnerability drawbacks, further enhancing the Scout's survivability if collecting money outside of Bonk!'s effect. Recommended upgrades involve increasing the Scout's resistances and/or health regen, due to how Scout's role will be to stay alive while leaping straight into crowds of robots if need be.
Baby Face's Blaster	or Pretty Boy's Pocket Pistol or Mad Milk	Fan O'War	This loadout focus is on building your speed with the Baby Face's Blaster, so that you can run in and tag the higher-priority robots with the Fan O'War. Piercing and damage upgrades for the Baby Face and Pretty Boy's Pocket Pistol are a high-priority, as these will allow you to build your boost faster, and the Pocket Pistols no-fall-damage ability may come in handy when running into the fray off of walkways and such. Alternatively, you can use the Mad Milk to further assist your team by marking large areas of robots with it, however this puts more emphasis on upgrading the Baby Face's performance.
or Soda Popper or Force-A-Nature	Mad Milk	Fan O'War	A loadout for a general support Scout in Mann vs. Machine mode, mainly focusing on increasing the survivability and damage output of the whole team. As primary, for raw damage consider using the Soda Popper as it deals the more damage per second (DPS) among the Scout's primaries in the time it takes a full shoot-reload cycle of the Scattergun. The Force-A-Nature trades DPS for more versatility: it can knockback the bomb-carrier into a pit or keep it from deploying the bomb in the hatch. Its force jump allows you to fastly get money in high ground (some waves in Decoy when robots spawn on the wood platform) and to flank the robots either to take the money dropped behind the horde or to mark for death or kill high priority targets (Giants, Sentry Busters, Über Medics). Over all the secondaries, Mad Milk is the preferred choice. Its ability to heal on damage greatly increases the survivability of your teammates, specially against giants, when teammates cannot benefit from the health-on-kill upgrades of their weapons. Also upgraded Mad Milk slows down the robots, which is very useful to deal with Giant Scouts. Pistols are not a good choice since primary weapons are normally better options to deal damage, being the advantage of shooting targets at long range marginal compared to the benefits of the Milk. The cans are neither recommended since they make you lose some precious seconds when you drink them and their benefits are more efficiently achieved by other means without having to renounce the Milk (Uber canteens for Bonk! Atomic Punch; and Soda Popper, Fan O'War and speed upgrades for Crit-a-Cola) With the Fan O'War you can mark for death high priority targets like giants or Sentry Busters. Since it does not require any investment, it is preferred over the Sandman, allowing for investment in higher priority upgrades. Generally, the health boost provided by the money, the upgrades on resistances and the distraction provided by your teammates may be enough to safely mark a giant in melee range. Recommended upgrades include Movement Speed to dodge projectiles, Slow Milk to slow down Giants and other high priority targets, resistances (depending on the map), Milk recharge rate, Jump height (just 1 point might be enough). If spare on credits, upgrading the Scattergun damage to one shoot Über Medics can be a good choice.

 Soldier

• If you have the Buff Banner equipped and your Rage meter is full, fall back to a Dispenser or ammo pack while reloading. Once you've loaded up, use the Buff Banner to boost yourself and your teammates.
  • Be aware that Sentry Guns will only deal mini-crits if the Engineer is under the radius.
• Be aware that Giant Deflector Heavies can destroy your rockets, and worse, Giant Pyros can airblast them. Consider using a secondary weapon against them, or fire the rockets at the ground when those enemies are facing you.
• Since your rockets may take a while to reach the enemy, remember to fire towards where they're going to go rather than where they are.
• Soldiers are great investors for the Blast Resistance upgrade. It allows the player to rocket jump more without fear of losing any large amount of health.
• The Rocket Launchers have a wide variety of upgrades available which makes them expensive to fully upgrade. Invest in fast reload before upgrading clip size as rockets are loaded one by one.
• The Beggar's Bazooka in particular becomes a devastating weapon because the miss chance is a non-issue -- you're always going to hit something. Max out clip size and reload speed and you might stop an entire wave by yourself. During earlier waves when you don't have the money, stay by ammo kits, preferably large kits, to keep your supply replenished.
  • With clip size, reload speed and firing speed maxed out, you can fire up to 15 crit rockets from a single crit boost canteen if timed correctly.
• The Half-Zatoichi already fully heals on a kill, so adding a heal on kill upgrade means free overheal. It isn't recommended to use the sword regularly due to the honorbound mechanic, but since no robots use one, it's relatively risk-free for a one on one fight against stragglers. Destroying a tank with the sword does not grant a health boost.
• An upgraded Righteous Bison can easily take down swarms of enemies. Investing in faster reload and firing speed can allow a Soldier to be able to take down large groups of robots by himself.
• Consider the Cow Mangler 5000 as your primary weapon for this mode. The Cow Mangler's infinite ammo is sure to be helpful in taking out large groups of robots without needing to worry about your ammo. Note, however, that the charged shot will still use up all of your clip even if you've purchased clip upgrades, you also cannot be crit boosted, with one exception being the Buff Banner.
• Soldiers, along with Pyros and Stickybomb Launcher/Scottish Resistance Demomen, are effective at defending the spawn point if the team is pushed back, since they can quickly fire at robots about to deploy the bomb without needing to aim well.
• Avoid getting too close to groups of robots. You are at a disadvantage in close combat, and can be quite easily picked off if your allies are not nearby.

Example Combinations
Combo			Usage
or Rocket Launcher or Original	Buff Banner	or Equalizer or Escape Plan	For the Soldier who wants to keep his team on the offensive. The stock Rocket Launcher's and the Original's high splash damage is great against crowds and builds up the Banner's meter faster. These are recommended above the other primaries, as they both have the largest splash damage and clip size, two extremely important aspects of taking out crowds with the Soldier. The upgraded banner enables Mini-Crits for the whole team, including Sentry Guns, making it a great damage boost. The Equalizer acts as a last ditch attack in the absence of a Shotgun. Alternatively, the Escape Plan can help you retreat from enemy fire, allowing you to restock on health and ammo and keeping the team on its offensive momentum. After upgrading the Buff Banner, focus upgrading your primary to fill it out quicker. Firing speed, projectile speed, and reloading speed upgrades help you to do the largest possible barrage of rockets. Alternatively, you can focus on rocket damage and projectile speed upgrades first to make sure each rocket is launched at its full potential. ÜberCharge canteens are recommended above others, as your damage input and Buff Banner helps you to make a great push while under its effects. Alternatively, a crit canteen can let you shower crockets onto the enemy, which is enough to kill any regular non-Heavy robot in a single hit.
Black Box	Battalion's Backup	Disciplinary Action	For the Soldier who wants to play a direct, yet supportive role. The Black Box, given how it returns +15 health per hit, means damaging and surviving against groups is much easier. Additionally, since healing rockets allow Soldier to take more damage, filling the Battalion's Backup is much easier, allowing allies to frequently take -50% Sentry damage, -35% general damage, and full crit resistance. Disciplinary Action is additional support to teammates, letting you and a teammate quickly make it back to the front lines and gather money faster. Upgrades should focus on resistances and clip size, which maximizes your potential in taking damage, offsets the smaller launcher clip, and increases the defensive buffs you can provide. Crit canteens give you more a offensive presence, clearing out crowds quickly. Non-Kritzkrieg ÜberCharges aren't recommended, as it defeats the purpose of a healing loadout.
Beggar's Bazooka	Buff Banner	or Equalizer or Escape Plan	Essentially a 'rocket spam' loadout, this will allow you to fire multitudes of rockets with the Begger's Bazooka at the incoming robot hordes, and will very quickly build up the Buff Banner. When you run out of ammo, run to the nearest ammo crate, and on your way back to your firing position let loose with the Buff Banner, and then open up with the Beggars once again. Rinse and repeat ad nauseum. Focus on upgrading reload speed, ammo capacity, clip size, and eventually movement speed, especially if you choose to forego the Escape Plan. Though this loadout can eventually become incredibly powerful, it will likely take several waves worth of credits to build up momentum, and is dependant on your knowledge of where ammo crates are positioned around the map.
Direct Hit	or or Buff Banner or Battalion's Backup or Concheror	or Equalizer or Escape Plan	A loadout for Soldiers facing large mobs of Giants or Tanks. You will be able to hit slow moving Giants reliably with the Direct Hit and deal substantial damage over a short period of time. Upgrade firing speed and reload time to keep up your rates of damage. Your choice of banner depends on your team composition. The Buff Banner can enable the rest of your team to keep up defensive momentum, while the Battalion's Backup or Concheror can keep your team in the fight much longer.
Cow Mangler 5000	or Buff Banner or Concheror	Escape Plan	The Soldier can save the most cash with this loadout, and there are several distinct advantages for the Cow Mangler 5000 as an all purpose general damage dealing Soldier. Firstly, Pyro Robots do not know that the Mangler blasts are actually rockets, and do not know how to reflect them. Thus, they will not. This takes one of the weaknesses the Soldier ordinarily suffers under normal circumstances away. The second advantage, which is the most important feature, is that it is has unlimited ammo, thus a Mangler Soldier can position himself around ammo boxes without fear of taking, for example, a Demoman's source of ammunition refill and act as a helper/guard. This also means the Soldier will save money, as there's no ability to purchase ammo capacity. During early game waves, the secondary fire comes in handy for igniting bots in a radius as well as mini-critting, and scoring additional rage for the Buff Banner. However, once clip size is invested, it should not be relied upon. One optimal route for upgrading the mangler would be to focus on the following in order: Reload speed, firing speed, damage (with points going into health on kill when there's not enough cash), clip size (again, dumping any remaining below $400 into health on kill), and then finally maximizing health on kill. The Buff Banner duration as well as the Soldier's resistances should be focused on after the mangler is sufficiently upgraded. There are only a few down sides: The Soldier cannot crit under any circumstance, and the projectile speed cannot be increased. For canteens, don't bother wasting them on crits. Instead, ubercharge should be purchased. As of recently, the Concheror has gained the ability to increase speed as well as healing per damage dealt. Soldiers who go with the Concheror will be able to aid team members in getting somewhere fast as well as helping them to stay alive. The effect stacks with the run speed upgrades, and a resilient Soldier aiding a Pyro can easily help them circle strafe even the toughest of giants. Considering that any and all damage to enemies by the user with the buff increases the heal amount, more often than not swarms of enemies can be a good means to quickly replenishing lost health in dire circumstances. The speed boost also allows for quick getaway situations or for catching up with runaway super Scouts that get past the main line of defense, giving the team additional seconds to unload their weapons upon it before it's too late and the bomb is deployed. The more damage players can dish out, the more they heal. This is especially when they have projectile penetration on their weapons where applicable. If another player is also a Soldier and using the Buff Banner, a Concheror Soldier can refill their rage much faster when dealing damage under the mini-crit effect, allowing for it to be used much more often and quite more liberally. Engineers will not be able to benefit from the healing ability via their Sentry Guns, only with melee/primary/secondary weapons (minus the Wrangler). However, the speed boost can help an Engineer who doesn't have the Rescue Ranger run away a little more hastily, potentially saving their lives and buildings.

 Pyro

• The Pyro's airblast's versatility drastically increases in this game mode.
  • The airblast is one of the few ways to deal with ÜberCharged giants and can be upgraded to make separating a Medic and patient quicker.
  • The airblast can also push bomb carriers away from the bomb hole.
  • The airblast can lift Giant Scouts and Sentry Busters, allowing the player to continuously blast them in one place for easier elimination.
  • A Pyro with upgraded airblast can single-handedly delay bomb carriers on some maps while the rest of the team focuses on killing a tank.
• Whether dressed in fine suits or plate metal, Spies are flammable all the same. If the Administrator alerts the team to the presence of Spies, start Spy checking.
  • When Spy bots arrive on the map, fall back to the Engineer's Sentry Gun, possibly with a Homewrecker or a Neon Annihilator, to keep his nest intact as long as possible, and remember to Spy check all teammates.
• Upgrading the regular Flare Gun to give it an increased rate of fire allows you to stack up critical hits on burning targets from a safe distance. Consider using this against giants and situations where it can be risky to get in close. Upgrading the Scorch Shot in a similar manner can also allow you to knock back targets and keep them from retrieving the bomb. Keep in mind that tanks do not catch fire, however. The Detonator sacrifices critical hits on burning targets, but you can ignite multiple robots at once.
• Using an Übercharge canteen and your Axtinguisher can allow you to stand up to giants and take them down in short order. Equip the Degreaser to hasten your weapon switch.
• Because of the Pyro's tendency to get close and personal to deal damage, a Return to Base Canteen allows the class to have a quick escape and even chasing power.
• A crit-boosted Pyro can be a reliable and continuous source of damage against Tanks, due to the Flamethrower's high damage rate. Using a Crits canteen or pairing with a Kritzkrieg-wielding Medic, a Pyro can deal very significant damage to a Tank.
• Although the Phlogistinator sacrifices support options, investing in some resistance upgrades and health-per-kill upgrades, combined with well-timed use of the health refill, can allow a Pyro to take on more of a tank role. Along with the crit boost and an Über canteen, you can even take out giants and any Medic bots attached to them single-handedly. Just keep an eye on your ammo reserves, and don't be afraid to invest in some ammo upgrades if you feel you need it.
• The Phlogistinator can increase your Mmmph meter from attacking the tank. This means you have critical hits on the tank the majority of the time. On most maps, a Pyro can even defeat the tank by themselves with damage upgrades.
• Robots always suffer the duration of an afterburn as their Pyro teammates do not airblast them. A hit-and-run strategy combined with burn damage/time upgrades suits the Pyro well.
• The Backburner's guaranteed critical hits from behind mean that you can take on an ambushing support role, quickly cleaning up the remains of a robot mob in coordination with a Sentry or Heavy/Medic combo, or softening up an incoming wave to be dispatched by your allies.
• The Third Degree is invaluable when dealing with Giant Heavies and their retinues of Quick-Fix Medics. Use an Übercharge canteen to close the distance, then attack the Medics with your weapon to remove the giant's source of healing. Once you hit them with your axe, the giant's attention will be on you, so you may want to have more than one Übercharge to assure your safety.
  • If you are able to sneak in, a crit boosted attack from the Third Degree will eliminate all the Medic Bots in one shot. Consider this strategy if you lack a convenient way to dispatch a group of Über Medics healing a giant.
• Make use of the corner to ambush a group or a giant Robot.

Example Combinations
Combo			Usage
Flame Thrower	Reserve Shooter	Third Degree	For missions heavy with Medic Robot support, especially those that send several medics with one Giant Robot, the Third Degree can make quick work of an otherwise tough situation. Light up the giant robot first, then just a few swings with the Third Degree will liquefy all the medics before they have a chance to Uber. Just be sure to have a Medic yourself or an Uber canteen so you can survive going toe-to-toe with a Giant Robot. The normal Flame Thrower is advisable since it has no penalties to Airblast or afterburn damage. The Reserve Shooter with a fire rate upgrade can be used to get a nice burst of damage after airblasting the giant robot. Since you'll be pumping a bunch of money into defense anyway, it becomes preferable over the safer Flare Gun option.
Phlogistinator	Flare Gun	Back Scratcher	This weapon combination for Pyro is capable of crowd control and handling any robot save Giant Pyros, Sentry Busters, and Tanks completely by yourself. The Phlogistinator is the main weapon of the set, due to how easy it is to build 'Mmmph'. The normal Flare Gun is recommended over other secondaries due to how it has higher damage output on giants than any other of the Pyro's secondaries, in addition to building Mmmph at a safe distance. The Back Scratcher gives Pyro a boost to medkit pick-ups, complimenting this Pyro's lone wolf playstyle and letting any Medics worry about less people to heal. ÜberCharge canteens are essential to the set, as a lone Über + Crit Pyro combo is a force to be reckoned with. Use them after the end of Phlogistinator's taunt or if you're about to die during it. Upgrades can vary, but should focus on increasing your overall efficiency during the Mmmph's effect. Maximum reloading speed for the Flare Gun is recommended, as it builds Mmmph quickly and reliably deals heavy damage on giants.
Degreaser	or or Flare Gun or Detonator or Scorch Shot	Axtinguisher	This set is for an Axtinguisher Pyro. Upgrade the Flare Gun's and Degreaser's burn time to deal crits without having to continously re-ignite the robots. The Degreaser's faster weapon switching makes dealing crits faster and easier. The Detonator and the Scorch Shot allow you to ignite multiple enemies at once, so you can quickly take down a group of robots. They also help you to hit the robots easily if you aren't good with Flare Guns. The Axtinguisher is very powerful, doing major damage to any robots that are on fire. This is crucial for when a robot is about to drop the bomb and you need an immediate push to stop it, working very well on giants as well with your fast weapon switch and potential firing rate upgrades. You can further upgrade the your Axtinguisher attack speed as well as health on kill, allowing you to deal heavy damage and survive heavy damage. This setup is also very useful when against Steel Gauntlets as they take in double melee damage so a couple of swings would kill them for sure.

 Demoman

• The robots follow preset paths, so Sticky Bomb carpets are more effective than in normal gameplay. Upgrade for maximum effectiveness.
  • The Scottish Resistance is also a very viable weapon to keep. Its ability to have more traps active in a single time, while being able to detonate off small packs rather than the whole allows the player to cover more ground and lane paths.
• The Critical Hit Boost Canteen can be used to make fatal sticky traps for giants and chip a chunk of health off of tanks.
• If you plan on Demoknighting, consider using the Chargin' Targe, as it has higher resistances than the Splendid Screen, and you'll rarely be using the charge ability unless it's to get out of a jam. Having the maximum amount of heads with an Eyelander, maxing your movement speed upgrades, or a combination of the two, can allow you to circle strafe most giants and avoid their devastating attacks while you hack their legs to pieces.
• Tanks are easy targets for your Grenade Launcher because of how big they are. You can also lay large groups of stickies on their predictable path to take a huge chunk of their health off.
• If you're good at aiming, try using the Loch-n-Load - it does an extra 20% damage, has faster projectiles, and has the same splash damage radius. Beware of the low clip size, though - it might be a good idea to upgrade either clip size, reload speed, or both.
• While not as effective damage-wise, the Loose Cannon's knockback on a direct hit is almost as strong as a fully upgraded airblast. The Loose Cannon can be used as a sidearm for dealing with Über Medic and even for resetting the bomb.
• The Demoman's melee weapons can be upgraded to grant up to four seconds of full crits on a melee kill. Combine an Eyelander, Nessie's Nine Iron, or the Horseless Headless Horsemann's Headtaker with an Übercharge canteen and go on a robot head-hunting spree!
• If possible, between each waves, request a Kritzkrieg Medic to allow you to plant critical Sticky Bomb carpets before the next wave starts, but only if it is a dedicated Medic. Any medics that switch away after a kritz charge will cause the Demoman's stickies under the boost of a Kritzkrieg to disappear, but not rolled criticals. Übercharge rates are significantly boosted during this time. Time the charge and your fire rate, reload rate, and clip size so all of the stickybombs you lay will be critical. If your team doesn't have a Kritz Medic, you may want to buy a Kritz Canteen or two.
• As noted above in the Soldier strategy, the Half-Zatoichi's health on kill bonus stacks, and with the Demoman's shields and semi-unique critical on melee kill bonus, it can be devastating against hordes of bots.
• As with the Soldier, invest in faster reload time so you don't spend so much time reloading your Grenade Launcher or Stickybomb Launcher.
• Unless you are a demoknight, avoid getting too close to groups of robots. You are at a disadvantage in close combat, and can be quite easily picked off if your allies are not nearby.

Example Combinations
Combo			Usage
or or Grenade Launcher or Loch-n-Load or Loose Cannon	or Stickybomb Launcher or Scottish Resistance	or Bottle or Ullapool Caber	A standard, non-melee Demoman loadout. The normal Grenade Launcher is recommended if you plan to focus on large groups of enemies, while Loch-n-Load starts off with more immediate firepower that can be even further upgraded to outclass the Grenade Launcher if aimed well. Your secondary weapon should be decided based on whether you go on offense or defense. The Stickybomb Launcher allows for quicker travel and better crowd control, arming quickly and weakening pushes from the robots. Meanwhile, the Scottish Resistance can be crit boosted at the start of a wave to do 2520 to 4942 in a single instant. At worst, if all the stickies hit their target, the damage enough to take out over half the health of any giant. At best, the damage can singlehandedly instantly blow up any robot except Tanks or Deflector Heavies, the latter of which literally becomes weak enough to die to a single pipe bomb afterwards. Your melee weapon should either be a standard damage weapon (Bottle, Scottish Handshake, Conscientious Objector, Frying Pan, and Saxxy all qualify) or the Ullapool Caber, as everything else hinders your health, ammo, or versatility. Your canteen should be crits, again due to how powerful Demoman is with them. Upgrades can go into reloading and movement speed, removing the Demoman's initial natural flaws and maximizing how fast you can eliminate targets.
Ali Baba's Wee Booties	or Chargin' Targe or Splendid Screen	or or or Eyelander or Scotsman's Skullcutteror Half-Zatoichi or Persian Persuader	A Demoknight set can work well in Mann vs. Machine, provided you have the proper upgrades. Your primary is an important part of the set, as it gives you more bulk and control in your charging. The rest of your set has many options, but some shield and weapon combos work better than others. The Eyelander (or its alternates) and The Chargin' Targe is a classic pair, giving you the peak of bulk and mobility. Chargin' Targe also pairs well with the Half-Zatoichi, as the two together can turn you into quite the juggernaut with your base resistances and ability to heal. Alternatively, the Splendid Screen sacrifices your bulk for more immediate power and mobility. Using it with the Persian Persuader lets you make charges in very short time periods. If used with the Scotsman's Skullcutter, you can kill any regular robot in a single "bash-and-slash" combo, discounting the high-health Steel Gauntlets. Upgrades should always focus on giving you crits and health boosts upon each kill, which will help you clear out entire crowds, as well as increasing your melee weapon's strength via firing rate and damage bonuses. If using the Chargin' Targe, resistance boosts will make you excellent at handling Soldier, Pyro, and Demoman robots. Bullet resistance should be invested in as well, as Scout, Heavy, and Sniper class robots will exploit your average bullet vulnerability. If using the Splendid Screen, charge recharge bonuses can let you potentially deal heavy damage without the on kill crit bonus every 4 seconds. Note that maximum recharge rate used alongside the Persian Persuader lets you perform charges almost non-stop, making you the most mobile class of the entire team. Canteens should focus on ÜberCharge, as crits on kill should be standard while you have no ammo of which to use.
Ali Baba's Wee Booties	Stickybomb Launcher	or Eyelander or Half-Zatoichi	For a Demoman looking to focus on his Stickybomb Launcher, this setup effectively makes the Demoman a "Sticky Tank" of sorts. A more Heavy-like playstyle is to be taken on if this set is to be used effectively. The extra health provided by the Ali Baba's Wee Booties or Bootlegger will stack nicely with the extra health provided by the Eyelander (or its alternates) or the Half-Zatoichi, which in turn will allow you to tank more damage. The Scottish Resistance is discouraged as the extended arm time won't work well with the fact that you don't have another ranged weapon at your disposal. If the robots do manage to get in your face, a few swings with your sword should clear things up.

 Heavy

• Even the Heavy cannot survive the combined fire of larger waves of robots. The Heavy needs resistance and health-on-kill upgrades or a Medic with upgraded heal rate to take on a tank role. Otherwise, wait around corners and use Crit or Über canteens to prevent being overrun.
  • This is also a better investment since the Minigun is more expensive to upgrade than most other weapons. This is offset by the high and sustained damage it inflicts by default.
• Unique to the Heavy is the unlockable ability to knock enemy projectiles out of the sky with his primary weapon. Use this to counter Soldiers and Demomen (Particularly the Giant Rapid-Fire versions of them, and especially Charged Soldiers, as their missiles travel slower and are thus easier to destroy).
• Also unique to the Heavy is the Rage upgrade, which builds when you damage robots. Save the Rage for tougher robots like Heavy specials or Giant Robots (especially Giant Scouts), where they're easier to hit and more valuable to knock back. Don't use the Rage on Tanks since they can't be knocked back.
• Penetrating primary fire makes an excellent upgrade against swarms of robots as your bullets can hit more of them at once, increasing your damage potential and less robots to deal with.
• Watch out for Sniper bots! You're easy pickings for them if you stay in an open area for too long.
• Watch your back when Spies appear. Don't be afraid to give any approaching ally a quick burst or punch, just to be safe.
• Your Sandvich is just as valuable in Mann vs. Machine as in regular gameplay. Use it to keep you in the fray when under fire, or throw it to a fellow teammate that has taken damage.
• The Brass Beast can be useful for situations that require high damage, such as waves with tanks or giant robots. Consider maxing out your Movement Speed to counter the Brass Beast's lower mobility while deployed.
• Natascha can slow down the horde, making it easier for you and your teammates to mop up the robots. In addition, Sentry Busters and Super Scouts will be slowed to a crawl with sustained Natascha fire, allowing for the team to take it out safely, or at the very least buying the Engineer(s) time to get away.
• While the Tomislav can allow you to react quicker when swarmed by bots and keep you mobile, the lower firing rate will only hamper your stopping power, especially when faced with giants and tanks.
  • This can be offset by upgrading Firing Speed twice, and while pricey, it negates the downside. In the end, it is your choice to decide if it is worth the investment.
• If a tank is going to enter the field, consider grabbing a crit canteen from the Upgrade Station. Combine it with your Minigun's continuous firing ability to effectively deal damage to the tank.
• The Huo-Long Heater is excellent at close-up crowd control. Use its ring of fire to mow down robots crowded around the bomb. Its main drawback is its high ammo consumption; upgrade it with increased ammo capacity and use an ammo refill canteen to offset this. If you need to maintain range, stay near a Dispenser.
• Critboosts last for a set time, upgrade your firing speed to make the most of the time you are boosted.
• The Holiday Punch is not recommended for Mann vs. Machine, as robots are immune to being forced to laugh. Use another melee weapon that gives you more utility.

Example Combinations
Combo			Usage
or or Minigun or Brass Beast or Huo-Long Heater	Sandvich	Gloves of Running Urgently	A classic Heavy set, used within Mann vs. Machine. Your primary choice depends on what playstyle fits you when Heavy. The Minigun is well-balanced for being able to keep cover around corners while keeping up firepower against the enemy. The Brass Beast sacrifices mobility for more sheer power against crowds. The Huo-Long Heater chews up ammo quickly, but is very synergistic with any Dispensers an Engineer on your team may have. The Sandvich is recommended above other secondaries, due to how you will never use your shotguns if you mind your ammo, while your other lunchbox items aren't as efficient at keeping you on the field. In addition, having a Sandvich is a huge asset for your teammates, as it can heal your Medics, Engineers, and other teammates at low health, keeping the team's momentum by keeping them alive. The Gloves of Running Urgently maximizes your mobility, and should always be used in this mode as a default if you're taking an offensive role as Heavy. Upgrades should go into your primary's firing speed, which further increases your offensive presence, as well as health regeneration, ammo capacity, and Sandvich recharge rate. ÜberCharge, crit, and ammo refill cantenes are all good options for the Heavy, which one you choose being a matter of the situation at hand.
Natascha	Sandvich	Fists of Steel	A loadout that allows Heavies to stall mobs of fast-moving enemies, such as Scouts and Pyros. Purchase penetration and knockback upgrades early. When combined with Natascha's inherent slowdown effect, you will be able to shut down the forward momentum of Giant Robots, while at the same time damaging support units such as Quick-Fix or Über Medics. The Sandvich can be used to quickly regenerate health if you start to run low. If your position is overrun, the Fists of Steel can be used to quickly withdraw while shielding yourself from enemy fire. Alternately, you can use the protection afforded by the Fists of Steel to safely redeploy from location to location, while minimizing damage from ranged weapons.
or or Minigun or Brass Beast or Tomislav	Shotgun or Family Business or Dalokohs Bar	Fists of Steel	This loadout strategy trades firepower for utility; it's most effective on missions with many ranged attack robots. Your main focus with this set is tanking as much damage as possible so that your teammates can focus on damage output. Upgrade resistances and health regeneration at first so that you can stay on the front lines as long as possible. This strategy requires more mobility, so upgrade move speed at least once when you can. Once you're sturdy enough, upgrade attack speed and health on kill of the Fists of Steel. The damage reduction of the F.o.S., coupled with resistance and health regeneration, allows you to become a near-indestructible tank. You can literally charge right into a horde of robots while taking the brunt of their firepower. Since most robots attack whoever is closest to them, this strategy allows you to keep your team alive and the sentry up. Because of melee weapon's high crit chances, you're great for taking out Medic-bots before they can use their ubercharge; and since you'll be operating at close range, you make a great money collector. You can use the Shotgun or Family Business (with penetration) to deal reliable damage while closing to melee range or while retreating. Alternatively, consider pairing the Tomislav with the Dalokohs Bar to increase your survivability with the F.o.S. while the Tomislav's quick spin-up is useful for dealing quick damage against melee robots.

 Engineer

• Before the wave begins, all your buildings cost no metal, build instantly, and automatically upgrade to level 3 upon placement. Use this to your advantage.
• Ammo and metal are harder to come by in this mode because robots don't drop their weapons when destroyed. This makes Dispensers extremely important, especially for ammo-chewing classes like Heavy and Pyro. Before each round begins, be sure you have a Dispenser set up where everyone can reach it quickly (including you, in case it gets sapped) but not in such obvious sight that the robots target it.
• Sentry Guns will rebuild at an instant when hauling it to another location. This is a good strategy when the bomb carrier has breached your team's defenses or when taking down a tank.
• Sentry Guns are vital for controlling chokepoints and dealing large amounts damage to giants and the tank, but they attract Sentry Busters. Keep an eye out at all times.
  • Generally, the places that contain ammo boxes are ideal to build Sentry Guns.
  • If a Sentry Buster gets too close, grab your Sentry Gun before it explodes, but be careful as it can destroy other buildings near its blast radius and can kill you if you are near it when it explodes.
  • If a Sentry Buster targets your Sentry Gun and you pick it up before the robot activates, the Sentry Buster will chase you instead, arming when it gets near you. This is another tactic you can use to save your Sentry Gun, and it will count for the achievement Real Steal. During a lull, you may also lead the Sentry Buster to your teammates, who can finish it off.
  • If you want to easily survive a detonation from a Sentry Buster, buy an Übercharge Canteen and stand next to your Sentry Gun. Deploy the Canteen's buff when the Sentry Buster crouches, and you and your Sentry will be safe from harm for five seconds. To keep your nest intact, you can also use the above tactic to lead the Sentry Buster away from your other buildings, or pick up a second building to shield it.
  • More Engineers on a team means more Sentry Busters per wave. Sometimes more than one Sentry Buster will appear at once, so be prepared for them.
• Use a Teleporter to cut the travel time between base and the front lines. It may make the difference between safety and Payload delivery. Investing in the two-way teleporter upgrade also makes it much easier for the Engineer to get out of a Sentry Buster's range, since you can teleport back to the entrance before it gets to you.
  • If a single tank is coming and you haven't upgraded to a two-way Teleporter yet, consider building your Teleporter backwards (exit at the base), then haul the Sentry Gun when the tank passes you by.
  • Do not build your Teleporter exit next to your Sentry Gun and Dispenser, so if a Sentry Buster arrives on the field, it'll be one fewer building to worry about getting destroyed. Also, if there is a player being transferred, it will also prevent the death of the player when there is a Sentry Buster exploding.
  • It is also possible to use the Teleporter as a makeshift elevator, to allow teammates to get to higher ground without taking a detour or wading through the robot wave. Place the entrance where allies are likely to take cover, and place the exit at a good vantage point that is not easily accessible otherwise.
  • To create convenience and efficiency for your teammates, place your Teleporter facing the entrance or near chokepoints. Make sure the field of view is large and never place a Teleporter facing a wall.
• It is best to build your Sentry Gun near an edge. Not only does it give you height advantage and protection, but the edge will also serve as an escape route from Sentry Busters, as their explosion will not affect targets on lower ground.
  • Be especially careful where to place your Buildings on waves with Soldiers and Snipers as more difficult hordes love to pick off Buildings from across the map. Use the walls and your environment to prevent them from being seen.
• Consider using your Wrangler if you have one. When you have a 100% upgraded Sentry Gun, the giants will fall very quickly. However, your Sentry Gun is much more accurate than you are, and more efficient as well. Let it take out the regular bots on its own, as Wrangling it against them will increase the likelihood of several getting past you, especially if one of them is the bomb carrier.
• Use your Frontier Justice to rack up revenge crits very quickly from your Sentry Gun. Close-range crit-boosted shots from the Frontier Justice will deal 180 damage. Multiple shots can chip away at a tank or giant robot's health.
  • Using the Destruction PDA on your Sentry Gun will still give you revenge crits for the Frontier Justice. Doing this between waves is smart because you can instantly rebuild your Sentry Gun to level 3 after you destroy it.
• In the hands of a decent shot, a Widowmaker can keep you filled with metal. So long as you produce more damage than you consume metal in the shot, you come out ahead, and even the odd bad shot can be made up with a good hit next shot. And it never needs reloading. Maxing out your maximum metal and investing in a pierce shot upgrade can provide you with a near unlimited amount of ammunition if your aim is sharp.
• The Rescue Ranger can be used as a long range sidearm or to save a Sentry Gun in a pinch, either if you're unable to directly pick up your Sentry Gun on time or to strategically get to a safe area and pick up your Sentry Gun to repair it. The Mark on Death can be a problem, however, especially if you and your Sentry Gun are being swarmed.
• The Pomson 6000 can be used to assist your team with taking out medics and Spy bots. When it hits a Medic, it will decrease the amount of ÜberCharge it has, giving your team more time to take it out. When used against Spies, it will help decrease the amount of time they can recloak, helping your team to kill them faster.
• Buying an additional Sentry Gun will let you place a disposable Mini Sentry Gun so you can spread more damage with both Sentry Guns.
  • Find places with some protections near the robot passages to build the disposable Sentry Guns. Such as a corner of a building, a narrow path on the side.
  • It would be better to face the Mini Sentry Gun towards the robots' attack direction since it will create damages from their back and it takes time for them to shoot back.
  • When the additional Sentry Gun is destroyed, any kills it has gotten also get added as revenge crits for the Frontier Justice.
• Use Building Upgrade canteens to rebuild quickly if your buildings have been destroyed during a wave.
• The Pistol by default has a large ammo reserve so it can have its fire rate upgraded without needing to invest in ammo reserve upgrades early on.
• The Short Circuit can be used to protect your Sentry Gun from rockets and grenades. This can aid your Sentry Gun by protecting it, while it deals out a lot of damage. However, this is usually best done with Giants such as the Giant Demoman and the Giant Soldier.
• Investing on Wrench attack speed and increased total metal upgrades gives the Engineer a higher chance of keeping his Sentry alive when it takes heavy fire or is being sapped. Also, you will build your buildings faster since you wave faster and do not need to find additional metals.
• Faster classes know how to circle-strafe. Your Sentry Gun is not safe if you leave it among a group of robots.
• The Eureka Effect can be used to escape from critical situations or to fast teleport to spawn to buy upgrades and power-ups if there are no threats around.
  • Note that with Eureka Effect equipped you can't move your Sentry so it will be an easy target for a Sentry Buster. In that case you can use a Canteen with Building Upgrade to quick upgrade your newly built Sentry to level 3 or a Canteen with Übercharge to protect it.
• The Southern Hospitality is for the Engineer having trouble with Spy Robots. The bleed damage can spot cloaked Spies, and alert the Spy to your teammates. However, wrenching robots to scrap opportunities do not come up often for the Engineer, and the extra fire vulnerability will be troublesome if a Pyro bot comes close. Choose this weapon with that acknowledged.
• The Jag is a great choice for melee. If there is enough time to rebuild a Sentry Gun or other buildings without a wave of robots incoming, you can save money and time building to a Level 3. The Engineer rarely needs to make a dent in a Robot's head, so the damage penalty can be negligible.
• The Gunslinger is a poor choice due to the decreased damage output of the Sentry Gun. While it can be paired with the Frontier Justice to store critical shots, the Engineer's damage potential compared to other melee options do not compete. This weapon should be avoided as a serious option.

Example Combinations
Combo			Usage
or or Shotgun or Frontier Justice or Pomson 6000	Wrangler	or Wrench or Jag	A standard Engineer loadout, and possibly one of the most important loadouts in any Mann vs. Machine team. Your primary depends on your personal tastes. The Shotgun is reliable and doesn't rely on any factors besides its own ammo, while the Frontier Justice can potentially turn you into a glass cannon should you lose a sentry to a Sentry Buster. With the latter, you can destroy your Sentry after a wave to collect the many revenge crits it has likely built up. Pomson 6000 doesn't require ammo, though its use fluctuates depending on what it's being fired at. The Wrangler is a very powerful tool, as it lets you kill Snipers from afar, handles crowds and giants at a safer distance, and provides additional fire-power against Tanks. Be aware that you cannot move your Sentry while it is being wrangled, meaning if a Sentry Buster exploding your nest is imminent, then switch weapons before it's too late. Your Wrench and its variants are the Engineer's best melee weapon, as it doesn't have the drawback of fire vulnerability, which Pyros will take advantage of, and allows you to move your buildings, a trait essential with Sentry Busters running about. The Jag can be used instead, though it offers less melee potential against Spy-bots. Canteens should focus on instant building upgrades, as they are cheap and vital to maintaining your team's defense should your sentry break. Upgrades can go exclusively into strengthening your Sentry Gun, though faster firing speed for your melee is also extremely helpful, as it lets your Sentry take more DPS during the enemy's pushes. If you have any credits left over near the end of a mission, good upgrade choices include movement speed or your primary weapon.
Rescue Ranger	Wrangler	or Wrench or Jag	The Rescue Ranger forfeits most of the Engineer's own firepower, placing the emphasis on keeping your Sentry in operation. It enables you to repair the Sentry at a distance by shooting at it and, at a cost of 130 metal, you can retrieve it from a distance. Retreat to a safe distance when sentry busters appear and when it is ready to explode, fire and warp it out of danger. This can also be used to quickly redeploy ahead of robots and get the drop on them, especially in combination with sentry jumping. Invest in Metal upgrades early to offset the high cost of ranged sentry retrieval. Be aware that with the Rescue Ranger equipped, you are marked for death while carrying any building, so this set can be risky in situations where there is little cover. Otherwise, the strategy is much the same as the standard loadout.

 Medic

• To make the most use out of your canteen-sharing upgrade, use the Medi Gun with the opposite power, i.e. use the stock Medi Gun with the Kritz Canteen, and use the Kritzkrieg with the Übercharge Canteen.
  • Adding to the above, using the Kritzkrieg with an Übercharge Canteen may be better for your funds and time than a Medi Gun and Kritz Canteen. The Kritzkrieg builds Über faster than the Medi Gun and an Übercharge Canteen costs less to buy than a critical hit Canteen.
• The Vaccinator accomodates a Medic fighting in the front lines very well. Its fast Übercharge rate and number of charges means you can utilize it frequently. Be aware of what robots are coming out and switch resistances accordingly.
• Watch out for Spy and Sniper bots! You're a high priority target, so always be aware of your surroundings, and stay near your teammates for support.
• A good Medic should also have good resistances. Try to upgrade your resistances in order to increase your chance of survival, more survival means more time to heal your allies in front.
• Though a faster healing rate always sounds good, remember that a target at maximum health will give less to the ÜberCharge meter. Try pairing the Heal Rate upgrade with the ÜberCharge Rate upgrade to offset this.
• All classes can purchase health regain upgrades, but the upgrade stacks with the Medic's natural health regain. Use it to shrug off lesser damage and to retreat and recover in more serious situations.
• If there is a non-Demoknight Demoman in your team, use the Kritzkrieg so you can help him lay critical stickybombs on the field before each wave. It's a better choice than Kritz Canteens because the increased charge rate means you can deploy an Über more than once if needed, and it costs no credits.
• Equip the Übersaw if you feel you'll need to deploy an ÜberCharge often. It's easiest to use it on small robots about to deploy the bomb.
  • Sentry Busters do not attack players, they only target a specified Sentry Gun. Use this to your advantage and hit them for some free Übercharge.
• To help increase the effectiveness and longevity of your teammates, consider investing in Overheal amount upgrades. They're relatively cheap, and can boost your teammates health far above normal. Fully upgraded, a Heavy will end up with 750 health.
  • With upgrades to Übercharge rate, you can charge extremely quickly due to constantly trying to fill the large amount of overheal. With upgrades to heal rate, you can keep your team at maximum overheal easily in the middle of firefights, especially if they have a few resistances.
  • Upgrading Overheal Decay rate isn't too vital when paired with overheal amount, since all overheal decays at the same rate regardless of how much overheal health they have, so consider saving it for last, or ignoring it outright.

Example Combinations
Combo			Usage
Crusader's Crossbow	Quick-Fix	Amputator	The Medieval Medic set used with Quick-Fix. The main goal of this set is to completely focus on healing, hopefully to keep your patient on the front lines as long as possible. While the Crusader's Crossbow isn't good for combat, it can help to counter any Sniper robots in the area, as well as heal from afar. The Amputator is probably the Medic's best melee weapon to use, due to how it's a straight upgrade of the Bonesaw with no drawbacks. While Quick-Fix doesn't have overheal, the Medic can provide pseudo-constant ÜberCharge if one gives it healing rate upgrades, making it heal extremely fast, which pairs well with Heavies or Pyros with health-on-kill bonuses. It's recommended that Medic focuses on upgrades to damage resistance and health regeneration. Due to how you will often be a target of the robots, bullet and explosive resistances are recommended to make the most of your natural healing rate. In addition, maximum health regeneration will give the Medic a large 14 health recovered per second, healing yourself from 1 health back to full health in 11 seconds. Defensive upgrades in tandem with healing rate upgrades make both you and your patient hard to take down unless under consistent and heavy fire. The canteen you share should either be crits or ammo refill, depending on whom you're healing.
Overdose	Kritzkrieg	Vita-Saw	This loadout sacrifices personal survival in exchange for maximum ÜberCharge efficiency. The Vita-Saw retains up to 20% ÜberCharge if you die, while the Overdose increases your movement speed the higher your meter is. The Kritzkrieg has many applications in Mann vs Machine, even more so in certain waves. Demomen can have their stickybomb carpets set up with crits if you charge them before the wave starts, which makes waves with Tanks initially a lot easier. Heavies can clear an entire wave of lesser robots very easily if provided with projectile penetration upgrades. Pyros can take down distracted giants very quickly if given crits at the right time and place. ÜberCharge canteens are recommended, as using a Kritzkrieg leaves you vulnerable in all the action. Upgrades should focus on the ÜberCharge's duration and charge rate, giving your patient 14 seconds of lethal damage with approximately 30 second breaks between each ÜberCharge. This means that in later rounds, as long as you stay alive with a patient at all times, you can potentially provide critical hits more than a third of the time you're alive, an incredible feat any Medic buddy could only dream of utilizing.
or Syringe Gun or Overdose	Medi Gun	or Vita-Saw or Übersaw	A set for Medics who lack the Kritzkrieg or Quick-Fix, or want to try the stock Medi Gun in this mode. It's important to remember that the Medi Gun heals and builds up its ÜberCharge slower than its alternatives, so upgrade these two shortcomings as soon as possible. On the flip side, healing a damaged ally increases Über faster than healthy ones - it's a risk. Sharing Crit canteens is not very cost effective with the Medi Gun, so you may want to forego Canteen Sharing entirely and invest the credits into the gun's other upgrades, especially ÜberCharge Duration. The invincibility of the ÜberCharge is most effective for outlasting or distracting dangerous targets, but proves especially helpful to an Axtinguisher Pyro trying to assassinate giant robots. Your primary and melee weapons depend on your playstyle of choice. The Syringe Gun offers more offensive power in a pinch, while the Overdose stacks nicely with movement speed upgrades, but requires you to switch away from the other weapons to use the speed increase. The Vita-Saw can be worth the slight health sacrifice to help prevent respawning after death with 0% ÜberCharge. Alternatively, if you're confident with your melee skills, the Übersaw gives you a way to quickly compensate for the slow Medi Gun charge, but is less helpful otherwise.
Blutsauger	Vaccinator	or or Vita-Saw or Übersaw or Amputator	This set is completely focused on survivability and defensive power. The Vaccinator has a learning curve in which you set the right resistance against the right group of Robots, if used correctly you should at least stay alive enough through the Vaccinator's ability to heal you if your healing target gets damaged by the current resistance you currently have on. If your healing target somehow dies on you, then switch to the Blutsauger in a pinch to escape and preserve your ubercharge. You should also invest some Health On Kills upgrades on the Blutsager to increase your survivability as well as personal resistance against various damages. Melees can vary depending if you want insurance, quickly get some ubercharge, or heal the entire group near you.

 Sniper

• Your role is to eliminate high-profile targets including Medic Robots, Engineer Robots and Giant Robots roughly in that order of priority. Although halting the bomb's progress is critical, your ability to deal tremendous single-shot damage at range means that you should almost always prioritize these targets first.
• Investing in piercing shots or using the Machina can allow you to take out multiple targets. This can come in handy when confronted with a Giant Heavy surrounded by Medic bots. In general, the Machina can almost be considered a straight upgrade over the Sniper Rifle in Mann vs. Machine because of its improved damage, built-in penetration, and the fact that you're not terribly concerned about tracers giving away your position.
• The Hitman's Heatmaker when paired with the reload speed and explosive headshot upgrades allows you to fire exceptionally fast without breaking sights, meaning you can headshot giant robots as much as twice a second. Gaining and maintaining the Heatmaker's Focus is made easy since there's so many targets to kill.
• The Bazaar Bargain, in the hand of a capable Sniper, can deal an extreme amount of damage rapidly to Giants due to Bazaar's heads bonus. Maintaining the Bazaar's head bonus is easy in missions with plenty of Giants around and helpful in harder mission since you can focus on other upgrades like Damage and Penetration before worrying about Charge Rate upgrade.
• The Sydney Sleeper can inflict the Jarate effect to targets from long distances. Focus on giant robots and they will be taken down by your teammates much quicker. You won't have to worry about aiming for headshots so you can make body shots on slow, large robots such as Heavies easily. Increasing your charge and reload rate will allow you to Jarate robots faster.
  • Even though the Sydney Sleeper cannot headshot, it still does the same damage effect with Explosive Headshot upgrades. Use this when faced with groups of robots.
• Use Jarate to help teammates take out large groups of Robots or Giants quickly. Upgraded Jarate slows them down, making them easier targets. This is especially useful against Super Scouts.
• Explosive Headshot is exceptionally useful for taking on multiple robots, especially at choke points. However, be careful when targeting groups of Über Medics. Lethal charged body shots are preferable to explosive headshots in this situation, since the explosion may deal nonlethal damage to nearby Medics and trigger Übercharge deployment.
• If you are not confident in your headshot skills, upgrade primary weapon damage and charge speed before waves with Über Medics such that you can deal at least 150 damage with a fully charged body shot. This will ensure that the Medics will go down without the chance to deploy ÜberCharges. Even if you are good at scoring headshots, it may be difficult to get Medics' heads in view quickly enough due to their tendency to stay behind their giant partners. Being able to one-shot them in the wheel or arm could mean the difference between facing an Übercharged giant or not.
• Giants move at half the speed of regular Robots (except for Giant Scouts), making their enormous heads inviting targets, but they won't be an instantly killed like regular ones. Consider Reload Speed upgrades to get more hits on them more quickly.
• Spy bots will often hunt you down first before going after other targets. If you're in a spot by yourself, keep an eye out for them when their presence is announced, and consider hanging around your teammates until the coast is clear. Alternatively, the Razorback can be equipped during rounds with Spies; it has no upgrades so it costs no credits to use at maximum effectiveness. Spy robots will try to backstab you even if you have a Razorback, so you can equip one to draw Spies near, wait for the telltale shock sound, then turn around and deal with them. Just remember to watch your back afterward as there's no quick way to restock the Razorback once it's used up.
• The Huntsman can be modified to give bleed on hitting a target, but not explosive headshot. This makes it great for giant robots and tighter areas, but not for much else. More than one point may not feel necessary for this upgrade, as the smaller bots die quickly and you can reapply the bleed with repeated shots on giants.
• Consider upgrading the reload speed on your Sniper Rifle. Not only does it decrease the delay between shots marginally, it's also significantly improves the efficiency of Crit Boost canteens. With damage upgrades, even unscoped shots deal heavy single-target damage.
  • Remember to enable Auto-Rescope in Advanced Options for Reload Speed upgrade to take effect. If not, you will still have the normal delay before you can scope in again.
• The Shahansha is not a wise decision as the Sniper is already a low health class. When you take enough damage for the damage increase, you either will be dead in a few seconds or searching for a health source. While melee weapon choice barely matters for the Sniper in mvm, the other melee weapons are better options in this case.
• The Tribalman's Shiv is mainly used to protect yourself from Spy bots. The bleed can show the location of cloaked Spies to your team, and Spy check nearby teammates.
• The Bushwacka is an excellent choice when paired with Jarate. If any regular robots sneak past your team and flank you, dispatching of the heap of metal can be done swiftly. If a Soldier on your team is using the Buff Banner, you can inflict critical shots on Tanks and other robots without Jarate.
  • You can also use the combo to quickly dispatch any Spy bots that are coming after you.

Example Combinations
Combo			Usage
Hitman's Heatmaker	Jarate	Bushwacka	This loadout concentrates on the potential offered by the Explosive Headshot upgrades, a task the Hitman's Heatmaker is well suited for. The weapon's Focus gauge increases for every kill or kill assist you achieve, so by causing an exploding headshot that inflicts enough damage on nearby robots, it's possible to charge the gauge to full in one hit. From there, the Sniper can unleash a steady stream of shots while remaining scoped - as long as kills continue to be made, the Focus gauge will stay charged up. Thus, a patient Sniper with steady aim can inflict a barrage of massive damage against almost everything. Keep in mind that bodyshots are weaker with the Heatmaker, so aim for robots that are easier to headshot than others around them. To set this up, invest almost all your credits into the Heatmaker, prioritizing (in relative order) Explosive Headshots, Reload Speed, Charge Speed, +25% Damage, and Ammo Capacity. Projectile Penetration is helpful, but not necessary. You'll be neglecting upgrades in all other categories, so try to stay off the front lines lines whenever possible. The Jarate-Bushwacka combo is for self-defense to counter Spies or any other robots that get too close, and can also help you build up Focus. To further help your team, spare 200 credits to give Jarate the ability to slow robots. Canteens are mostly irrelevant with this loadout, but you can grab a Crit canteen for waves where you think you may need the quick burst of firepower.
Bazaar Bargain	or Jarate or Cozy Camper	Bushwacka	This loadout is for the Sniper that can get consecutive headshots, focuses on the potential offered by the Bazaar Bargain's Head bonus and Damage upgrades. The weapon's Head counter increases for every headshot you achieve (it doesn't have to be a killing blow), so by just headshot any robots in your sight, it's possible to fill the counter to its' max bonus of 7 relatively fast. By now, a patient Sniper with steady aim can maintains the Head counter and inflict massive damage against almost everything, especially Giants. Remember that every miss/bodyshot while scoped in will reduce the Head counter by 1, so try to aim carefully before fire your shot. Also, keep yourself alive and refrain from switching to different class or changing your loadout as it will reset your Head counter if you do so. Since the Bazaar already gives you increased charge rate as you're getting headshot, you can focus more on other important upgrades like +25% Damage, Explosive Headshots, Reload Speed and Projectile Penetration. When you already have those upgrades at maximum, as well as others like Jarate's Slowdown, you can get Charge Rate upgrade as it will stack with Bazaar's Head bonus multiplicatively. Jarate and Bushwacka is for self-defense, as well as occasional support for your team against robots when they get too close. If the robots are constantly making you flinch, you can equip the Cozy Camper to negate this.
or Sydney Sleeper or Huntsman	Jarate	Bushwacka	With this set, the Sniper is focused on the Jarate status condition. Jarate itself is, naturally, the staple of this set, as you are not only slowing down enemies once you have the upgrade, you are increasing the damage output of both yourself and your teammates. You should always keep as much Jarate on the robots as you can. The Sydney Sleeper can target high risk bots and the upgraded Jarate can slow hordes in addition to making it easier for your team mates to kill them. The Huntsman is ideal for closer-range work, applying bleeding and heavy headshot damage without losing your field of vision, and is more effective against giants if your aim is lacking. The Bushwacka is always a solid choice for when you run out of ammo, making the Sniper a glass cannon against robots coated in Jarate, at the cost of being less effective against Pyro bots.
Machina	SMG	Kukri	To those that want to do plenty of damage with the Rifle from the start, the Machina is a popular choice. Already being able to penetrate players and doing extra damage on a full charge, the Machina is great for both crowd-control and doing tremendous damage with headshots. Due to the inability to no-scope, the SMG and Kukri can help take care of any up-close attackers such as Spies without giving the Sniper additional vulnerabilities. Invest in the Machina first by increasing its focus speed and damage to make full use of the 100% charge benefits. If the crowds are becoming too much of a problem to wait for a full charge, then purchase projectile penetration.
Huntsman	Cleaner's Carbine	Shahanshah	For the Sniper that wants to fight alongside the front lines, this set can help perform a tremendous amount of damage on key targets while using the secondary to take care of larger low-health crowds. The Shahanshah can help the Sniper fight back if he gets ambushed and is low on ammo, taking advantage of the extra damage on low health. It's best to increase the Huntsman's ammo and the clip size of the Cleaner's Carbine first. A single level of causing bleed on targets with the Huntsman can help finish weak targets. You can also give projectile penetration to both the Huntsman and the Cleaner's Carbine to increase your ability to keep up the critical hit boost longer. However, take note that all four levels of increased firing speed are required to completely offset the slow firing speed of the Carbine.

 Spy

• The Spy takes a more versatile role in the game mode, from money gathering to eliminating large targets.
• Robots are always fooled by a disguised Spy, even when you sap them, sap their teammates beside them or bump into them. Unless you are on fire or disguise in front of them, robots will not suspect you.
  • However, if the Spy is blocking a robot from moving for more than 5 seconds, all nearby robots will immediately target the Spy.
• A Spy investing in multiple resistances allows the player to stay in the front lines longer.
• Use your disguise to pick up money that is too dangerous for your teammates to retrieve.
• Whichever disguise you decide to use is largely irrelevant, as the bots will be fooled either way. However, be sure to use disguises that keep you mobile, such as a Pyro or Engineer, as it will help you avoid getting accidentally damaged by a stray shot from a bot.
• Keep a mental note of where the two pushes are fighting at all times. Even with a disguise on, you may end up getting caught in the crossfire.
• Be careful around Pyro robots. You might be accidentally hit by their flames, and once alight, any robot can identify you.
• Consider having a Canteen with Return to Base equipped to escape quickly if spotted.
• The Dead Ringer is useful as after fake death is triggered the robots will be completely fooled. Retreat and disguise while invisible.
• Unique to Mann vs. Machine, the Spy's Sapper can be placed to disable robots. Unlike conventional gameplay, there's a meter that must be left to fill before a Sapper can be used again.
  • Using an ammo refilling canteen resets the Sapper cooldown.
• Upgraded Sappers can disable robots in a radius and slow down giant robots to make them easier to destroy. Use this to slow Sentry Busters to a crawl, counter a Giant Scout's exceptional ability to carry bombs around the battlefield, cut off a Giant's healing sources from several Medic Robots, and stab large groups of robots that are separated from the pack in safety.
• When sapped, non-giant robots can be backstabbed from any angle.
• Sometimes there will be occasions where you won't have time to backstab sapped robots. In this case, simply sap and retreat to safety, and let your teammates take out the sapped robots.
• The Ambassador is great to use in this mode, as bots travel in predictable paths, and giants especially are slow, easy targets with large hitboxes, ripe for headshots. If a situation is too dangerous to get in close, try sniping your target(s) from a distance.
  • You can use the Ambassador to draw attention to yourself from robots, particularly, Giants. Headshotting a Giant Charged Soldier, for example, will draw its fire towards you. If you stay within its sights and dodge all of the rockets, your teammates can safely approach the Giant and deal a large amount of damage.
• An upgraded knife can do major damage to giants. Wait behind where they enter the map and stab them as soon as their invincibility wears off.
  • Be quick to hide or pull out the Dead Ringer as the giant will immediately try to target you if the stab doesn't kill them.
  • Giants may not turn around when backstabbed if they are shooting at your team. Ask a teammate to distract the heavy, and you might land several backstabs on a giant. Combining this with armor penetration or swing speed upgrades allows the Spy to do massive amounts of damage to a giant. Keep in mind that you and said teammate are taking a big risk with this tactic.
• Consider purchasing the +25 Health on Kill Upgrades for your Knife, meaning each of your backstabs will grant you a health boost, giving you a chance to soak up hits before escaping.
• Robots are likely to detect nearby backstabs, albeit with a small delay. Upgrading your knife's attack speed allows you to backstab more robots, and even land one or two more backstabs to a giant robot, before being discovered.
• Tanks cannot be backstabbed or sapped, so focus on the bots and let the rest of the team deal with it, or if things get desperate, drop cover and unload your Revolver into them.
• Heavy Gauntlets take reduced damage from ranged attacks, and they can soak up multiple melee strikes before going down. A Spy can eliminate one with a single backstab.
• You're usually in the best position to take out Medic bots when they come on the field. Sap them to cut off their healing to their patient, then plant your knife into their circuitry before they can recover.
  • Be careful if you're cutting off healing sources of a Giant. Even when disabled by a Sapper, they will still notice a backstab has happened nearby and will immediately target you.
• Keep in mind that sapping a Mecha-Engineer's sentry or teleporter activates your Sapper's cooldown. When forced to choose, the teleporter should take priority.
• The Red-Tape Recorder functions exactly the same as the default Sapper against robots. Against Engineer buildings it can reduce the threat of Sentry Guns by taking them down a level before the Engineer can respond but leave the buildings alive long enough for the Engineer to save them from destruction. Chose according to your playstyle.

Example Combinations
Combo			Usage
or or or Revolver or Big Kill or Ambassador or Enforcer	Big Earner	Dead Ringer	This set is very safe, allowing you to stay alive constantly. The Dead Ringer is the preferred Invisibility Watch, as you will be on the front lines quite often, and the robots will likely focus on you if they realize you are a Spy. The Big Earner is the preferred knife, as it will give you a way to refill your Cloak quicker, as the robots do not drop weapons you could use to refill your Cloak, and robots are always initially fooled by your disguise (even if they bump into you), so you will not have to worry about Spy checking as long as they do not see you disguise. These factors can make the health reduction of the Big Earner negligible, especially with quick use of the Dead Ringer. Your Revolver choice is largely optional, because the damage output of the Revolver is negligible in this mode. In fact, it may be wise to change revolvers between waves depending on the situation should you choose not to upgrade them. The stock Revolver is generally the most useful, having solid firing speed and the ability to get random crits. The Ambassador should be considered if you're confident in your aim, as well as the robots moving in predictable paths. The Enforcer is more useful against Tanks. The only weapon you should not even consider is the Diamondback, as sapping robots does not give you critical hits, although sapping an Robot Engineer's sentry and teleporter will, you will only gain 2 crits at the most.
L'Etranger	Conniver's Kunai	Dead Ringer	With this set, you will not have constant access to your Dead Ringer. However, the health boosts of the Conniver's Kunai allow you to get more stabs in before having to Cloak, eliminate the need for health-on-kill upgrades, and prevent robots from 'powering through' the Dead Ringer's damage resistance. Without the Big Earner, L'Etranger is the preferred Revolver, letting you refill your Cloak in a pinch. Upgrades should include resistence, movement, firing rate for L'Etranger, armor piercing and firing rate for the Conniver's Kunai.

Counter Robot Strategy

General Robot Strategy

• Before each wave, the robots that are set to appear will be listed in the HUD above. Identify what symbols belong to which robot and plan accordingly.
  • The Sentry Buster is never listed to spawn. It will only appear if an Engineer is active and effective.
  • Support robots are not required to kill to finish the wave.
• The bomb path is always indicated during the set-up. Set up along the path for the maximum effectiveness
  • During the wave, if the bomb carrier is forced off the path enough, bomb bots will take the long way around in an attempt to get back on the designated path.
• The bomb carrier gets stronger the longer they hold the bomb. Watch the indicator to know what buffs are active for the bomb.
  • Giant Robots are the exception to this, the indicator will always be full when they pick up the bomb.
• When a Robot is deploying a bomb, it spins its waist 180 degrees and jumps in. At this point, it is impossible to knockback.

Scout Robots

• Scout Robots move the fastest of all standard robots and travel in swarms making them the most effective bomb carriers. Counter Scout rushes by killing them all as quickly as possible before one slips by with the bomb.
• Sentry Guns are an effective anti Scout measure. Be aware that large enough swarms and Sentry AI can result in a few Scouts slipping past.
• Typical Scout Robots either spawn with the stock Bat or the Scattergun and can't switch. Use this to your advantage when facing them directly.
• Most Scout Robots do suffer a slow down once they pick up the bomb.
• Snipers should ignore most Scout Robots and focus on any that pick up the bomb.

Bonk Scout

• Bonk Scouts will drink Bonk! Atomic Punch once they spawn and every sequential opportunity.
• Watch for Bonk Scouts especially if you're a Demoman. If you know a wave of Bonk Scouts are approaching, don't waste your sticky carpet on them.
• Be careful when using explosives against Bonk Scouts. Worst case scenario, the knockback causes the bomb-carrying Bonk Scout to reach the hatch faster.

Minor League Scout

• Equipped with the Sandman, these Scouts can leave careless players stunned and vulnerable not only to the Scout's melee attack but potentially to other stronger robots. A quick Pyro can airblast their balls back at them for a taste of their own medicine.
• Minor Leaguers may be weak, but because they spawn in groups, this can result in a barrage of baseballs being hurled and stunning multiple players.

Major League Scout

• A Giant version of the Minor League Scout, the Major Leaguers use their baseballs more frequently with dangerous accuracy.
• Major League Scouts have very little slowdown once they pick up the bomb. Use Slowdown or Knockback weapons to prevent them from pushing the bomb too far.

Super Scouts

• Do not allow Super Scouts to grab the bomb, as they run faster then a normal Scout and suffer no slowdown once they pick up the bomb.
• Super Scouts are restricted to using their melee (The Holy Mackerel) and possess very little health compared to other Giant Robots. Use Slowdown or Knockback based weapons to make quick work of them.
• When possible, prevent the Super Scout from picking up the bomb by having another robot carry it. Keep the bomb carrier alive and distracted until the Super Scouts are dealt with.

Soldier Robots

• Soldier Robots will spawn anywhere between groups of 2 to 8. This usually results in a barrage of rockets, aimed for the closest or most dangerous target. This makes a Soldier group a dangerous threat to all team members.
• Their projectiles can be destroyed or redirected with the proper abilities. Take advantage of this when playing the proper class.

Buff Soldier

• Some Soldiers spawn with a Buff Banner, Battalion's Backup or Concheror ready for deployment.
• Identify which Soldier is buffing the robots and eliminate it.

Giant Soldier

• A larger version of the Soldier, it doesn't possess any abilities like other giants aside from a large amount of health.

Giant Rapid Fire Soldier

• A Giant Soldier that can unleash a barrage of rockets very quickly. It's best to fight this robot from medium to long range while constantly moving.
• Rapid Fire soldiers will pause momentarily to reload, and cannot fire until they are fully reloaded.

Giant Charged Soldier

• Giant Charged Soldier rockets can kill most classes in a single hit, but move at half the speed of a regular rocket and fire very slowly. Keep as much distance between you and the projectile as possible, or destroy/redirect the projectile if you can.

Giant Burst Fire Soldier

• Giant Burst Fire Soldiers combine rapid-fire rockets with massive crit damage. Unlike the Giant Charged Soldiers, their projectiles speeds are unchanged.
• Giant Burst Fire Soldiers take a while to reload. Use this opportunity to deal as much damage to them before retreating to safety.
• If their rocket launchers are fully loaded, have one "bait" maintain a distance. They won't switch targets until their initial target is dead.

Sergeant Crits

• Sergeant Crits is the "final boss" of the mission Broken Parts.
• Sergeant Crits behaves similarly to Giant Burst Fire Soldiers. However, with a massive 60,000 HP that regenerates, it requires a lot of constant firepower to bring down.
• Sergeant Crits can only target one player at time, and will not open fire until fully reloaded. Abuse these two weaknesses to the fullest.
• Have one class serve as distraction using Übercharge canteens, while the other classes gang up on it and attack using Crit Boost canteens.

Pyro Robots

• Pyro Robots are very dangerous to Spies. If a Pyro robot lights up a Spy, every robot will be immediately aware of who and where the Spy is and will target them.
• Much like regular Pyros, the Robot versions are immune to afterburn effects.

Giant Pyro

• Giant Pyros are extremely lethal at close range with their flamethrower.
• Although their smaller counterparts can airblast, the Giant Robot airblasts at most every opportunity it can. Be wary when fighting him with rockets or grenades.

Giant Flare Pyro

• Flare Pyros launch the Detonator with deadly accuracy. Huddling in large groups can result in multiple players being set ablaze.
• The Detonator will Mini-Crit against you if you are on fire. Take note of this when you are facing one.
• Although not so fast as a Giant Super Scout or Major League, it's speed should not be underestimated.

Demoman Robots

• Demoman robots can launch a volley of grenades at a target. Combined with the fact they spawn in groups make Demomen Robots a dangerous threat to sentry nests and clusters of players.

Demoknights

• Equipped with a Chargin' Targe and an Eyelander, Demoknights can charge and have improved blast and fire resistance, but do not possess the Eyelander's health penalty.
• Upon getting a kill, Demoknights will gain 3 seconds of Crits. Keep your distance to prevent them from gaining this ability to use against your allies.
  • Because they are not Giant Bots, Demoknights may taunt after getting a kill, wasting their Crit buff.

Giant Rapid Fire Demoman

• Rapid Fire Demomen hurl grenades quickly and accurately, making them a very dangerous threat.
• Although it is unlisted, Rapid Fire Demomen can spawn with slightly more health or a faster firing rate.

Giant Demoknight

• Giant Demoknights are very dangerous, with larger melee range, higher health, resistances and the ability to gain Crits upon a kill. Stick to ranged combat when facing them.

Major Bomber

• Major Bomber is the "final boss" of the mission Disintegration.
• Major Bomber is a beefed-up version of the standard Giant Demoman with crits and a massive, regenerating health pool.
• Like Sergeant Crits, it will not fire until fully reloaded, but the sheer range of the grenades and their splash damage makes him more dangerous to approach.
• Have one class serve as distraction using Übercharge canteens, while the other classes deal damage using Crit Boost canteens.
• If at all possible, push Major Bomber into the ditch near spawn, preferably using a Heavy with full Rage upgrades.

Heavy Robot

• Minigun-wielding Heavies are extremely lethal at close range. They can also deal damage quickly due their ability to attack in a group. This makes fighting a Heavy group extremely dangerous the closer one is to them.
• Like Normal Heavies, they possess the most health of all non-giant robot classes, with one variant possessing even more health.

Steel Gauntlet

• Steel Gauntlets posses the most health of all non-giant and special variants. They also possess a resistance to all ranged attacks because of their Fists of Steel. However, they are restricted to melee only.
• Although they possess a weakness to melee weapons, they spawn in groups, allowing them to swarm anyone who gets close. Take care when getting close, attacking only when there are a few around.
• Steel Gauntlets holding the bomb are extremely dangerous. With health regeneration and reduced damage, they are near invincible. It's best to face bomb carrying gauntlets with other players.
• Despite being oversized, they do not count as giant robots. Spies can easily dispatch them with backstabs.

Heavy Weight Champs

• Heavy Weight Champs come in two flavors, Killing Gloves of Boxing Heavies and Gloves of Running Urgently Heavies.
• G.R.U. Heavies always take and give Mini-Crits, but run faster, at near 100% speed.
• K.G.B. Heavies receive crits for 5 seconds among a kill. Because they attack in groups, its best to fight these Heavies from a distance as to not make them a bigger threat.
  • Much like Demoknights, they also have a tendency to taunt after getting a kill, wasting their Crit buff.
• Heavy Weight Champs always spawn in groups, with their only distinctive feature between them being the gloves.

Heavy Mittens

• These rare Heavies are unique among the Heavy Class Robots:
  • Heavy Mittens run as fast as normal classes.
  • Heavy Mittens always Crit, but are equipped with the Holiday Punch. They deal no damage but leave the player vulnerable while they laugh.
  • Heavy Mittens possess the Least amount of health of all Robots. A single Shotgun blast (assuming all pellets hit) can usually dispatch them.
• Anyone is vulnerable to other robots while they are laughing. Keep distance between you and the Heavy Mittens.
  • Because they deal no damage and are always restricted to melee, a Single Heavy Mitten can keep a player pinned laughing until he is killed. Keep this in mind and communicate when you are trapped by one.
• Heavy Mittens have the ability to spawn in other areas much like Spies. Watch your back when Heavy Mittens are listed on the Wave HUD.

Giant Heavy Robot

• An extremely lethal version of the Heavy with an extreme amount of health, this robot requires a lot of coordination to take down.
• The Minigun takes some time to wind up, but once spinning, the Giant Heavy will keep it spinning until it's aggressor is dead or out of range. Keep this in mind when attempting "hit and run" tactics.

Giant Deflector Heavy

• In addition to having the large health and lethality of a Giant Heavy, Deflector Heavies can shoot down projectiles like Flares, Rockets, and Grenades. Try to attack where it is not facing when using projectile based weapons.

Giant Heater Heavy

• Functionaly identical to the regular giant heavy but carries a Huo-Long Heater which creates a ring of fire around itself making approach difficult. Spies should only backstab when weapon isn't spun up.

Captain Punch

• Captain Punch is the "final boss" of the mission Bone Shaker.
• Captain Punch is essentially a Tank with fists. Its massive, regenerating health and ranged damage resistance means it can take a serious amount of punishment.
• In spite of giving less Rage when damaged, a Heavy with full Rage upgrades can still use this ability to repeatedly pin Captain Punch in a corner, rendering it easy to defeat with a constant barrage of projectile attacks.
• Despite its melee vulnerability, using melee is a very risky strategy. One punch can kill any class, even with maxed resistances.

Engineer Bots

• Engineer bots can deploy a teleporter, which serve as spawn points for other incoming robots, as well as a Sentry Gun to defend it.
• The Teleporters they construct act as a spawn point for support bots who give no money when killed but can still carry the bomb. Take the teleporter out at all costs.
• A teleporter that is very close to the players' general area is very dangerous; Robots are invincible the first few seconds after teleporting in.
• Sometimes the Sentry Gun can deny a non-Spy from retrieving money in an open area. Let your team know if a Sentry Gun is preventing you from collecting money.
• Spies are obviously effective against Engineer Bots. However, sapping a building will put the Sapper on cooldown and will not sap other robots or buildings nearby. Spies will have to attack the other building if he wants to take down both the Engineer Bot's Sentry Gun and Teleporter by himself.
• The best way to handle Engineers as a Spy involves backstabbing the Engineer, and immediately pulling out the Dead Ringer right afterwards. The sentry will shoot the Spy and trigger the Cloak. The Spy should then reactivate his disguise and decloak immediately afterwards. Robots will not detect the decloaking. Move over towards the teleporter and then place the Sapper upon it first. They are a much bigger threat than the Sentry Guns because of the invulnerability robots are granted upon spawning.
  • Engineer Robots are smart enough to break Sappers if they see them. Make sure there are no others in the vicinity before leaving the sapped teleporter.
• Robot Teleporters are especially a huge threat towards player Engineers, as brand new Sentry Busters will ALWAYS come out from the Teleporters.

Medic Bots

• Medic Bots are always to considered large threats for their ability to heal and potentially Übercharge.
• When pushed away from their target or their patient dies, Medic bots can attack using a Syringe Gun or Bonesaw to defend themselves.
• Although they can heal any robot, Medic bots tend to "pocket" Giant Robots if they are available.
• A Spy with an upgraded Sapper is effective against clusters of medics escorting their patient. Sap the patient and the Medics will likely be stunned as well, creating an opening to wipe them out.

Quick Fix Medic

• This brand of Medic cannot Übercharge, but has a faster heal rate. In combination that these medics usually spawn in groups of 3 to 8 on the same heal target, its best to take them out before focusing on their patient.

Über Medic

• Über Medics are extremely dangerous because they can build ÜberCharges quickly and deploy them liberally. Target these medics with powerful weapons.
• Unlike in Multiplayer, Übered Targets can still pick up the bomb, gaining their effects and even deploying the bomb while invulnerable. Use Knockback to protect the hatch.
• Über Medics that are healing the same target can, and often times do, deploy multiple ÜberCharges at the same time. Take advantage of this if one has already deployed a Übercharge.
• Über Medics have the tendency to deploy their Übercharge after taking a slight amount of damage. Classes capable of one-hit kills such as the Spy or the Demoman are excellent counters.
• If you lack a convenient way to kill Über Medics, try to use pushback from explosives or airblast to separate the Über Medic from his target.
• Über Medics paired with regular Heavy Robots are arguably the most destructive combination in the entire mode, particularly if spawned in groups, due to having more mobility than the giant versions of either one. Dispose of the Medics as fast as possible or, failing that, use knockback to delay them until the Übercharge ends.

Giant Medic

• Due to their insanely fast heal rate, attacking the Medic's pocket is pointless. Giant Medics need to be taken out first.
• Be sure to take out the Giant Medic before its Übercharge is ready. When deployed, it will effectively negate your efforts.
• Attacking the Giant Medic's pocket will only speed up the Giant Medic's Übercharge rate. Attack only the Giant Medic whenever possible.
• Pyros and Heavies should attempt to push the Giant Medic away from their heal target from a distance. A Sniper or Spy can then take care of the Medic.
• Do not fear a counter attack from a lone Giant Medic, as the Giant Medic will not switch to any other weapon under any circumstance, even if there is no robot to heal.

Sniper Bots

• With the exception of the Bowman, Sniper Robots stick to the role of Support, spawning only when their icon appears on their wave (and announced by the players).
• All non-Bowmen Snipers also possess a Kukri, which they will use against anyone who gets within range.
  • Because of their accuracy with rifles and detections with melee weapons, it becomes paramount to understand weapon heckling.
• Sniper Robots show a blue laser (much like a Wrangler laser) when aiming. This reveals their location and who their target is. Keep moving if targeted and head to them.
• Left unchecked, large clusters of Sniper Robots can lay seige to your team and substantially weaken your ability to defend. Since they are mostly helpless in close combat, one teammate should be sufficient to dispatch them.

Bowmen

• An exception to Sniper Rifle and Sydney Sleeper Robots, Bowmen can spawn as non-support based robots, meaning they can pick up the bomb and spawn in large groups.
• They can accurately headshot with the Huntsman and attack in groups. This makes ranged areas in front of the Bowmen extremely dangerous.
• Bowmen do not produce a laser effect or have a Kukri, relying entirely on their Huntsman.
• Be aware that Bowmen always produce shots in full charge and very fast at it too!

Razorback Snipers

• These Snipers behave like regular Snipers, but are immune to backstabs due to their Razorback. Spies should let other classes take care of them or use their primaries.

Sydney Sleepers

• These Snipers soften up targets with their Jarate. Note where Dispensers and Medics are to remove the Jarate effect quickly.
  • Remember that Mini-Crit effects do not stack, so Crit-a-Cola and the G.R.U can still be used while under the effects of Jarate without worrying about taking additional damage.

Spies

• When Spies appear, the Administrator will announce their presence. Every time a Spy is killed, the Administrator will state how many Spies remain. Watch your back and Engineer buildings when Spies are active.
  • If players are constantly fidgeting (pacing a small section), they are most likely a Spy.
  • Take note during waves which players like using which weapons. If they have a tendency to use anything but their Primary, it can help you detect Spies from the players.
  • When holding a Sapper, the Sapper outline will appear on the Spy, even when disguised.
• Spies always spawn disguised and Cloak in. They also possess the standard loadout.
• Spies never spawn where other robots do, spawning usually in unpopulated areas. Keep note of areas where your teammates aren't to know where Spies may be.
• Spies will backstab any player regardless if they are in range of a Sentry Gun.
• The Spies will usually be very obvious while disguised, following players and never attacking any robots.
• Ocassionally when they are near, chuckles can be heard from them, try to listen and see your surruondings for any Spies.
• Some waves (Like Wave 666 or Wave 4 of Broken Parts) has Spies spawning as the main threat.
  • These Spies appear as a distraction to other robots or tanks in the wave. They also spawn in large groups of at most 8 and can prove infuriating to anyone ill prepared. As such, keep moving and use fire or explosives to take out large groups while also focusing on the other members of the wave.

Sentry Buster

See also: Anti-Sentry Buster strategy

• The Sentry Buster is a very fast bomb on legs. It possesses no attacks aside from a Kamikaze strike which it will use near an Engineer's Sentry or when its health runs out.
• Sentry Busters may not prefer shorter routes, taking alternate routes that keep it active longer. Keep aware of which way the Sentry Busters are moving.
• Be extremely cautious when staying near the Engineer's Dispenser, especially if the Sentry is near it. The blast radius from the Sentry Buster may also kill you when it plants, and you may not be aware when focusing on the fight.
• When the Sentry Buster is about to explode (whether from health or the Sentry Gun), it cannot be moved. Run away, putting any static object between you and the Sentry Buster.

Tank

• The Tank is a giant machine that cannot attack, cannot be slowed down and carries its own bomb. It requires teamwork from all players to destroy.
• Be aware of the environment when the Tank is turning around a corner. Players that get stuck between a static object and the tank will be killed instantly.
• A Tank has a set path that it must travel on.
  • Mannworks has two paths a Tank can travel on, whichever barrier the tank comes through determines which path it takes.
• Tanks do not activate "On Hit" effects. This means that they cannot be coated in Jarate or Mad Milk, Marked for Death, or receive damage from Taunts. They do, however, increase Rage for the Buff Banner or Concheror, Mmmph! for the Phlogistinator and Boost for the Baby Face Blaster.
• Tanks usually spawn with anything that comes from Support. Keep this in mind that this means you can have two or three bombs active at the same time.
• Melee attacks do the most damage-per-second over time. Equip melee weapons with damage boosts and upgrade melee attack speed to max, as well as invest in critical hit canteens.
