'''Mann vs. Machine''' is a co-op game mode released in [[Mann vs. Machine (update)|the update of the same name]]. In Mann vs. Machine, a team of six players attempts to prevent a horde of [[robots]] from carrying a bomb to their base. As well as the AI-controlled enemies and co-op gameplay, another distinguishing feature of the game mode is the ability for players to purchase upgrades for their weapons using in-game currency. All purchased upgrades will last for the duration of the game.

'''Mann vs. Machine''' (commonly abbreviated as '''MvM''') is a co-op game mode released in the [[Mann vs. Machine (update)|Mann vs. Machine Update]]. In this game mode, a team of up to six players attempts to prevent a horde of AI-controlled [[robots]] from escorting a bomb to a drop-point located in a [[Mann Co.]] facility. During the game, players can purchase [[Upgrade Station|upgrades]] for their weapons and various abilities for themselves, such as various [[damage]] resistances, [[Speed|movement speed]] modifications, and improved [[health]] regeneration, using currency obtained by killing the robots, called [[credits]]. All purchased upgrades last for the duration of the game, or until the player resets their abilities at an Upgrade Station. If a player leaves the game for any reason, their upgrades are retained, providing they reconnect, as well as any credits the player has spent and/or has remaining.

Players have the option of playing [[Boot Camp (Mann vs. Machine)|Boot Camp]] or [[Mann Up]]. Although they do not differ in difficulty, Mann Up allows for players to receive [[Items|rewards]] at the successful completion of a Mann Up mission and even greater rewards at the successful completion of a [[Tour of Duty]], most notably [[Botkiller weapons]], [[Australium weapons]], and the exceedingly rare [[Golden Frying Pan]]. In order to play a Mann Up mission, the player must have a [[Tour of Duty Ticket]] in their [[backpack]]. Upon the completion of a Mann Up mission, the Tour of Duty Ticket used is consumed and no longer available in the player's inventory. Players can also increase the amount of [[Item drop system|item drops]] for their entire team in Mann Up with a [[Squad Surplus Voucher]].
 +
 
 +
Mann vs. Machine mode currently has five separate difficulty levels: Normal, Intermediate, Advanced, Expert, and [[Caliginous Caper (mission)|Nightmare]].

[[File:MvM bomb.png|thumb|250px|right|The bomb]]
The team is attacked by a horde of AI-controlled robots, and must try to prevent the robots from successfully delivering a bomb to the players' base (as in [[Payload]]). Each robot destroyed provides the players with money (when one player collects a money pile, everyone benefits and earns some money). Between waves of robots, the players have the chance to upgrade their weapons at an Upgrade Store using this money. They may also upgrade abilities for their current class. The upgraded abilities are kept, even while switching to a different class, but the purchased abilities are only available for the class that they were purchased for.
+
AI-controlled robots attack the defending team in waves. The player's objective is to try to prevent the robots from successfully delivering a bomb to the player's base (somewhat similar to [[Payload]], though the bomb itself is carried in a similar fashion to [[Capture the Flag|Intelligence]]). Most robots provide the players with [[credits]] when destroyed, in the form of dropped "cash" piles of various sizes. When a player collects one of these "cash" piles, the resulting credits are awarded to all players. At any time during the match, players may upgrade their weapons at an [[Upgrade Station]], usually inside their base, using these credits. Players may also upgrade abilities for their current class. All upgrades for weapons and abilities are kept, even while switching to a different class (though classes can not be switched during a wave), but the purchased abilities and weapon upgrades are only available for the class that they were purchased for. Optionally, players may "refund" their credits between waves in order to change to different weapons, classes, or to optimize for a specific wave.
 +
 
 +
If the players lose against the robots, the game restarts from the beginning of the wave that the players lost, until the players complete the wave successfully. This can occur as many times as are necessary. Players may also vote to restart the map entirely.  
  
For a fee, the Upgrade Store can also fill a player's [[Power Up Canteen|Canteen]] with a buff&mdash;such as personal [[ÜberCharge]], a five-second critical hit boost, or ammunition refill&mdash;or an ability such as rapid building upgrades for [[Engineer]]s or the ability to teleport back to the spawn point. All of these Canteens each provide up to three uses.

Most of the robot horde is made up of plain robotic versions of the nine player classes, typically using basic or mediocre weaponry. However, there are also a number of [[Robots#Variants|special robots]] with unique abilities and/or weaponry.
  
Most of the robot horde is made up of plain robotic versions of eight of the nine playable classes (there are no robot [[Engineer]]s), with their respective basic weapons equipped. However, there are also a number of [[Mann vs. Machine (update)#Special Robots|special robots]] with unique abilities.

While a robot carries a bomb, it loses half of its speed. However, the bomb-carrying robot gradually receives various buff effects, causing them to grow more dangerous and harder to kill. A HUD graphic displays the amount of time until the next buff. Buffs are activated by the bomb carrier via taunting, setting off [[Media:Mvm warning.wav|an accompanying audio cue]]. These buffs are divided into three stages, which stack together:

Players may use their accumulated credits at an Upgrade Station for the purchase of personal abilities for themselves, or for upgrades to their equipped weapons.
 +
 +
Players may also opt to fill their [[Power Up Canteen]] (if they have one equipped) with charges of a special buff effect — a five-second personal [[ÜberCharge]], a five-second [[Critical hits|Critical hit]] boost, [[Ammo|ammunition]] refills, or the ability to teleport back to the spawn point. [[Engineer]] players may purchase a Canteen effect charge which allows for an instant, simultaneous upgrade for all of their [[buildings]].
 +
 +
Players may purchase up to three uses of these effects at a time. Note that effects cannot be mixed-and-matched; players may only purchase multiple charges of the same effect. Purchasing a separate effect charge switches the canteen over to that effect, discarding the existing effect in the process.

{{see also|Mann vs. Machine strategy}}
+
For the sake of identification, all human players are placed on RED team (identified as team MANNCO), while all robots use BLU colors in their visual effects and in the kill feed. Games are played in waves, each containing a pre-set number of enemies. Various support classes can also spawn in periodically until the wave is over.<!--Maybe these last 2 sentences should be removed since 3rd paragraph repeats this info but with more detail?-->
 +
 
 +
When at least three players enter a Mann vs. Machine server, the option to ready up is enabled. Once one player declares they are ready, a 150-second countdown clock begins. As more players ready up, the countdown clock reduces to a minimum of 60 seconds until all players are ready. When all players are ready, the countdown reduces to 10 seconds. When the countdown ends, the wave begins. Players joining the server during the countdown do not increase the time.
 +
 
 +
Waves are constructed of a pre-set number of enemies that must be destroyed to win. A majority of waves also have "support" enemies that perform a variety of support functions. The most common supports are Snipers and Spies that spawn at set intervals throughout certain waves and generally do not drop money or go after the bomb. Other supports usually spawn continuously throughout the wave or during the last section of a wave. They usually drop a limited amount of money (so that money cannot be farmed) and also attempt to carry the bomb. While [[Sentry Buster]]s are never listed as support enemies, they may appear on any wave if the team has an Engineer that reaches certain kill or damage thresholds with their [[Sentry Gun]]. If all non-support enemies are destroyed, the wave ends and all support enemies immediately die. If the support robots still had money left to drop, it is automatically collected.
 +
 
 +
Before each wave begins, the defenders are shown relevant information in the top HUD, such as the enemies the next wave contains, the current wave, and the number of waves for that mission. Pre-set enemies have a number under each icon to indicate how many are present in the wave, while support classes are listed to the right-hand side. A flashing blue icon means that the enemy or enemies always fire [[Critical hits]]. Note that typing <code>cl_mvm_wave_status_visible_during_wave 1</code> into the [[console]] makes some of this information visible at all times, which can be very useful for players trying to learn a new wave.
 +
 
 +
During pre-wave intervals, Engineers are able to instantly place level 3 buildings or upgrade existing buildings by 1 level per melee hit. Medics also have a notably faster [[ÜberCharge]] fill rate, however it is still slower than the normal pre-game fill rate in the other modes.
 +
 
 +
Once the wave begins, the top HUD changes to show a strength gauge depicting the quantity of pre-set enemies left. Robots begin spawning into the battlefield in groups. Until the robots are in areas that are accessible by players, attacking one does nothing but cause it to glow as if it was ÜberCharged. During the wave, information about certain enemies may appear in the top HUD, much of which is also announced by the [[Administrator]]. Note that [[Sniper Robot|Snipers]] are not announced by the Administrator, and are instead called out by the players via automatic [[Responses|voice responses]]. These responses may also announce the presence of [[Tank Robot|Tanks]], Giant Robots, and [[Sentry Buster]]s on the field as well.
 +
 
 +
* '''[[Sentry Buster]]''' - Sentry Busters are large, bipedal pressure mines that run, stop, and self-destruct near [[Sentry Gun]]s. If an Engineer is moving their Sentry Gun, the Sentry Buster chases them. These enemies only appear in response to effective Sentry Guns built by an Engineer on the defending team and spawn more often if there are multiple Sentry Guns. A common strategy is for the Engineer to pick up their Sentry and run away from other players on the map and touch the Sentry Buster. This causes the Sentry Buster to stop and then explode, before which the Engineer can escape with his Sentry Gun. Another common strategy is for the Engineer to sacrifice their Sentry Gun, by allowing the Sentry Buster to destroy it in a safe location. This stops the Sentry Busters targeted at that Engineer from spawning for a period of time.
 +
 
 +
* '''[[Tank Robot|Tank]]''' - Heavily armored tanks enter the field from specific entry points. These do not attack players directly, but move implacably towards the bomb hatch until they are either destroyed, or reach their destination. Knockback, slowing effects, and debuffs such as [[Marked For Death]] do not affect them at all. Tanks also resist 75% of Minigun damage, severely reducing a Heavy's damage output against them. Unfortunate players can be [[Environmental death#Crushing|crushed]] if they get caught between a Tank and a solid object. Tanks do not carry or retrieve the main bomb, as each one contains its own.
  
For the sake of identification, all human players will be dressed in RED and will be identified as team DEFENDERS while all robots will have BLU colors in their visual effects and in the kill feed.
+
* '''[[Sniper Robot|Sniper]]''' - Sniper Robots spawn like regular robots, but mostly try to snipe players from a distance instead of running with the horde. All Sniper Robots are unable to [[headshot]].
  
Before each round begins, Defenders will be given a graphic indication of the impending onslaught. Primary targets will have numbers underneath them and will be classified by class or (in the case of special robots) their specialty. Red groups indicate tanks as well as giant robots. Support targets will be noted as such and will tend to be focused on attacking the players rather than carrying the bomb (though some like Scout supports will try to carry the bomb at times). Snipers and Spies are always assigned support roles.
+
* '''[[Spy Robot|Spy]]''' - Unlike other robots, Spy Robots have custom spawn points littered throughout the map and usually spawn at the closest one to a player as long as a player is not directly looking at it. They can [[disguise]] as friendly players, [[backstab]] players, and can [[Sapper|sap]] Engineer [[buildings]] (they ignore [[Teleporters]] like all other robots). The Announcer calls out to indicate when Spy Robots appear and when they have been destroyed.
  
When at least three players enter a Mann vs Machine server, the option to begin play is enabled. During the setup phase before the robots arrive, Engineers are able to instantly place buildings, fully upgraded to level 3, at no metal cost, and Medics can instantly fill their [[Übercharge]] meters and rapidly max out ally [[overheal]]s. Once one player declares he is ready, a 150-second countdown clock will begin. As more players acknowledge they are ready, the clock time will be reduced in 30-second intervals (to 120, 90, 60, and 30 seconds, respectively, depending on the number of players present). If all players acknowledge that they are ready, the round is committed and the clock is reduced to ten seconds. Regardless of how it is done, once the countdown ends, the robots will begin their approach to the field.
+
* '''[[Engineer Robot|Engineer]]''' - Engineer Robots can enter in two ways - one more common variation of the robot teleports into the map in preset locations near the bomb, while two rarer versions with a little over half of the other variation's health enter normally. Upon reaching a predetermined nest area, the Robot Engineer commences building a [[Teleporters|Teleporter]], which acts as a forward spawn point for the robots (not including giant robots and robots carrying the bomb), and a [[Sentry Gun]] to defend it. The Announcer calls out when an Engineer Robot has teleported in or if one has appeared, and upon defeating an Engineer Robot the Announcer calls out that it has been destroyed, but if its teleporter is still open she says so as well.
  
Robots cannot attack or be damaged until they jump down into the players' field. A strength gauge will appear to note the remaining forces of the wave. Only primary targets count towards this progress. As they are destroyed, the gauge will empty. Once it is completely empty, the wave is defeated. During the wave, support icons may appear to indicate a specific threat.
+
After each successful wave, the defenders are evaluated based on how well credits were collected, with a credit rating ranging from '''F''' to '''A+'''. If all the credits are collected (the A+ grade), the defenders earn a $100 bonus. If 5% or less of the wave's total credits are missed, the defenders instead receive a $50 bonus. If over 5% of credits are not collected, the defenders receive no bonus at all.
  
* '''Sniper''' - [[Sniper]]s are entering the field. They enter like regular robots but will be focused on attacking players from afar. Snipers will always display visible lasers from their rifles when scoped, making them easier to spot. Beware of their Special counterparts the Bowmen. They don't produce visible lasers.
+
Once a mission is completed, the defenders are given a final evaluation, and the server loads the next Mann vs. Machine map after an interval of 20 seconds. In Mann Up mode, defenders receive item drops and exit to the matchmaking lobby after an interval of 90 seconds, and this time decreases depending on how many defenders are still in the server or are finished viewing item drops.
* '''Spy''' - [[Spy]] robots are on the field. Unlike the other robots, these used their [[Invisibility Watch|cloaks]] to infiltrate the field and will enter from the player's side of the field (which means they'll be coming from behind you most of the time), [[Disguise Kit|already disguised]] as a human. They will act as your average Spy would: [[Sapper|sapping]] Engineer buildings and attempting [[backstab]]s.
 
* '''Sentry Buster''' - Sentry Busters will fixate on a [[Sentry Gun]] on the field and try to get close to it. If it reaches the Sentry or runs out of health, it will stop and then explode powerfully after two seconds, destroying all buildings and players within the explosion's radius.
 
* '''Tank''' - Heavily-armored tanks will enter the field from specific entry points. They won't attack but will move implacably towards the bomb hatch until they are destroyed or reach their destination.  Tanks do not need to carry or retrieve the main bomb as each one contains its own bomb.
 
  
After each successful wave, the defenders will be evaluated based on how aggressively money was collected (with a grade ranging from a low of '''F''' to a high of '''A+'''). If all the piles of money are collected (the A+ grade), the team will earn a $100 bonus. Once a mission is completed, the defenders will be given a final evaluation and the server will load the next Mann vs. Machine map.

*Models of robots of the RED team can be found in game files.

<!-- All of these can be found in the game files -->
*An Engineer model exists in the game files, yet it is not used in any of the Missions.  
+
* RED versions of all of the robots (besides the Tank and Sentry Buster) can be found in the game files.
 +
* Tan/skin colors were originally going to be used for the robots ([[Sniper Robot]]'s tan head textures can be found in game files).
 +
* The robot mothership originally made a humming sound the first two days MvM was released, but was removed later.
 +
* Expired cash would have originally made a sound, but was ultimately scrapped.
 +
* All giants originally had their own unique footstep sounds.
 +
* There's an unused siren sound which is similar to an air raid siren.
 +
* There is an "endless" mode left over in the game that has the players fight randomly generated waves of Robots.
 +
** This mode can be enabled through the developer console with the command <code>script Convars.SetValue("tf_mvm_endless_force_on", 1)</code>, through [[VScript]], or with [[SourceMod]] plugins by setting the <code>tf_mvm_endless_force_on</code> server variable to 1.
 +
** The Robots are be able to "buy" upgrades, being allotted a certain amount of credits based on the current wave, and are limited to pre-defined sets of upgrades.<ref>game/server/tf/player_vs_environment/tf_population_manager.cpp:L1901</ref>

** Losing a wave resets the players to wave 1, regardless of how far they got.
 +
** There is very little setup time between waves, with waves going almost directly into each other.
 +
 
 +
== Bugs ==
 +
* Sometimes a menu such as team, class, or upgrade choice freezes on screen, forcing the player to refresh the HUD (this can be accomplished by typing <code>hud_reloadscheme</code> in the [[console]] or pressing {{key|TAB}}).
 +
* When killed by a dead robot, such as by afterburn, or when removing a destroyed Spy Bot's Sapper, the kill feed may show that the robot has moved to spectator mode. This is due to an internal routine that reassigns robot players for the next attack.
 +
* If the TotalCount in a WaveSpawn cannot be evenly divided by the amount of robots in the WaveSpawn's Squad, the game spawns a full Squad that exceeds the TotalCount. This causes some Wave Summaries to display an incorrect amount of robots, such as wave 4 of [[Mannslaughter (mission)|Mannslaughter]] which displays 13 Medics, however the wave actually spawns 15.
 +
* Sometimes, after a wave is complete, the Administrator continues to issue warnings about the bomb's progress. This does not affect gameplay in any way.
 +
* Robots that are destroyed while speaking and players who are killed while using Mann vs. Machine-related responses continue speaking after their destruction/death. Tank Robots that are destroyed as they stop to deploy the bomb continue to play the "buzz and ding" sound sequence.
 +
* It is possible for the Administrator to announce that a mission has failed when it has not. This can happen when destroying the bomb carrier as it is about to drop into the bomb hole. The bomb hatch is destroyed, but the game considers the bomb undeployed. In this case, the following bomb carriers never make it to the hatch as it continues to kill anything that steps on it.
 +
* Sometimes, when a Mann Up mission is finished, the loot screen shows up empty. This can be fixed by entering <code>hud_reloadscheme</code> in the console.
 +
** If this occurs during server maintenance, the {{code|reloadscheme}} command does not work because the server was unable to return the loot. If pressing {{key|Tab}} still shows tour numbers, players likely receive their loot later; however, if the tour numbers are all gone, players most likely do not receive any loot, but also do not lose their tickets.
 +
* There are a small number of Sentry Gun placements that are immune to Sentry Busters. If the target Sentry is in one of these areas, the Sentry Buster spawns and, without jumping down or exiting spawn, they detonate.
 +
* Certain sounds become stuck in a loop if a wave is failed while they are playing. A notable example of this is the Sentry Buster ticking sound. This can be fixed by typing <code>snd_restart</code> into the console.
 +
* Rarely, before the round, the bomb appears in the spawn points for the robots for all maps with no robot carrying it. An extremely rare case of this is the bomb being teleported to the hatch at the start of the round.
 +
* Rarely, most of the robots' voice lines may not be robotized at all. For example, the death cry of an Engineer Bot or the laugh of a Sentry Buster.
 +
** This can also happen if a robot speaks while far away from the player, most commonly occuring with Spy bots (with the exception of the map-wide laughter).
 +
* Sometimes the Robot Spy's map-wide laugh voice line is cut short (this is because the robot Spy's voice files have a second delay on them).
 +
* Sometimes, on Mann Up servers, a glitch occurs in which players are unable to join the server. The only way to fix this is for every player to leave the server.
 +
* Rarely, if an Engineer Bot's Teleporter is not destroyed by the time the wave ends, the Teleporter does not self-destruct and continue spawning robots when the next wave begins.
 +
* Occasionally, if a Giant Robot is destroyed with the Medic's Projectile Shield, it dies as a [[ragdoll]] rather than exploding.
 +
** This can also happen with any weapons that would cause ragdolls to normally be vaporized, such as the [[Cow Mangler 5000]].
 +
* If a player is inspected during setup or mid-game, upgrades may be lost. If occurring during setup, money spent on the lost upgrades is refunded. If occurring mid-game, however, there is no refund on lost upgrades.
 +
** This happens most often with building upgrade canteens.
 +
* Rarely, robots may stop spawning, causing the wave to be unbeatable. This can only be fixed by restarting the map.
 +
** Before restarting, check around the map for a lone bot that may have wandered to the hatch. Sometimes bots head to the hatch without the bomb and delay the next sub-wave from spawning as all the other bots need to die before it can continue.
 +
* Sometimes, when playing two Mann Up missions in one play session, the second mission completion loot screen may show the loot screen from the previous mission and the notification for "Found Items" does not show up. Items are still obtained after updating the backpack.
 +
** Other times, it fixes itself after a few seconds.
 +
* Rarely, a human ragdoll appears rather than a robotic one.
 +
** This usually happens when Spy bots are killed far away from the player - for example, a Spy dying right before the player takes a teleporter from spawn would appear to have left a blue human ragdoll.
 +
* Very rarely, a RED Demoman's projectiles may appear to be blue instead of red when fired. Damage to enemy robots is unaffected.
 +
* Entering a wave that is in progress during the setup phase causes the Announcer to not say anything and no music to play. The rest of the waves play normally, however.
 +
* There is a random chance for an [[Ullapool Caber]] to spawn in mid-air when a Sentry Buster spawns.
 +
** The Caber spawns in random places around the map, and cannot be interacted with.
 +
* Rarely, when connecting to a server, the player is connected to a different match while still on the load screen.
 +
** This sometimes results in the game placing the player in an empty server with no robot waves.
 +
* Sometimes, the model for the Demoman robots appear as Sentry Busters. They do not possess the ability to explode, as this bug only affects the model and not its mechanics.
 +
* When a player readies up, their confirmation voice clip is played by every player's class, causing them to animate their faces as if they were saying the line as well.
 +
* Robot Spy disguises sometimes appear to have the wrong team colors on certain cosmetics.
 +
* Sometimes, the HUD at the top of the screen does not count the death of a Robot. The icon stays at the top, but once the last Robot is killed the wave ends.

== Notes ==
<!---Do not add First person human hand when spectator on Robot bug. It's not bug.-->
+
* Mann vs. Machine uses a separate set of "Best Moments" and thus keeps track of a separate performance report. These appear after the usual set of "Best Moments" as a client connects to a server.
* Sometimes a menu such as team, class, or upgrade choice will freeze on screen, forcing you to refresh the HUD. (This can be accomplished by typing ''hud_reloadscheme'' in the [[console]])
+
* Normal [[achievements]] cannot be obtained while playing this game mode. The only achievements obtainable in Mann vs. Machine are the [[Mann vs. Machievements]].
* The hole in which the bomb is placed kills everything, including bots carrying bombs.
+
* Optionally, players can utilize .pop files to create custom waves of robots, either for practice or to create entire new missions.
* When killed by a dead bot, such as from afterburn, the killfeed shows that the bot has moved to spectator mode. This is due to the internal routine that reassigns bot players for the next attack.
+
* Between waves, if a Demoman shoots stickies Crit boosted by the [[Kritzkrieg]] and the Medic switches classes, the stickies will break without exploding.
* In the upgrade station, upgrading a canteen can sometimes fill differently than what you selected. (example: You selected to buy 1 uber, and got 2 fills with the price of 2.)
+
** This does not occur if the Medic shares a [[Power Up Canteen|Become Crit-Boosted canteen]] when upgraded with Canteen Specialist.
* Sometimes when a robot delivers the bomb, the game will continue. The hole will remain for the entire session and it will be impossible to fail, unless a second bomb is delivered (for example, if a tank is in the mission)

This article is about the game mode. For other uses, see Mann vs. Machine (disambiguation).
The bomb hatch on the map Coal Town.
Gray Mann has built an unstoppable automaton army with a single purpose: to destroy all things Mann Co. Luckily for you, the majority of this robot legion is equipped with basic weaponry that could never level an entire building. Unluckily, they also have access to giant bombs, which they’d drag through hell if it meant dropping one in a Mann Co. bombhole. And it’s up to you to stop them.
Mann vs. Machine publicity blurb

Mann vs. Machine (commonly abbreviated as MvM) is a co-op game mode released in the Mann vs. Machine Update. In this game mode, a team of up to six players attempts to prevent a horde of AI-controlled robots from escorting a bomb to a drop-point located in a Mann Co. facility. During the game, players can purchase upgrades for their weapons and various abilities for themselves, such as various damage resistances, movement speed modifications, and improved health regeneration, using currency obtained by killing the robots, called credits. All purchased upgrades last for the duration of the game, or until the player resets their abilities at an Upgrade Station. If a player leaves the game for any reason, their upgrades are retained, providing they reconnect, as well as any credits the player has spent and/or has remaining.

Players have the option of playing Boot Camp or Mann Up. Although they do not differ in difficulty, Mann Up allows for players to receive rewards at the successful completion of a Mann Up mission and even greater rewards at the successful completion of a Tour of Duty, most notably Botkiller weapons, Australium weapons, and the exceedingly rare Golden Frying Pan. In order to play a Mann Up mission, the player must have a Tour of Duty Ticket in their backpack. Upon the completion of a Mann Up mission, the Tour of Duty Ticket used is consumed and no longer available in the player's inventory. Players can also increase the amount of item drops for their entire team in Mann Up with a Squad Surplus Voucher.

Mann vs. Machine mode currently has five separate difficulty levels: Normal, Intermediate, Advanced, Expert, and Nightmare.

Mechanics

The bomb

AI-controlled robots attack the defending team in waves. The player's objective is to try to prevent the robots from successfully delivering a bomb to the player's base (somewhat similar to Payload, though the bomb itself is carried in a similar fashion to Intelligence). Most robots provide the players with credits when destroyed, in the form of dropped "cash" piles of various sizes. When a player collects one of these "cash" piles, the resulting credits are awarded to all players. At any time during the match, players may upgrade their weapons at an Upgrade Station, usually inside their base, using these credits. Players may also upgrade abilities for their current class. All upgrades for weapons and abilities are kept, even while switching to a different class (though classes can not be switched during a wave), but the purchased abilities and weapon upgrades are only available for the class that they were purchased for. Optionally, players may "refund" their credits between waves in order to change to different weapons, classes, or to optimize for a specific wave.

If the players lose against the robots, the game restarts from the beginning of the wave that the players lost, until the players complete the wave successfully. This can occur as many times as are necessary. Players may also vote to restart the map entirely.

Robots

Main article: Robots

Most of the robot horde is made up of plain robotic versions of the nine player classes, typically using basic or mediocre weaponry. However, there are also a number of special robots with unique abilities and/or weaponry.

While a robot carries a bomb, it loses half of its speed. However, the bomb-carrying robot gradually receives various buff effects, causing them to grow more dangerous and harder to kill. A HUD graphic displays the amount of time until the next buff. Buffs are activated by the bomb carrier via taunting, setting off an accompanying audio cue. These buffs are divided into three stages, which stack together:

Stages Upgrades Time Interval
(Seconds)
Bomb carrier defense.png
First stage
Defense buff similar to the Battalion's Backup but without the Critical hit immunity, shared with all nearby robots 5
Bomb carrier health.png
Second stage
45 health regenerated per second 15
Bomb carrier crits.png
Final stage
Unlimited Critical hits 15

Giant robots cannot receive these buffs, nor do they lose speed while carrying a bomb.

Abilities and Upgrades

Main article: Upgrade Station
See also: Credits
A sample weapon upgrade menu for the Grenade Launcher.

Players may use their accumulated credits at an Upgrade Station for the purchase of personal abilities for themselves, or for upgrades to their equipped weapons.

Players may also opt to fill their Power Up Canteen (if they have one equipped) with charges of a special buff effect — a five-second personal ÜberCharge, a five-second Critical hit boost, ammunition refills, or the ability to teleport back to the spawn point. Engineer players may purchase a Canteen effect charge which allows for an instant, simultaneous upgrade for all of their buildings.

Players may purchase up to three uses of these effects at a time. Note that effects cannot be mixed-and-matched; players may only purchase multiple charges of the same effect. Purchasing a separate effect charge switches the canteen over to that effect, discarding the existing effect in the process.

  • Upgraded Mad Milk slows affected enemies.
  • Upgraded Sandman marks robots for death when hit by the baseball or the bat, dealing Mini-Crits to marked robots.
    • Remember: The Scout can only mark one robot for death at a time. If the Scout marks another robot, the previously marked robot is no longer marked.

  • Instant collection of credits from robots killed by any Primary Weapon.
  • Upgraded Knife can penetrate Giants' armor, dealing extremely high damage against them.
  • Upgraded Sapper can disable groups of regular robots and slow Giants.
  • Spies' disguises fool all robot enemies; however, robots may detect a nearby backstab, and always detect a Spy who is on fire.
  • Able to reveal nearby cloaked robot Spies.

Gameplay

For the sake of identification, all human players are placed on RED team (identified as team MANNCO), while all robots use BLU colors in their visual effects and in the kill feed. Games are played in waves, each containing a pre-set number of enemies. Various support classes can also spawn in periodically until the wave is over.

When at least three players enter a Mann vs. Machine server, the option to ready up is enabled. Once one player declares they are ready, a 150-second countdown clock begins. As more players ready up, the countdown clock reduces to a minimum of 60 seconds until all players are ready. When all players are ready, the countdown reduces to 10 seconds. When the countdown ends, the wave begins. Players joining the server during the countdown do not increase the time.

Waves are constructed of a pre-set number of enemies that must be destroyed to win. A majority of waves also have "support" enemies that perform a variety of support functions. The most common supports are Snipers and Spies that spawn at set intervals throughout certain waves and generally do not drop money or go after the bomb. Other supports usually spawn continuously throughout the wave or during the last section of a wave. They usually drop a limited amount of money (so that money cannot be farmed) and also attempt to carry the bomb. While Sentry Busters are never listed as support enemies, they may appear on any wave if the team has an Engineer that reaches certain kill or damage thresholds with their Sentry Gun. If all non-support enemies are destroyed, the wave ends and all support enemies immediately die. If the support robots still had money left to drop, it is automatically collected.

Before each wave begins, the defenders are shown relevant information in the top HUD, such as the enemies the next wave contains, the current wave, and the number of waves for that mission. Pre-set enemies have a number under each icon to indicate how many are present in the wave, while support classes are listed to the right-hand side. A flashing blue icon means that the enemy or enemies always fire Critical hits. Note that typing cl_mvm_wave_status_visible_during_wave 1 into the console makes some of this information visible at all times, which can be very useful for players trying to learn a new wave.

During pre-wave intervals, Engineers are able to instantly place level 3 buildings or upgrade existing buildings by 1 level per melee hit. Medics also have a notably faster ÜberCharge fill rate, however it is still slower than the normal pre-game fill rate in the other modes.

Once the wave begins, the top HUD changes to show a strength gauge depicting the quantity of pre-set enemies left. Robots begin spawning into the battlefield in groups. Until the robots are in areas that are accessible by players, attacking one does nothing but cause it to glow as if it was ÜberCharged. During the wave, information about certain enemies may appear in the top HUD, much of which is also announced by the Administrator. Note that Snipers are not announced by the Administrator, and are instead called out by the players via automatic voice responses. These responses may also announce the presence of Tanks, Giant Robots, and Sentry Busters on the field as well.

  • Sentry Buster - Sentry Busters are large, bipedal pressure mines that run, stop, and self-destruct near Sentry Guns. If an Engineer is moving their Sentry Gun, the Sentry Buster chases them. These enemies only appear in response to effective Sentry Guns built by an Engineer on the defending team and spawn more often if there are multiple Sentry Guns. A common strategy is for the Engineer to pick up their Sentry and run away from other players on the map and touch the Sentry Buster. This causes the Sentry Buster to stop and then explode, before which the Engineer can escape with his Sentry Gun. Another common strategy is for the Engineer to sacrifice their Sentry Gun, by allowing the Sentry Buster to destroy it in a safe location. This stops the Sentry Busters targeted at that Engineer from spawning for a period of time.
  • Tank - Heavily armored tanks enter the field from specific entry points. These do not attack players directly, but move implacably towards the bomb hatch until they are either destroyed, or reach their destination. Knockback, slowing effects, and debuffs such as Marked For Death do not affect them at all. Tanks also resist 75% of Minigun damage, severely reducing a Heavy's damage output against them. Unfortunate players can be crushed if they get caught between a Tank and a solid object. Tanks do not carry or retrieve the main bomb, as each one contains its own.
  • Sniper - Sniper Robots spawn like regular robots, but mostly try to snipe players from a distance instead of running with the horde. All Sniper Robots are unable to headshot.
  • Spy - Unlike other robots, Spy Robots have custom spawn points littered throughout the map and usually spawn at the closest one to a player as long as a player is not directly looking at it. They can disguise as friendly players, backstab players, and can sap Engineer buildings (they ignore Teleporters like all other robots). The Announcer calls out to indicate when Spy Robots appear and when they have been destroyed.
  • Engineer - Engineer Robots can enter in two ways - one more common variation of the robot teleports into the map in preset locations near the bomb, while two rarer versions with a little over half of the other variation's health enter normally. Upon reaching a predetermined nest area, the Robot Engineer commences building a Teleporter, which acts as a forward spawn point for the robots (not including giant robots and robots carrying the bomb), and a Sentry Gun to defend it. The Announcer calls out when an Engineer Robot has teleported in or if one has appeared, and upon defeating an Engineer Robot the Announcer calls out that it has been destroyed, but if its teleporter is still open she says so as well.

After each successful wave, the defenders are evaluated based on how well credits were collected, with a credit rating ranging from F to A+. If all the credits are collected (the A+ grade), the defenders earn a $100 bonus. If 5% or less of the wave's total credits are missed, the defenders instead receive a $50 bonus. If over 5% of credits are not collected, the defenders receive no bonus at all.

Once a mission is completed, the defenders are given a final evaluation, and the server loads the next Mann vs. Machine map after an interval of 20 seconds. In Mann Up mode, defenders receive item drops and exit to the matchmaking lobby after an interval of 90 seconds, and this time decreases depending on how many defenders are still in the server or are finished viewing item drops.

Unused content

  • RED versions of all of the robots (besides the Tank and Sentry Buster) can be found in the game files.
  • Tan/skin colors were originally going to be used for the robots (Sniper Robot's tan head textures can be found in game files).
  • The robot mothership originally made a humming sound the first two days MvM was released, but was removed later.
  • Expired cash would have originally made a sound, but was ultimately scrapped.
  • All giants originally had their own unique footstep sounds.
  • There's an unused siren sound which is similar to an air raid siren.
  • There is an "endless" mode left over in the game that has the players fight randomly generated waves of Robots.
    • This mode can be enabled through the developer console with the command script Convars.SetValue("tf_mvm_endless_force_on", 1), through VScript, or with SourceMod plugins by setting the tf_mvm_endless_force_on server variable to 1.
    • The Robots are be able to "buy" upgrades, being allotted a certain amount of credits based on the current wave, and are limited to pre-defined sets of upgrades.[1]
    • Losing a wave resets the players to wave 1, regardless of how far they got.
    • There is very little setup time between waves, with waves going almost directly into each other.

Bugs

  • Sometimes a menu such as team, class, or upgrade choice freezes on screen, forcing the player to refresh the HUD (this can be accomplished by typing hud_reloadscheme in the console or pressing Tab ⇆).
  • When killed by a dead robot, such as by afterburn, or when removing a destroyed Spy Bot's Sapper, the kill feed may show that the robot has moved to spectator mode. This is due to an internal routine that reassigns robot players for the next attack.
  • If the TotalCount in a WaveSpawn cannot be evenly divided by the amount of robots in the WaveSpawn's Squad, the game spawns a full Squad that exceeds the TotalCount. This causes some Wave Summaries to display an incorrect amount of robots, such as wave 4 of Mannslaughter which displays 13 Medics, however the wave actually spawns 15.
  • Sometimes, after a wave is complete, the Administrator continues to issue warnings about the bomb's progress. This does not affect gameplay in any way.
  • Robots that are destroyed while speaking and players who are killed while using Mann vs. Machine-related responses continue speaking after their destruction/death. Tank Robots that are destroyed as they stop to deploy the bomb continue to play the "buzz and ding" sound sequence.
  • It is possible for the Administrator to announce that a mission has failed when it has not. This can happen when destroying the bomb carrier as it is about to drop into the bomb hole. The bomb hatch is destroyed, but the game considers the bomb undeployed. In this case, the following bomb carriers never make it to the hatch as it continues to kill anything that steps on it.
  • Sometimes, when a Mann Up mission is finished, the loot screen shows up empty. This can be fixed by entering hud_reloadscheme in the console.
    • If this occurs during server maintenance, the reloadscheme command does not work because the server was unable to return the loot. If pressing Tab ⇆ still shows tour numbers, players likely receive their loot later; however, if the tour numbers are all gone, players most likely do not receive any loot, but also do not lose their tickets.
  • There are a small number of Sentry Gun placements that are immune to Sentry Busters. If the target Sentry is in one of these areas, the Sentry Buster spawns and, without jumping down or exiting spawn, they detonate.
  • Certain sounds become stuck in a loop if a wave is failed while they are playing. A notable example of this is the Sentry Buster ticking sound. This can be fixed by typing snd_restart into the console.
  • Rarely, before the round, the bomb appears in the spawn points for the robots for all maps with no robot carrying it. An extremely rare case of this is the bomb being teleported to the hatch at the start of the round.
  • Rarely, most of the robots' voice lines may not be robotized at all. For example, the death cry of an Engineer Bot or the laugh of a Sentry Buster.
    • This can also happen if a robot speaks while far away from the player, most commonly occuring with Spy bots (with the exception of the map-wide laughter).
  • Sometimes the Robot Spy's map-wide laugh voice line is cut short (this is because the robot Spy's voice files have a second delay on them).
  • Sometimes, on Mann Up servers, a glitch occurs in which players are unable to join the server. The only way to fix this is for every player to leave the server.
  • Rarely, if an Engineer Bot's Teleporter is not destroyed by the time the wave ends, the Teleporter does not self-destruct and continue spawning robots when the next wave begins.
  • Occasionally, if a Giant Robot is destroyed with the Medic's Projectile Shield, it dies as a ragdoll rather than exploding.
    • This can also happen with any weapons that would cause ragdolls to normally be vaporized, such as the Cow Mangler 5000.
  • If a player is inspected during setup or mid-game, upgrades may be lost. If occurring during setup, money spent on the lost upgrades is refunded. If occurring mid-game, however, there is no refund on lost upgrades.
    • This happens most often with building upgrade canteens.
  • Rarely, robots may stop spawning, causing the wave to be unbeatable. This can only be fixed by restarting the map.
    • Before restarting, check around the map for a lone bot that may have wandered to the hatch. Sometimes bots head to the hatch without the bomb and delay the next sub-wave from spawning as all the other bots need to die before it can continue.
  • Sometimes, when playing two Mann Up missions in one play session, the second mission completion loot screen may show the loot screen from the previous mission and the notification for "Found Items" does not show up. Items are still obtained after updating the backpack.
    • Other times, it fixes itself after a few seconds.
  • Rarely, a human ragdoll appears rather than a robotic one.
    • This usually happens when Spy bots are killed far away from the player - for example, a Spy dying right before the player takes a teleporter from spawn would appear to have left a blue human ragdoll.
  • Very rarely, a RED Demoman's projectiles may appear to be blue instead of red when fired. Damage to enemy robots is unaffected.
  • Entering a wave that is in progress during the setup phase causes the Announcer to not say anything and no music to play. The rest of the waves play normally, however.
  • There is a random chance for an Ullapool Caber to spawn in mid-air when a Sentry Buster spawns.
    • The Caber spawns in random places around the map, and cannot be interacted with.
  • Rarely, when connecting to a server, the player is connected to a different match while still on the load screen.
    • This sometimes results in the game placing the player in an empty server with no robot waves.
  • Sometimes, the model for the Demoman robots appear as Sentry Busters. They do not possess the ability to explode, as this bug only affects the model and not its mechanics.
  • When a player readies up, their confirmation voice clip is played by every player's class, causing them to animate their faces as if they were saying the line as well.
  • Robot Spy disguises sometimes appear to have the wrong team colors on certain cosmetics.
  • Sometimes, the HUD at the top of the screen does not count the death of a Robot. The icon stays at the top, but once the last Robot is killed the wave ends.

Notes

  • Mann vs. Machine uses a separate set of "Best Moments" and thus keeps track of a separate performance report. These appear after the usual set of "Best Moments" as a client connects to a server.
  • Normal achievements cannot be obtained while playing this game mode. The only achievements obtainable in Mann vs. Machine are the Mann vs. Machievements.
  • Optionally, players can utilize .pop files to create custom waves of robots, either for practice or to create entire new missions.
  • Between waves, if a Demoman shoots stickies Crit boosted by the Kritzkrieg and the Medic switches classes, the stickies will break without exploding.

Trivia

  • Unused code suggests that players would've originally lost credits for dying during a wave.[2]
