Exploits

“

I have considered an appropriate punishment for the good-for-nothings responsible for this horrendous breach of conduct. Death, of course—but death is too good for disappointments such as these. — The Administrator

”

An exploit is a bug or unintended feature of gameplay that is deliberately and knowingly used by the player to gain an advantage. For example, if a bug enables a player to be immune to damage and a player knowingly uses it, it is an exploit. In contrast, bugs or problems which either do not affect gameplay that are not intentionally triggered are classified under glitch.

NOTE: An exploit is said to be broken if it is unintentional to the game's developers, because it is a broken feature of the game.

General Exploits

By Class

Scout Exploits

• Moving towards a wall then hitting the Sandman ball right before hitting the wall may send the ball through it, hitting unsuspecting players on the other side. (PC/Mac version only)
• Splashing Mad Milk on the ground outside a setup gate will sometimes cause players on the other side next to the gate to be Mad Milked. (PC/Mac version only) (Broken)
• Because the invulnerability timer for Bonk! Atomic Punch is client-side, freezing or slowing down the game after drinking it will prolong the effects. This also applies to temporarily losing connection to the server.

Soldier Exploits

• Performing the Kamikaze taunt next to a thin wall when standing in correct angle will sometimes cause the blast to kill targets behind the wall. (PC/Mac version only)
• After gaining a full rage meter for any banner item, equipping a different banner and blowing the horn while touching a resupply locker will transfer the rage to that banner.
• Taking damage from staying underwater for too long will fill the rage meter for the Battalion's Backup. This can be exploited to gain free buffs for any of the horns using the banner switch exploit.

Pyro Exploits

• Using any of the flamethrowers and firing in a downwards position will sometimes cause flame particles to go through walls, such as setup gates, and set players on the other side on fire. (Broken)

Engineer Exploits

Building Exploits

• An Engineer can constantly use their Teleporter to farm points, as they are awarded one half-point for every time someone takes their Teleporter. (Fixed in PC/Mac version, broken in Xbox 360 and PS3 versions)

• Through specific placement of the Teleporter, players can become stuck instead of teleporting. However, this can be avoided by crouching while being teleported.
• When players get stuck in Teleporters, any knockback or momentum they receive will be stored and released when they become unstuck. This can be used to perform massive jumps. In addition, the knockback will be passed onto enemy players who are on top of the stuck player and will launch them in the same way.

Medic Exploits

• "Needle Boosting" involves a player standing over a Medic, who then proceeds to shoot their Syringe Gun upward as the player jumps. Due to a physics error, the Medic's Syringe Gun needles propel the target upward. (Fixed in PC/Mac version, broken in Xbox 360 and PS3 versions)

Sniper Exploits

• Splashing Jarate on the ground outside a setup gate will sometimes cause players on the other side next to the gate to be Jarated. (PC/Mac version only) (Broken)
• Switching weapons quickly after taking a shot with the Sniper Rifle will result in a faster rate of fire, since the reload animation will not occur.(PC/Mac version fixed, others unknown)
• Switching weapons quickly when charging the Huntsman will prepare it for another shot faster than cancelling with alt-fire.

Spy Exploits

• Spies can place Sappers through thin walls, sapping buildings on the other side. (Fixed in PC/Mac and Xbox 360 versions, broken in PS3 version)
• If a Spy backstabs an enemy and picks up the Intelligence at roughly the same time, the Spy can still use the Disguise Kit while holding the Intelligence. (Present in the PC version)
  • If a Spy backstabs an enemy and picks up the intelligence at the same time with Your Eternal Reward, the Spy will disguise as the target while holding intelligence. (Present in the PC version)

Terrain Exploits

• On certain maps, Engineers can place Sentry Guns and other buildables behind chain-link fences, from behind which it can shoot at the enemy team. The buildables can still generally be sapped or affected by explosive splash damage. (Broken)

• The spawn gates allow certain weapons (the Flamethrower, Jarate, Mad Milk, sandman's baseball, and in rare cases, Stickybombs) to pass through the gate. This has been fixed multiple times, but seems to pop up every once in a while.

• In certain maps, it is possible for a Demoman to Sticky Jump high enough in certain areas to bypass the invisible wall over a map, allowing him to run across the sky and fire down at enemies.

• Very rarely, an Engineer can use an exploit to pass under the floor of a map and build Sentry Guns underneath it, allowing it to shoot upward at targets without fear of destruction. This is considered to be griefing and will likely result in administrative action on many servers.

Map Specific Exploits

2Fort

• Entering Enemy's Spawn 1 The Engineer can build a Teleporter exit in their spawn. After the Sniper vs. Spy Update (which allows Spies to take enemy Teleporters), it's possible to enter the enemy's spawn with an enemy Engineer. You must be a Spy to use the teleporter/enter the enemy's spawn. This is currently unpatched.

• Entering Enemy's Spawn 2 A hole in the lower, right side of the No Enter symbol for BLU's base (the one next to the haystacks) can be used by RED players to get into the BLU spawn room. (Present in the Xbox 360 and PS3 versions.)

• Entering Enemy's Spawn 3 In the BLU base if an Engineer crouch jumps beside a plank below the spawn, they will go through the map. If they are able to construct a building in this area, the Engineer can then build a Teleporter inside allowing other players to enter.

• Opening Safe Room's Door - It is possible to open the door leading into the "Safe Room" in which you first respawn, by jump-crouching into the door's handles and jump-crouching again to reach the top of the door, and it will then open. (Fixed in the PC/Mac version) Note: This can only be done in the BLU main Respawn area and may sometimes not open.

• Holding Enemy Spawn Doors Open - Both teams can hold open the enemies spawn door at the hay room by running into it while it is open. While this works well for the BLU team (as they can potentially spawn camp), it's not so easy for the RED team. Should a member of the RED team attempt this, there is a chance for the player to get stuck in the door, unable to move, and end up getting dragged up and down with the door as the BLU team enters and leaves the spawn area.

• Pointless Room - There is a spot in each Intelligence room, where a player can get other players stuck. This a dead-end, because players cannot escape, unless they suicide. By building a Dispenser on the left wall of the left corridor (the one facing the Intelligence) and then by using the "jump through roofs" exploits to build a Teleporter exit, a player can trap other players on their team. There is no tactical advantage to getting in here (Sentry Guns don't work here either), you can't be shot or shoot anybody. It is mostly used by people who are griefing as they will set up a Teleporter entrance somewhere in your base and an exit in the roof. This then traps your team-mates and forces them to commit suicide. (Fixed in PC/Mac version, broken in 360 and PS3 versions)

• Roof Holes - A hole in the roof of the BLU team's 'upstairs' room (above and behind the balcony) allows arcing projectiles (grenades and needles) to be fired into the 'upstairs' room just outside the BLU team's main respawn room. It can be used for taking out Sentry Guns placed in the corner of the 'upstairs' room. This looks intentional; however the same cannot be used on the RED team's base as chicken wire covers the hole. (Fixed in PC/Mac version, broken in 360 and PS3 versions)

Badlands

• The RED Spawn - The RED team's initial spawn room has misplaced no-entry blocks allowing members of the BLU team to sneak in.

• Center Spawn Areas - An Engineer can build in the center spawn areas (once the fourth point is captured). You have to crouch to be able to build.

• Last Point - It is possible to capture/block a capture from the outside of the cap.

• There are many vents in the ceiling at the final points that provide small hidden areas for spawn camping or defense

Dustbowl

Stage 1

• Starting Gates - During the set-up time a Demoman can bounce pipe bombs through the gates to the BLU spawn. (Fixed in PC/Mac versions)

• Building Inside Spawn - In the BLU team's spawn area an Engineer can build right in front of the gate on the left, and in a corner off by the gate on the right.

• Skywalking 1 - Cap 2. Engineers can build Dispensers/Sentry Guns to stand on (or can jump on top of nearby boxes), and are then able to access higher areas. To skywalk, a player must go to a specific small room with boxes (the one across the bridge), and then crouch jump to be able to place a Teleporter exit. Then by building a Dispenser next to the wall and building another teleporter exit on top of the wall, the player is able to skywalk at Cap 2 Stage 1 Dustbowl. They are also able to build Sentry Guns on top of the room with the box. (Fixed in PC/Mac versions)

• Infiltrating the Protected Tunnel - The 'secondary' entrance to the tunnel protected by a one-way door (from RED's perspective) is on a ledge just a short distance away from the door, but is generally only accessible if playing as a Scout, Soldier or Demoman, who can jump/blast their way onto the ledge. However, any class can reach the ledge from the outside due to the presence of several solid bolts and planks against the wall which can be stood upon.

Stage 2

• Healing Through Walls - By building your Dispenser inside the small house next to the first capture point you are able to get metal and heal yourself. To do this, a player simply builds a Dispenser as close as possible to the wall with the telephone, and must then go onto the other side to see if they have built it close enough.

• Skywalking - Cap 2. To do this, simply build your Dispenser onto of the farthest section of stage 2, capture point 2 from the cap. And then get yourself glitched, by crouching and then jumping, then have a Medic needle boost you to build your teleporter. (Fixed in PC/Mac version, broken in Xbox 360 and PS3 versions)

• Teleporters Above Ground - To do this, go to the small house that is next to the first capture point of stage 2. Then go to the sections with either a telephone on the desk, or a coffee machine on the desk. By standing on this, you are able to build your Teleporters on top of the desk. You might have to shift around or jump to get this to work.

• Teleporter Inside RED Spawn - By crouching while next to the side of the walls, you are able to build your teleporter, Sentry Gun, or Dispenser in your spawn or the enemies spawn.

• Return to Stage 1 - BLU Spawn - Allows you to move back to the first stage of Dustbowl. This requires an Engineer and a Medic. Let the Engineer go to the LEFT supply locker of BLU, then get glitched by crouching then jumping. Now, the Medic needs to needle boost him to the top of the locker, then the Engineer needs to build an exit on the roof. Teleport, and you will be behind the fence that is blocking stage 1. Combine this with Stage 1 Skywalk, and you will be able to skywalk above your spawn, and defend it from above.

Stage 3

• Teleporter Inside BLU Spawn - By crouching, while next to the side of the walls, you are able to build your teleporter, Sentry Gun, or Dispenser in your spawn or the enemies spawn.

• Hiding Stickies - Cap 1: If you are a RED Demoman and go to the blue exit gate on your left side, aim about a foot off the ground, count 3 cobblestones back towards the capture point, and you can shoot stickies into the wall. Here they cannot be seen aside from a mute red light which goes away.

• Skywalking - Cap 2: You will need an Engineer and a Medic for this. From RED's spawn, walk forward, until you will see a staircase to your RIGHT (not the one who leads down, but the one who leads UP). Climb it, and walk all the way, until you see an exit to your RIGHT. Build a Dispenser there (make sure it won't be under the roof), and climb on it. Take out a Teleporter Exit, and let the Medic needle boost you, while you hold "Build" button. If done correctly, you will build the exit at the sky. Now, refill your metal supply, build a teleporter entrance, and teleport. You will notice you cannot move. Destroy the Exit, and build it again somewhere around you. Now suicide (Switch to another class then back to Engineer), and teleport. You are now skywalking. Be careful not to go out of the map's bounds, or you will fall down to the ground and stay stuck there unless you suicide. (Fixed in PC/Mac version, broken in Xbox 360 and PS3 versions)

Gold Rush

• Stage 1 - Engineers can build on the balcony just before the final cap point.

• Stage 1 - Certain projectiles can be fired through the start-up gates.

• Stage 1 - After the first point is captured, if someone on the RED team stands on the pile of tires in the room near the Payload tracks, it will block the enemy team's capture.

• Stage 3 Teleporter in Spawn - When starting in the spawn closer to the first cap points of the track (The spawn with the large staircase), you are able to build your Teleporter inside your spawn by standing sideways to the gate.

• Spawn Exploit - In some of the spawns there are holes in the middle of the ceiling that Demomen and Soldiers can jump up into. This doesn't really have any practical use except for avoiding death in Humiliation.

Granary

• RED 2nd Respawn -A ledge on the edge of the respawn room can be accessed by Soldiers, Demomen and Engineers by jumping towards the opening in the top of the spawn from outside. It is possible for BLU players to spawn-kill from there. Engineers can sentry jump into this spot and then place Teleporters into the small area over the air near the grain chute. Players will be skywalking in this small area and can directly enter the RED spawn as any class by dropping down. Sentry Guns can be built here to target REDs as soon as they spawn. RED Soldiers and Demomen can also jump into the area from inside the spawn.
  • The small roof above the grain chute next to the spawn can also be accessed and built on
  • In the yard near the spawn there are tall, round structures and a small shack. Demomen can sticky jump to the top of these tall buildings and stand on the edges.

Gravel Pit

• Roof Holes - A hole in the roof of RED's respawn room allows weapon fire in both directions. The holes are between the boards over the window and big enough to allow most projectiles through.

• Spawn Building - RED Engineers can build inside their spawn area by crouching on the office chair and facing the computer panel to its right. Once the vertical position of the blueprint changes to match the visible height of the panel (which only occurs in a particular spot), the Engineer can place their construction at a specific mid-air point (this essentially means repeatedly jumping while spamming the keys bound to Crouch and Primary Fire).

• Under Map 1 - Cap A. - By using the "Crouch Jump" exploit, you can get under the map at Gravel Pit Cap A. To do this, go to the tunnel next to Cap A. Build a Dispenser and use the "Crouch Jump" exploit to build a teleporter exit. After using the teleporter you built, you will need to crouch jump over a little gap in the small room you teleported into and you will be able to build Sentry Guns under the map.

• Under Map 2 - Cap B. - By using the "Jump through Walls" exploit, you can get under Cap B Gravel Pit. Go to the area, with the ramp, and then jump through the wall next to it.

Hydro

• Skywalking is possible in one spot with the help of someone from the other team. To do this, simply have a Spy or Scout on the other team crouch jump on to your Dispenser, and then have them move over to one side of it, while you get on it. Then while they are crouched, crouch jump on top of them. Then have them stand up, and both of you crouch jump to get yourself on top of the lamp next to the door. Then try to crouch jump over to the spot where the teleporter was built, and try to build it there while you are jumping. Another way would be to have a Demoman or Soldier shoot at your feet to boost you up to the top of the lamp.

Steel

• BLU Spawn - Jumping above the BLU teams exit door to B before the round starts can cause the door to get stuck, making BLU team not able to leave through the B exit door.
• It is possible for a Pyro using the Backburner to attack any enemies that are sitting on point A from behind the sliding steel door.
• RED Engineers can build Teleporters inside the first spawn in the corners of the door to Point A
• There is a tiny ledge at the very back of the small wooden balcony at Point B that can be stood on. The rest of the balcony is not solid and will not hold players, however it provides cover for Demomen and Soldiers that can still shoot through it without being seen.

Viaduct

• There is a way to place a teleporter inside the respawn. An Engineer should build a sentry near to the respawn and upgrade it to third level. When it is ready, an another player should be holding the door. Engineer should rocketjump using a Wrangler to the upper platform of the room. There he can easily place a teleporter, and make his respawn easily accessed by enemy Spies.

Well

• Glitched Area - Backroom (Final Control points in CP_Well and Intelligence room in CTF_Well) - Allows Soldiers, Demomen, and Engineers to get into the roof area and on the beams. It is unconfirmed if this is an exploit or not as both teams can use it, higher areas are blocked by invisible walls and this hasn't been fixed by Valve even though it's been around a while.
• Demomen can sticky jump over the invisible walls in the middle of ctf_well to get out of the map or skywalk

Patched Exploits

• Backstab Not Breaking Disguise - Whereby a Spy could backstab while retaining their disguise (Fixed in PC/Mac and 360 versions, broken in PS3 version).

• Bunny Hopping (Patched October 31, 2007) - A jumping technique that allowed players to move faster than they should by bypassing the velocity cap. (Fixed in PC/Mac versions, unknown in 360 and PS3 versions)

• Reference Pose Heavy - Whereby a Heavy could go into a reference pose by spinning the Minigun in spawn and switching class to Heavy. This is still performable, but another method is required. (Fixed in PC/Mac and 360 versions, unknown in PS3 version).

• Permanent ÜberCharge

• Whereby a disconnected Medic could continue to ÜberCharge his target indefinitely.
• Whereby a Medic is able to give himself an ever-lasting ÜberCharge for the rest of the round. It requires a player to have unlocked the Kritzkrieg, and is done by switching to the Kritzkrieg whilst deploying the Über in the team respawn room. This can also be done the opposite way around - by switching to the Medi Gun, giving the player infinite Critical hits for the rest of the round. Standing near a Dispenser (or Payload while attacking), healing a team-mate, or being healed by a team-mate will however end the charge.

• Permanent Bonk - Where a Scout becomes permanently under the effect of Bonk! Atomic Punch by drinking the item while moving into a supply cabinet. (Fixed; existed in PC/Mac version only)

• Level 3 Combat Mini-Sentry Exploit - Whereby an Engineer could build a Combat Mini-Sentry that fires rockets by building a Level 3 Sentry Gun, switching to Gunslinger (either by respawning or using resupply lockers), then re-deploying the Sentry Gun. The resulted Sentry Gun would take only 2.5 seconds to build like a Combat Mini-Sentry, but fired rockets like a normal Sentry Gun. (Fixed; existed in PC/Mac version only)

• Multiple Buildings Exploit - Several methods where the Engineer (or in some cases the Spy) could build multiple copies of all his buildings.

• Whereby an Engineer can build an unlimited number of buildings by using the commands, "build 0 x", "build 1 x", and "build 2 x" (where x is the number of the building), and a Spy can build an unlimited number of Dispensers using "build 0 x" (where x is the number of the building). (Fixed April 30, 2010 Patch; existed in PC/Mac version only)

• An Engineer could pick up a building with the "Automatically respawn after loadout changes in respawn zones" option and change their loadout hereby glitching them into having a building being "carried" and allowing the Engineer to build multiple buildings using the "build x" commands. (Fixed October 18, 2010 Patch; existed in PC/Mac version only)

• Invisible Buildings Exploit - Any Engineer picking up a building and immediately taunting would would be able to use the weapon they taunted with whilst holding this building.
