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.

General Exploits

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.

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)

Soldier Exploits

• Performing the Kamikaze taunt with the Rocket Jumper equipped to the primary slot will allow the Soldier to survive the taunt with no blast damage. (PC/Mac version only)

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)

Demoman Exploits

• If a Stickybomb is fired from the correct angle, then it can stick halfway through a thin wall and can damage players on the other side, but not cause damage on the side from which the Stickybomb was shot. (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.

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 Jarate'd. (PC/Mac version only) (Broken)

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)

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, and in rare cases, Stickybombs) to pass through the gate. This has been fixed multiple times, but seems to crop 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/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. This persists 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 - 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.

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.

• 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.

• Hiding Stickies Cap 1: If you are a RED Engineer and go to the blue exit gate on your left side, aim about a foot off the ground, count 3 cobblestones back towards the cp, 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 3 Spawn Teleporter When starting in the spawn closer to the first cap points of the track for the Payload. This is also 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

• Roof Holes: Above the RED team's 2nd respawn point, there is a large opening on the side where a BLU Demoman can spawn-kill the RED team by launching grenades into the respawn area. A BLU Soldier can also spawn-kill the RED team by launching rockets through the gap and also by rocket jumping into the gap and firing rockets directly down onto the RED team as they spawn. The BLU team's 2nd respawn area does not have this vulnerability.

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.

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.

Patched Exploits

• 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.

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

• (Patched April 30, 2010 Patch)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). (Patched; existed in PC/Mac version only)
