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

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)
• 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.
• If you shoot the ball of the Sandman at a Soldier using the Kamikaze taunt, the effect will cancel but the animation will continue. This is because the Sandman's stun takes priority over whatever action the player was doing beforehand.

Soldier Exploits

• 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 other horns (Buff Banner or Concheror) 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 thin walls, such as setup gates, and set players on the other side on fire.

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. (Xbox 360 and PS3 versions only)

• If an Engineer switches to the Jag while having a Gunslinger equipped, holding an undeployed Mini Sentry Gun toolbox inside of a spawn room, the player can still place down a Mini-Sentry Gun.

• Building a teleporter exit on a staircase and then an entrance above it will cause players to become trapped when they use the teleporter.

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. (Xbox 360 and PS3 versions only)

• Using the Crusader's Crossbow, a Medic can fire an arrow at a teammate and quickly switch to spectate with the arrow still in midair, which causes the arrow to damage the teammate when hit.

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)
• 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. (Unknown versions)

Spy Exploits

• Spies can place Sappers through thin walls, sapping buildings on the other side. (PS3 version only)
• 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. (PC/Mac version only)
  • 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. (PC/Mac version only)

Map Specific Exploits

2Fort

• Entering Enemy's Spawn In both bases, an Engineer can build a Teleporter using the hole which lets players leave the left spawn room. They must build a Sentry Gun under the hole and jump onto it, then crouch jump whilst repeatedly attempting to build a Teleporter exit inside the spawn room, which enemy Spies can use to enter the base. This exploit works as there is no func_nobuild brush stopping Engineers from building from under the spawn. (Fixed in PC/Mac version.)

• 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.)

• Holding Enemy Spawn Doors Open - Both teams can hold open the enemy's 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 is 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.

Dustbowl

Stage 1

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

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.

• 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.

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 enemy's 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.

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 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.

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 and Soldiers can jump to the top of these tall buildings and stand on the edges.

Badwater Basin

• BLU 1st Spawn
  • BLU Engineers can build in their middle left spawn door by crouching toward the corner of the door and moving around a bit. Usually two buildings can be built here, one on each side.
  • A Demoman or Soldier can Rocket/Sticky jump onto the edge of the rocks above the spawn doors from several areas in the cliffs.
  • You can also get onto the fence running down the left side from the horseshoe rock (Scouts can also do this).

• Checkpoints 2 and 3
  • Across from the roof is a small room with a medium ammo pack. It is possible for a Engineer, Soldier or Demoman to make his way up to the far right side of the roof, wait for the other team to pass, and attack, or provide his team with a Teleporter to get behind the enemy later in the round.
  • On the roof you can get onto the vents and place a Teleporter up there. An Ubercharged combo may not notice it, allowing for a easy ambush. A Soldier or Demoman can also get on the pipes above the back stairs.
  • In the side room, in the far corner to the right when entering the lower door, is some machinery. Jump onto the machine by the ammo and health packs and jump across to the left side of the machine in the corner. If you do this jump right you will be able to slowly walk across the edge until you reach the far corner in this room. Up here there are spots where an Engineer can place a Teleporter and/or Sentry Gun.

• Final Checkpoint
  • Right before the ramp down to the final checkpoint by the map room is a small roof. An Engineer, Soldier, or Demoman can use this to attack BLU as they pass.
  • In the Map room is it possible to get in top of door frames and many of the wall mounted computers to fool anybody who comes to attack you through the doors.
  • In the back area behind the Sniper tower, you can get onto the small roof between the rubber tires and the fence, this may be a good spot for offensive Engineers to set up instead of inside.
  • Between the 2 upper spawn doors in the corner above the lower spawn and health pack room is a small ledge, Several classes can jump here and set up bases or use it early in the game to attack RED as their other spawn doors open.

Gravel Pit

• 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).(Fixed in PC/Mac version)

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

• Entering Enemy's Spawn - 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. This exploit is also available in Eyeaduct.

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

Doomsday

• Sentries Under Rocket - Due to poor collision detection in the hill where the rocket is housed, Engineers may get inside of the hill and place Sentry Guns, which can shoot at enemies through walls.
