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 or that are not intentionally triggered are classified as glitches.

- Under certain circumstances, the player can enter the Civilian pose.
- Sometimes projectiles, namely flares, and tauntkills, can travel through the door grates used on mostly on Payload maps.
The game has a console variable
sv_pure that controls which files clients are allowed to override. By default, a server uses sv_pure 0 unless the server manager decides otherwise. This can be abused to use tampered materials that render on top of walls and other trickery.
There are four modes for the variable:
- Does not apply any rules or restrictions which files the client may load
- Applies the rules from cfg/pure_server_minimal.txt only (forcing the purity of only a few critical files such as the executables)
- Applies the rules from cfg/pure_server_full.txt and then the ones from cfg/pure_server_whitelist.txt (forcing the purity of the files chosen by the server manager)
- Applies the rules from cfg/pure_server_full.txt. (forcing all files to be pure)
Item schema manipulation
Using the same Giftapult exploit, Gamemaster1379 was able to modify the game's files by blocking the game's checks to Valve's servers, allowing him to modify/give basically anything he wanted into the game. Gamemaster1379 was able to turn any item into a stock but also the ability to give custom attributes like MaxHealth, Unusual effects, MovementSpeed and even imbued with ancient power. Gamemaster1379 was also able to change paint colors to any hex value, creating custom paints such as this. This was not only client-side, this was considered to be a legitimate item to the servers and shows as its own unique item and most likely could be traded.
This was patched in 2014.
Exploits that are present in the console version of Team Fortress 2.
Exploits that only work on specific classes.
- "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.
Building and Engineer Exploits
- An Engineer can constantly use their Teleporter to farm points, as they are awarded one half-point for every time they take their own Teleporter.
Exploits that are map specific, these can usually get players out of bounds or get into enemy spawns. Exploits that are present in the Steam version work on console aswell.
- 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_nobuildbrush stopping Engineers from building from under the spawn.
- 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.
- 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. Enemies cannot be damaged from here.
- 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.
- 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 Steam version, present in 360 and PS3 versions)
Exploits that are present in the Steam version of Team Fortress 2.
Exploits that only work on specific classes.
- With the Flying Guillotine, if the player runs towards a thin wall and throws the projectile, the projectile can go through the wall.
- After gaining a full rage meter for any banner item (Buff Banner, Battalion's Backup, or Concheror), equipping a different banner and blowing the horn while touching a resupply locker will transfer the rage to that banner.
- The Cow Mangler 5000 can be fired through thin walls. This is mostly noticeable in Thunder Mountain's spawn gates.
- The Kamikaze taunt can be used to kill enemies on the other side of a closed setup gate or a thin wall without being killed.
- The Beggar's Bazooka can be loaded to 3 rockets, and if you taunt, you store the rockets until that taunt is ended. Taunts that make a player interact (High Five!, Conga, etc.) will only let the rockets from the Beggar's Bazooka once someone interacts or the taunt is cancelled.
- 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 ignite players on the other side of the gate.
- The Flare Gun, Detonator, and Scorch Shot projectiles may sometimes be able to launch itself through thin walls if aimed at the right place
- Taunting with the Balloonibouncer in front of a wall will cause the player to submerge into the wall, causing the Pyro to be not visible or to be visible on the other side of the wall if the wall is thin enough.
- Using the Dragon's Fury you can shoot through any spawn gates.
- Sticky jumping, then crouching before you land will render the player immune to Sentry Gun fire while crouching.
- If a Heavy is stunned by a ghost, the Horseless Headless Horsemann or during humiliation while holding a melee weapon, then he can still attack via alt-fire.
- If a Heavy is changing his loadout in a loadout closet while inside the Dispenser, he is not able to attack.
Building and Engineer Exploits
- If an Engineer switches to a different Wrench while having the Gunslinger equipped, holding an undeployed Mini Sentry Gun toolbox inside of a spawn room, the player can still place down a Mini-Sentry Gun.
- Using the Short Circuit you can shoot through any spawn gates.
Exploits that are map specific, these can usually get players out of bounds or get into enemy spawns.
- A Heavy wielding an all-class melee weapon can suicide on the cart, then another Heavy wielding any kind of Glove can pick up the dropped melee weapon, resulting in the heavy dropping the gloves into the world. The model for the various forms of gloves can be placed into the cart by repetitively switching between the two weapons, until the glove model is stuck into the train, separating the platform from the train, and the head of the train keeps moving while the platform is stopped. (so long as the BLU team stays on the disconnected platform.)
- A RED Engineer can build a teleporter in the final spawnroom near the Resupply cabinet which makes it possible for BLU Spies to get into the RED spawn room.
- Snipers can shoot through a window frame near the last control point.
- Li'l Chew Chew can be glitched so that the platform will be far behind the actual engine. This lets the BLU team push the train without being near the engine.
- When the final point is capped, any BLU players who were set to respawn at that time will appear in RED's final spawn room, instead of BLU's intended final spawn room.
- Players can camp RED team's second spawn (BLU's 3rd) by using sticky bombs and firing at the top of a wall where the invisible walls cause the bombs to fall into the spawn area.
- Engineers can place buildings in the pit at the end of the map, allowing players to teleport there.
- 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. 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.
- BLU 1st Spawn
- The tall pillar of rock in the middle of the respawn wall has a small place to stand on near the top. Soldiers and Demomen can camp up here.
- The corner rock by the leftmost exit can have a sentry place if the Engineer can rocket jump and wrangle.
- Final Checkpoint
- Right before the ramp down to the final checkpoint by the map room is a small roof. Sentry Guns and Teleporters can be built on this roof.
- Between the 2 upper spawn doors in the corner above the lower spawn and health pack room is a small ledge. Sentry Guns and Teleporters can be built there.
- The Pyro was able to suicide on the final point and his flamethrower would fall through the last point and it would detonate it. This has since been patched.
- It is possible for a Pyro using any flamethrower to attack any enemies that are sitting on point A from behind the sliding steel door.
- Glitched Area - Backroom (Final Control points in
cp_welland 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.
- Infinite Kamikaze Taunt - If a Soldier goes under one of the bridges in the middle he can repeatedly perform the Kamikaze taunt without dying. This can also be used by a Medic with the Meet the Medic (taunt), potentially crashing the server.
- Taunt kill through floor - If a Soldier can get to the stairway, (the one under the health and ammo, second RED spawn) and rocket jump to a ledge, the Soldier and use the Equalizer or Escape Plan can kill players on the RED team league. And standing in the right place won't kill you using the taunt kill.
- Attacking first from last - On the path right outside the building housing the last point, it is possible to shoot over the wall into BLU's first spawn, as well as onto the path between the cart's initial position and the first point. However, this is extremely inefficient as only certain projectile weapons can achieve this alone.
- Bonk Scout - If a Scout drinks bonk and intercepts, he can still carry the ball while under the influence of bonk.
- Entering Enemy's Spawn - In the third map rotation, an Engineer can build a teleporter on the scale and let enemy Spies into the spawnroom.
