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 on exploiters
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.

T Posing / A Posing
Under certain circumstances, the player can enter the Civilian pose.
- Scout: This can be done by equipping the Mad Milk, then suicide while holding the Mad Milk. After you respawn, hold the primary attack key, and pick up the Mad Milk you dropped when you suicided before.
- Soldier: Equip any Banner. Deal enough damage to fill the rage fully. Make sure you aren't in spawn, and change your secondary to the base jumper. Blow the banner and hold left click. While holding left click walk into the resupply cabinet.
- Pyro: Equip any flamethrower other than the phlog and kill yourself while holding it. When you respawn empty your ammo by airblasting. When you reach 0 hold right click and pick up your previous flamethrower.
- Demoman: Equip the base jumper and any stickylauncher. Walk out of spawn and equip any shield. Walk back into spawn and into the resupply cabinet while holding out the stickylauncher.
- Heavy: Kill yourself while holding out your Minigun. When you respawn empty your ammo on your Minigun and when you reach 0 keep holding down left click. Pick up your old Minigun.
- Sniper: Kill yourself while holding the Jarate. When you respawn throw the Jarate and do not release left click. While holding down left click, pick up the Jarate you dropped earlier.
- All-class: Have a friendly Engineer build a Dispenser and kill yourself either inside or next to it. When you respawn go to the Dispenser, then stand inside of it and press the action key to pick up the weapon you dropped.
- Sometimes projectiles, such as but not limited to flame particles from any flamethrower and taunt kills, can travel through the door gates used mostly on Payload maps, due to clipping issues.
- This exploit allows for instantly teleporting back to spawn without suiciding.
Fake Partner taunt
- This exploit allows for faking a partner taunt, so players attempting to accept the partner taunt will fail.
- Spamming certain commands allows for warp like effects, however you are unable to hold a warp after charging, as you immediately teleport after charging.
- Warning: This exploit may crash or hang the game for low end computers.
Reverse Quantum Crouch
- This exploit allows the player to appear standing while crouched.
- Using certain commands will freeze your client, causing your ping to increase after the game finishes freezing
- However, the real ping can still be seen by typing 'ping' into the in-game console.
- Warning: This exploit may crash or hang the game for low end computers.
Equip Conflicting Cosmetics
- This exploit allows for wearing conflicting cosmetics.
- Step 1: Join any server.
- Step 2: Unequip all of your cosmetics.
- Step 3: Equip one of the cosmetics you want to conflict in the second slot.
- Step 4: Open console (~) and type "+quickswitch"
- Step 5: Close console (~), press 6 on your keyboard and choose the second hat you want to conflict in the quickswitch menu.
- Step 6: Open console again and type: "-quickswitch"
- Step 7: Close the console.
- Note: This exploit was fixed by Valve in the September 26, 2022 Patch and reverted in the September 28, 2022 Patch.
Cloaked Spy Revealer
- This exploit uses the same method as the Warp exploit, however you do not need to move, nor do you need to spam the command (one press is enough). The Spy will appear uncloaked (but still disguised) for a fraction of a second before disappearing.
- Warning: This exploit may crash or hang the game for low end computers.
- By typing a certain command in the console before you get autobalanced, you can avoid being autobalanced and reconnect back to your original team prior to reconnecting.
- However, this command will reset all of your stats you earned before you used the command.
- Similar to warping, spamming the command used for warping allows for doubletap like effects.
- However, this exploit is not viable in-game, as you will have a fraction of a second to aim before you can doubletap.
- You will also need to stop pressing movement keys while the game is frozen, otherwise you will teleport to the location where you were holding the movement key.
Crouch Speed Boost
- While crouching, holding w and spamming a or d repeatedly will give a 33% movement boost.
- This exploit is only useful when combined with the Reverse quantum crouch exploit, or when playing as a friendly.
- This exploit allows you to votekick yourself.
- Step 1: Open console (~) and type "status"
- Step 2: Find your nickname, there should be a number before it.
- Step 3: Type in without brackets "callvote kick (your number)".
- This exploit allows for nullifying fall damage by sliding off of an edge or a ramp.
- This exploit allows for nullifying fall damage by holding crouch midair, release crouch before hitting the floor, and jump the instant you touch the floor.
- This exploit allows for bypassing certain sv_pure restrictions by loading a map with sv_pure -1 before joining a game.
- However, only certain modifications can be bypassed, such as animations.
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)
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 as well.
- 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.
- 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)
- Hiding in barrels - By standing or running into a breakable barrel while shooting at it, the player will faze through the barrel and be partly hidden. You can run out of it at any point but it requires you to redo the process to get back in it. This can also block enemy attacks until the barrel breaks.
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.
- With the Boston Basher, if the player initiates a melee attack facing an enemy within range, but does not hit the enemy after the swing has finished, the Scout will not receive any self damage.
- 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 fire 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.
- This can also be done by being inside another friendly player while shooting, and allows for you to fire at any angle.
- 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.
- An exploit using the Thermal Thruster allows the player to equip a different secondary weapon while still having the stomping damage ability and the heavily reduced fall damage attribute that is gained from the use of a jetpack charge. However, the player will be susceptible to being mini-crit by the Direct Hit whether if they are airborne or not (until death) and the distinct "flying" sound while midair from a Rocket Jumper rocket jump will continuously loop (until death or the use of the snd_restart command) due to the game still thinking they are airborne from performing the exploit.
- Under certain conditions, the Scorch Shot taunt is guarenteed to be a crit consistently.
- Performing a reverse Schrodinger's Crouch will render the player immune to Sentry Gun fire while crouching.
- However at certain angles, it is still possible for a Sentry Gun to damage you.
- 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.
- An Engineer can use a Payload cart to push himself inside his own buildings, allowing the Engineer to perform a Stucklaunch.
- A player can get an infinite Killstreak without ending an enemy Spy's Killstreak if the Spy feigns death with the Dead Ringer.
- If the Spy is near the enemy spawn, and changes his loadout, he can instantly respawn in his own spawn.
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.
- Airduct Stickies - A Demoman can shoot stickies into the airducts of either team's Basement area. Sometimes the stickies aren't completely hidden, as the space in the airducts are thin.
- 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 placed if the Engineer has the Wrangler and sentry jumps there.
- 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.
Well (Control Point) and Well (Capture the Flag)
- 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, despite it having been in the game for a long time.
- 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. Standing in the right place won't kill you, despite the Kamikaze taunt doing so elsewhere.
- 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.
- There is a rock formation between the waterfall and the small health kit that has bugged collision. You can jump inside the rock, which can allow Snipers to easily kill enemies on the point, without being sniped themselves.
- Keep in mind that bullets can still pass through the rock, so enemies can shoot you if they know you are there.
- One of the spawnroom doors isn't properly set up to disallow building.
