This page is about bots in the game Team Fortress 2. For bots on the Team Fortress Wiki, see Category:User bots.

“

Human teammates might judge you, but will these soulless automatons? YES. They're not blind. But they ARE mute, so your incompetence is a secret they will take to their grave. — Mac Update blurb

”

There are two types of bots in Team Fortress 2: AI bots and Puppet bots. AI bots are coded with sophisticated artificial intelligence designed to emulate player actions in game, and can be used without enabling cheats. Puppet bots have no AI coding, but are useful for testing and training. Puppet bots require the server to have cheats enabled, which also disables achievements.

AI bots

AI bots are designed to emulate human players and are not directly controlled. Additionally, their classes are chosen at random. They use sophisticated AI code based on the PlayerBot and Infected AI featured in the Left 4 Dead series. AI bots do not require the server to have cheats enabled, therefore, achievements are enabled while playing with them with one exception: Bots never see Deathcam shots when you kill them; therefore, you cannot attain Deathcam taunt achievements against a bot.

AI bots can be indirectly controlled to an extent:

• Any friendly and enemy bot that the player focuses on with their crosshair during setup time will taunt.
• A Medic bot will heal a player if they utilize the "Medic!" voice command.
• If a Medic bot is healing and has an ÜberCharge ready, using the voice commands, "Go go go!" or "Activate Charge!" will cause the bot to activate his ÜberCharge.

Bots will use voice commands such as "Spy!" and "Move Up!", but text versions of these voice commands do not display.

Current AI bot status

AI bots are in beta testing and will become more sophisticated as they are updated. Currently, all classes are working properly due to the Hatless Update, including the once-buggy Spy. AI bots only work properly for most official King of the Hill maps, some Payload maps, Attack/Defend maps Dustbowl and Gorge, Capture the Flag maps, and Mann Manor (on the latter two, bots can only be added by using the tf_bot_add command). The use of AI bots on non-supported maps is possible by following certain steps; however, they will not emulate human players as well.

Note: A pack of pre-made bot meshes has been compiled for many popular maps.

AI bot names

The AI bots are programmed to have different names, with many of their names being references to Valve's other works and computer programming. They also include some references to Team Fortress as well. Many of these names have been requested on the Steam forums.

Using bots on unsupported maps

1. Type "sv_cheats 1" in console
2. Type "nav_generate" in console
3. Wait while the game generates AI paths
4. Map will reload (navigation has been saved and the previous step doesn't need to be repeated)
5. Open console and type "tf_bot_add <number>" as above to add bots
6. Revert "sv_cheats" to 0 afterwards (optional, but if it is not done, then achievements will be disabled).

Bots can be used on any map on which the above steps have been performed without having to repeat them, except for entering the "tf_bot_add <number>" command each time bots need to be added.

Maps with official bot support

• Dustbowl
• Mann Manor
• Badlands (KOTH)
• Lakeside
• Nucleus (KOTH)
• Sawmill (KOTH)
• Viaduct
• Badwater Basin
• Gold Rush
• Hoodoo
• Thunder Mountain
• Upward
• Gorge
• Barnblitz

AI bot behavior

• Bots currently can not use or equip most unlockable content including most non-standard weapons, hats, or Miscellaneous items.
• Bots on Easy difficulty will rarely, if ever, use any weapon other than their Primary weapon.
• Bots currently can not rocket jump or sticky jump.
• If a bot kills a player, they roll a chance to taunt immediately after, and if it succeeds, they will taunt even if they are under enemy fire.
• Spy bots (and players) are properly ignored by other bots while disguised. However, upon 'touching' any enemy bot, sapping, shooting, or cloaking, all other bots who see it happen will declare the bot/player a Spy and won't forget who they are until they morph again or until the bot(s) who declare them a Spy die.
• Pyro bots will use the compression blast against projectiles and opponents regularly if on difficulties other than Easy.
• Medic bots will usually heal all other classes before Snipers (and to a lesser extent Engineers) even if the "Medic!" voice command is used.
• Spy and Sniper bots currently do not appear on Easy mode: they will only appear on Normal mode and beyond.
• If a disguised Spy bot on expert sees you Cloak, he will be able to follow you while you are invisible regardless of if your Cloak is blinking or not.

AI bot commands

To use AI bots on supported maps, the server administrator should type the following commands into the console:

Command	Description
tf_bot_add	This command will create one or more AI bots of random classes on random teams. They will also be assigned amusing human-like names. Syntax tf_bot_add [<count>] [<class>] [<team>] [<difficulty>] Parameters <count> Specifies the number of bots to spawn. If omitted, one bot is spawned. As of this writing, specifying a number greater than the maximum number of players, including any human players, causes the bots to freeze. Thus if there is a 24 player server (the default), and one human player, do not spawn more than 23 bots. <class> The classname of the class can be Demoman, Engineer, HeavyWeapons, Medic, Pyro, Scout, Soldier, Sniper, or Spy <team> Specifies the team name to assign the bot, where team can be red or blue. <difficulty> Sets the difficulty level for the bot, where difficulty can be easy, normal, or hard. Example tf_bot_add red 3 heavyweapons easy will add three Heavies to the RED team at the easy skill level.
tf_bot_difficulty	Defines the skill of bots joining the game. Syntax tf_bot_difficulty <level> Parameters <level> Sets the difficulty level for the bots. Values are: 0=easy, 1=normal, 2=hard, 3=expert. Default is "Normal" (1). Example tf_bot_difficulty 2 will set all bots created after this command to "Hard" difficulty.
tf_bot_force_class	If set to a class name, all TFBots will respawn as that class. Syntax tf_bot_force_class <class> Parameters <class> The classname of the class can be Demoman, Engineer, HeavyWeapons, Medic, Pyro, Scout, Soldier, Sniper, or Spy. Default is "" (aka blank). Example tf_bot_force_class medic will make all TFbots respawn as Medic.
tf_bot_join_after_player	If nonzero, bots wait until a player joins before entering the game. Syntax tf_bot_join_after_player <integer> Parameters <integer> Either 1 or 0. Default is 1 (enabled). Example tf_bot_join_after_player 0 will make TFBots join the game when added even if no players are on a team.
tf_bot_keep_class_after_death	If zero, bots will always respawn as a different class. Syntax tf_bot_keep_class_after_death <integer> Parameters <integer> Either 1 or 0. Default is 0 (disabled). Example tf_bot_keep_class_after_death 1 will prevent TFBots from changing class.
tf_bot_kick	This command will remove one or all AI bots. Syntax tf_bot_kick <name/all> Parameters <name/all> Specifies the name of bot to remove or all. Example tf_bot_kick CEDA will kick the TFbot named "CEDA" if one exists.
tf_bot_prefix_name_with_difficulty	If nonzero, append the skill level of the bot to the bot's name Syntax tf_bot_prefix_name_with_difficulty <integer> Parameters <integer> Either 1 or 0. Default is 0 (disabled). Example tf_bot_prefix_name_with_difficulty 1 will cause added bots to have names like "1 Aimbot" (normal) and "3 Saxton Hale" (expert).
tf_bot_quota	Determines the total number of TFBots in the game. Only has effect if "tf_bot_quota_mode" = "fill" or "match". Syntax tf_bot_quota <integer> Parameters <integer> Whole number between 0 and how many players the server can hold. Default is 0. Example tf_bot_quota 2, if tf_bot_quota_mode = match, will add two bots to the server for every one human.
tf_bot_quota_mode	Determines the type of quota. Syntax tf_bot_quota_mode<normal/fill/match> Parameters normal/fill/match If 'normal', the server will never add/remove TFbots without explicit commands and bot_quota has no effect. If 'fill', the server will adjust bots to keep N players in the game, where N is bot_quota. If 'match', the server will maintain a 1:N ratio of humans to bots, where N is bot_quota. Example tf_bot_quota_mode fill will always keep (bot_quota - # of human players) bots in the game.
tf_bot_taunt_victim_chance	Determines how often a Bot will taunt a human victim. Syntax tf_bot_taunt_victim_chance <integer> Parameters <integer> Whole number between 0 and 100. Default is 20. Examples tf_bot_taunt_victim_chance 0 Bots will never taunt when killing a human player. tf_bot_tauntvictim_chance 100 Bots will always taunt when killing a human player.
tf_bot_melee_only	Determines whether a bot should only use Melee weapons or not. Syntax tf_bot_melee_only <integer> Parameters <integer> Either 1 or 0. Default is 0 (disabled). Exmaple tf_bot_melee_only 1 will have bots using only Melee weapons.

Puppet bots

Puppet bots have no AI code and cannot move or act on their own. These bots can be used like puppets though, players can manipulate them to follow the player's commands such as following the player around and firing their weapons. Puppet bots are mainly used for testing purposes and can also create stunning visuals if manipulated accordingly, as seen here.

Puppet bot commands

Not all of the following commands work; for clarity, the complete list of commands is included.

Note: entering the command without any values will display the command's current setting and a brief description.

Command	Description
bot	This command will create a bot on the given team with the specified class and name. If team or name is omitted, they will be assigned randomly. Syntax bot -team <teamname/number> -class <classname> -name <botname> Parameters -team teamname/number Specifies the team name or number to assign the bot. Where name/number can be RED or 1, BLU or 0 -class classname The classname of the class can be Demoman, Engineer, Heavy, Medic, Pyro, Scout, Soldier, Sniper, or Spy -name botname botname can be anything. If there is already someone with the same name, an incremental number (starting at 1) surrounded with parenthesis will be added to the beginning of the name. For example, joe, (1)joe, (2)joe, etc. If no name is given then the name will be "bot" followed by a number starting with 01; for example, the first bot will be bot01, the next bot02, and so on. Example bot -team red -class Engineer -name joe
bot_changeclass	Force all bots to change to the specified class. Does not seem to be implemented, nothing happens.
bot_changeteams	Make all bots change teams. This forces all the bots to switch teams. If a bot was on the RED team then it will now be on the BLU team and vice versa.
bot_command	Sends specified command on behalf of specified bot. Syntax bot_command <botname> <console command> botname is the name or id of the bot to send the command to. console command can be any of the ones listed in Scripting#Console Commands. Example 1 bot_command bot01 "voicemenu 0 0" Example 2 bot_command bot01 "taunt" The slot commands (slot1, slot2, etc.) do not work with bot_command, however with bot_forcefireweapon, all bots in that class can be made to switch to a weapon and start firing, then made to stop. Only the entire group of bots in that class can be made to do so, however.
bot_defend	Set to a team number, and that team will all keep their combat shields raised. For instance, Heavies will spin their miniguns.
bot_dontmove	Bots are allowed or prevented from moving. When set to 1 the bots cannot move but they can still turn and jump. Note with a combination of this command and bot_mimic bots can be moved to certain areas and left there. Syntax bot_dontmove <0/1> Bot is allowed to move, or not. Example bot_dontmove 1
bot_flipout	When on, this command will make the bots fire the current weapon selected. Default is to use primary_fire, but if bot_forceattack2 is set to 1 then secondary fire is used. Syntax bot_flipout <0/1> On when set to 1. Off when set to 0. Example bot_flipout 1
bot_forceattack	This will make all the bots automatically fire whatever weapon they currently have selected. If bot_forceattack2 is set to 0, then the bots will execute primary_fire. If bot_forceattack2 is set to 1, then the bots will execute secondary_fire. Note this does nothing if bot_mimic is active (set to 1). Syntax bot_forceattack <0/1> Bot will not fire if set to 0 and fire repeatedly if set to 1. Example bot_forceattack 1
bot_forceattack2	This will make all the bots execute secondary_fire on whatever weapon they currently have selected when bot_forceattack is set to 1. Syntax bot_forceattack2 <0/1> Bot will use its weapon's secondary_fire when set to 1, primary_fire when set to 0 Example bot_forceattack2 1
bot_forceattackon	When firing, do not tap fire, hold it down. When this command is set to 0, the bot acts like it is continuously tapping the fire button (useful for the Pistol, but not for the Heavy's Minigun). If this command is set to 1, the bots acts as if it is holding down the fire button (useful for the Heavy's Minigun). Syntax bot_forceattackon <0/1> On when set to 1. Off when set to 0. Example bot_forceattackon 1
bot_forceattack_down	When firing, don't tap fire, hold it down. If this is set to 0 then the bot will act like they are continuously tapping the fire button (useful for the Stickybomb Launcher). If this is set to 1 then the bot will act as if it is holding down the fire button (useful for the Minigun). Syntax bot_forceattack_down <0/1> On when set to 1, off when set to 0 Example bot_forceattack_down 1
bot_forcefireweapon	Forces all bots who have the specified weapon to switch to and fire it. If a bot does not have this weapon, nothing happens to it (unless it is firing a different weapon, in which it stops) Syntax bot_forcefireweapon <weapon filename> filename is usually tf_weapon_ <weapon name>. Examples bot_forcefireweapon tf_weapon_fists makes all Heavy bots switch to and repeatedly attack with their Fists, and all other bots stop attacking. bot_forcefireweapon tf_weapon_shotgun_pyro makes all Pyro bots switch to and repeatedly fire their Shotguns, and all other bots stop attacking. To make all bots stop attacking, simply specify a non-existent weapon filename. Anything without tf_weapon in it isn't a TF2 weapon, so the bots won't shoot it, for example bot_forcefireweapon ,, Bots' loadouts cannot be changed, therefore you cannot make them fire unlockable weapons.
bot_kill	Kills the specified bot. Syntax bot_kill <bot name> Makes the specified bot commit suicide. Example bot_kill bot01
bot_mimic	Bot uses usercmd of player by index. The bot will execute all keystrokes issued by a player, mimicking movements, turns, jumps, fire, etc. It should be noted that bots will not mimic Medic calls, weapon switches, or taunts. Note this overrides bot_forceattack but does not override bot_dontmove. Syntax bot_mimic <0/1> On when set to 1, off when set to 0 Example bot_mimic 1
bot_mimic_inverse	Inverts the movement of the bots; moving left makes the bots move right, moving forwards makes the bots move backwards, etc. The direction which the bot is looking is not affected. Syntax bot_mimic_inverse <0/1> On when set to 1, off when set to 0 Example bot_mimic_inverse 1
bot_mimic_yaw_offset	Offsets the bots' yaw. The bots will face in a direction this angle from the player. By default this is set to 180 so that all bots will face the player. Setting this to 0 will face the bots in the same direction as the player. Syntax bot_mimic_yaw_offset <0-360> Set the direction by specifying angle in degrees Example bot_mimic_yaw_offset 180
bot_randomnames	Syntax bot_randomnames <0/1> On when set to 1, off when set to 0 Example bot_randomnames 1
bot_refill	Refills all bots' Ammo counts, including Metal for Engineers. Syntax: bot_refill
bot_saveme	This makes all the bots call for a Medic, equivalent to issuing bot_command <botname> "voicemenu 0 0" to every bot. Syntax: bot_saveme <0/1> On when set to 1, off when set to 0
bot_selectweaponslot	This makes the first bot select weapon in specified weapon slot. 0 = primary; 1 = secondary; 2 = melee; 3 = special Note this only works for the first bot spawned. There doesn't seem to be a way to specify other bots. Syntax bot_selectweaponslot <n> Set n to weapon slot that bots should switch to. Example bot_selectweaponslot 2
bot_teleport	Teleports a specified bot to a given coordinate. Map coordinates of where you are standing can be found by typing Status in the console. Syntax bot_teleport <botname> <X> <Y> <Z> <Pitch> <Yaw> <Roll> Where botname is the bot name or id to teleport. X Y Z are the map coordinates. Pitch Yaw Roll is the direction the bot should face. Example bot_teleport bot01 -4815 1385 -447 0 0 0
bot_whack	Delivers lethal damage from player to specified bot. This basically kills the bot with the currently selected weapon, probably used for testing during development. Syntax bot_whack <botname> Where botname is the name of bot to "whack". Example bot_whack bot109

Update history

December 17, 2009 Patch (WAR! Update)

• Added work-in-progress Bots for beta testing in KOTH maps.

January 6, 2010 Patch

• Various improvements to combat behaviors.
• In KOTH mode, Bots are now:
  • More likely to roam around and hunt enemies if there is lots of time left.
  • Become more likely to push for the point as time runs down, or their teammates start to capture it.
• Medic bots now:
  • Opportunistically "overheal" nearby friends when they can.
  • Prioritize healing of injured nearby friends more.
  • Don't focus on Heavies quite so exclusively.
  • Don't spam their Medi Gun continuously at round start.
  • Won't choose cover far below their heal target so much (koth_nucleus).
  • Fight back with their Syringe Gun appropriately.
• General bot improvements:
  • They no longer stand still on the point when capturing or defending it.
  • They choose more varied routes now.
  • They choose better defensive spots around captured points.
  • They fall back to another weapon when they entirely run out of ammo.
  • They adjust their FOV when using zoomed in Sniper scope.
  • They treat in-range Sentry Guns as the most dangerous threat.
  • They fire their weapons is more realistic bursts.
  • Engineers use their Shotgun properly.
• Added a "virtual mousepad" concept to rework how bots track enemy players.
  • They now periodically estimate the position and velocity of the enemy they are tracking, instead of "locking on".
  • Addresses the "180 spin around and fire", "Heavy bot is OP", "Sniper bot is OP", and "I can't fight a Heavy bot as a Scout" issues.
• Tuned Sniper spot finding algorithm to generate more diverse locations, partially .addressing the "Predictable Sniper camping spots" issue.
• Soldier bots are more careful to not fire rockets that will explode on nearby geometry and kill them.

July 19, 2010 Patch

• Improved performance of bot computations that are done when a point is captured, a round starts, or a checkpoint reached.
• Fixed Engineer bots infinite build-destroy behavior loop regression.
• Fixed Medic bots losing their charge if they touch a resupply cabinet.

May 5, 2011 Patch (Replay Update)

• [Undocumented] Bots now properly target the Horseless Headless Horsemann as an enemy.

July 22, 2011 Patch

• [Undocumented] Bots now work on CTF maps.

July 26, 2011 Patch

• Fixed a rare crash bug with the Demoman TFBot laying stickybomb traps

August 23, 2011 Patch

• Fixed crash with Demoman* bots trying to detonate stickybombs that had already been destroyed
• Added tf_bot_kill console command (syntax identical to tf_bot_kick)
• Bots obey melee only mode a bit better
• Added func_nav_avoid to allow map creators control over where bots "like" to go

September 6, 2011 Patch

• Fixed a server crash related to bots

October 13, 2011 Patch (Manniversary Update & Sale)

• TFBots have a percentage chance of noticing weapon fire based on their difficulty level. Easy bots are fairly oblivious, and Expert bots notice pretty much everything.
• TFBots now treat certain weapon attacks as "quiet" (Spy knife, cloaking/uncloaking, some melee weapons, fists, etc). "Quiet" weapons can only be heard by TFBots when nearby, and their chance of being noticed is halved if the environment is "noisy" (ie., lots of non-quiet gunfire going on in the area). This greatly improves Spies ability to backstab TFBots without the entire team immediately turning on them.
• Spy bot improvements:
  • Spy bots are much better about circling around and backstabbing their victims now
  • Improved Spy bot target selection in some situations (ie: clusters of sentries and enemy players)
  • Spy bots will give up on an attack and retreat if an enemy sentry gun aims at them
  • Spy bots now avoid nearby enemies while disguised and/or cloaked so they don't bump into them and give themselves away
  • Spy bots now have a simple notion of when their “cover is blown" now
  • Spy bots lead their target's position as they chase them down for a backstab now
  • Spy bots don't go after victims until setup time has elapsed
  • Hard and Expert Spy bots avoid looking at their prey until they get close and go for the stab
  • Easy Spy bots don't avoid enemies, or try to get behind before stabbing
  • Normal Spy bots don't avoid enemies
  • Fixed bug where Spy bots would jump against the enemy spawn gates during setup time
• Medic bot improvements:
  • Medic bots stick much closer to running patients now
  • Medic bots stick much closer to their patient if they have an Ubercharge ready, or are deploying their Uber
  • Medic bots hide from Sentryguns now, too
• Pyro bot improvements:
  • Pyro bots are less "pushy" with their compression blast, but will use it against Ubers and to get enemies off of a capture point
• [Undocumented] Added new bot names.
