Given the team-based competitive nature behind many first-person shooters, a player who plays offline games, presumably with limited or no internet access, will be missing out on a huge portion of the game.

Another distinct definition of bot is that of a computer program which is commonly designed to perform monotonous or hard-to-achieve tasks such as "farming" and raising levels in RPG-type games. As a result, most RPG games have banned them from use because it is considered '''''cheating'''''. In FPS games this type of bot is also known to be a form of cheating. It helps players achieve better scores by improving their aim and reflexes which, in the extreme case, are completely controlled by the bot software.

A bot (short for robot) is similar to an NPC in a multiplayer game, usually designed to behave like a human-controlled player. An example is the Counter-Strike: Source Counter-Strike: Source bot.

Warning.pngRisk of Confusion:Bots are considered players, not NPCs.

Long Version

Given the team-based competitive nature behind many first-person shooters, a player who plays offline games, presumably with limited or no internet access, will be missing out on a huge portion of the game. To remedy this, these games usually come with bots, which are NPCs that behave like a human player.

Another distinct definition of "bot" is that of a computer program which is commonly designed to perform monotonous or hard-to-achieve tasks such as "farming" and raising levels in RPG-type games. As a result, most RPG games have banned them from use because it is considered cheating. In FPS games this type of bot is also known to be a form of cheating. It helps players achieve better scores by improving their aim and reflexes which, in the extreme case, are completely controlled by the bot software.

Bot Classes and Properties

Bot Class Game Target Class
for I/O, VScript 		Affected by...?
NPC Clip LOS Blockers
cs_bot Counter-Strike: Source Counter-Strike: Source player Yes No
Counter-Strike: Global Offensive Counter-Strike: Global Offensive cs_bot1 Yes Yes
Counter-Strike 2 Counter-Strike 2 cs_bot[confirm] Yes[confirm] Yes[confirm]
survivor_bot Left 4 Dead Left 4 Dead
Left 4 Dead 2 Left 4 Dead 2 		player No Yes
tf_bot Team Fortress 2 Team Fortress 2 player No No
1: In VScript, if bot is the handle of a cs_bot, then bot.GetClassname() always delivers "player".
If a cs_bot receives a targetname, it turns into a player.

Determining game mode

In Counter-Strike: Source, the built-in bots determine what game mode the current map is designed for based upon the last instance of an entity with one of the following classnames:

Classname Game mode
func_bomb_target Bomb defusal
Obsoleteinfo_bomb_target Bomb defusal
func_hostage_rescue Hostage rescue
Obsoleteinfo_hostage_rescue Hostage rescue
hostage_entity Hostage rescue
Obsoletefunc_vip_safetyzone ObsoleteVIP assassination

If none of these are currently present, then it defaults to "fight yard" (eliminate opposing team).

Icon-Important.pngImportant:This means that if a map has both hostages and bombsites, bots will only go for one or the other! A third-party bot plugin is necessary for such maps to work correctly with bots.

Related Console Commands and Variables

All games with bots have ConCommands and ConVars to control them. These might have slightly different side effects per game.

Note.pngNote:Team Fortress 2 The following need the prefix tf_, such as tf_bot_add.
Note.pngNote:For commands to modify where bots can go, see Nav Mesh Commands. To learn how to use them, see Nav Mesh Editing.
ConCommand / ConVar Description
bot_add Adds a bot to the server. Parameters can be used to set the name, team or difficulty of the new bot. This command might do nothing the first time if bot_quota_mode is set to fill.
bot_dont_shoot Counter-Strike: SourceCounter-Strike: Global Offensive Determines whether bots will intentionally shoot at enemies or not. They might still shoot for example if they are blinded by a flashbang or if a func_breakable is in their way.
Note.pngNote:In Left 4 Dead Left 4 Dead and Left 4 Dead 2 Left 4 Dead 2, even if this parameter is off, bots will frequently shove (+attack2) func_breakable objects nearby them anyway, or entities perceived to be in their way.
bot_kick Remove all bots from the server. Parameters can be used to target only specific bots.
Counter-Strike: Global Offensive Bots don't die in this process such that they don't drop any equipment.
bot_kill Cheat command that makes all bots suicide. If a parameter is given, tries to kill the bot with that name.
bot_quota
bot_quota_mode		 Determines the number of bots on the server that are added automatically.
bot_stop If set to non-zero, bots won't do anything.
bot_moveto Will move a generic bot.
Icon-Bug.pngBug:If used on a NextBot, the game will crash. (in Team Fortress 2)
