Bots are AI controlled entities that resemble the player. They generated when a new round starts. There are generally over 20 to 30 bots each game. Their purpose is to help players get more kills. As the game progresses, the bots become more powerful, as they acquire weapons and start firing at you, rather than simply running away. Many players dislike them due to the sheer number, since most lobby's have a lot of bots now.
