From The TimeSplitters Wiki

Al Bots are computer controlled characters in the TimeSplitters series. You can have up to ten in one game. You can control which character they are, the amount of their stars, which team they're on, and whether or not they're playing. Al Bots do have limitations, whoever. They cannot get into gun emplacments, and they can not get into vehicles either. They also cannot activate levers. For example, they cannot cause the subways to come in the Subway area.
