PeZBOT is a multiplayer bot-mod for Call of Duty 4 and World at War. The aim of the mod is to introduce relatively life-like A.I. to local multiplayer games so those who choose not to go online or prefer to practice against bots before doing so, can. This mod is no longer in development but feel free to download the source code, create your own version and share it in the forums.
