I would like to apply (program) the Artificial intelligence methods to create a intelligent game bots for a first person shooter game. Do you have any knowledge from where can I start to develop as a Linux user? Do you have a suggestion for an easy-to-start game for which I can develop bots easily, caring more about the result of my algorithms rather than spending a lot of time dealing with the game code? I've read some publications about the applied methods to Quake 3 (c) and Open Arena. But I couldn't find the source codes and manuals describing how to start coding( for compiling, developing ai and etc.).

I appreciate your help.
