I found this interesitng piece of mod that brings "bots" into the game......bots, that are very difficult to beat!
1) place the ukr_botAI.iwd file in your "/Call of Duty 2/main" directory.
2) run a tdm game
the mod is not compatible with some other mods.
Add this line to the end of ur "config_mp" file
scr_bots_number - number of bots, default 6
scr_bots_skill - skill of the bots THE LOWER THE NUMBER THE MORE SKILL, default 0.1
