the bot program is just in alpha phase, meaning its far from being completed. The Bots do better in some maps than they do in others. For example, on esf_afm the bots tend to stay on the ground and get stuck, on esf_cell_day the bots are ok. The biggest problem i have found is that when you make the game a team battle, the bots will try to kill there own teamates. I found that the free for all works best for the bots. But remember its in its begging phase of testing so be patient.
