This looks nice, maybe you can have an EDF where you can place bot spawnpoints and in their properties, you can set their skin, team ( Which will have the default team colour ), name and so on.
Justnow, I think you have to script bots into maps and since I don't have a clue on much scripting, it might be a bit hard for me to script bots into a load of maps.
Anyways, it looks good so far, keep up the good work.
