Condition Zero comes with custom bots and you can control or change their difficulty level before creating a server.
I wouldn't recomend using more than 1 kind of bots on CZ at a time.
If you want CS Bots I can point you to Count Floyds 2.6 Pod Bots
and [-E-]POD Bots I tried them and they did fantasitc work but you will need to turn down the level of skill they use before trying them, because its really high
