Hi,
did you check out the icons in the forums area caled "Cyborg Factory" (startpage of the forum, scroll down)?
They show you exactly for which game a bot is designed
Most bots hosted here do support steam, only the retired bots might lack steam support. You should inevst some time in checking the different bot forums there, most have some sort of introduction the the bot in a stickiy thread on top.
There you will see for which mod/game a bot is designed and how to get it running.
(afaik podbot mm works okay,Joebot was fine last ime i need a clever bot (a year ago))
Cheers Onno
