if you play the old version of esf aka esf 1.1 you need to download the bots from esf-world.com or that old Rick's site or [ME] - his old nick
otherwise you need to click SHIFT or '=' for the bots menues
the bots are included in esf 1.2 and on
though they create some bugs in esf which cause crashes for players that doesnt play with bots and doesnt need them nor the crashes they cause...
