well he probably thought 800 was a good value...
I think so too..
I've played de_dust for about an hour and saw after about 5 or so bots die in one area the rest of the living bots start running the other way

this is what happen..
there are 30 bots..
15 T, the whole team, goes through underpass.
5 of them get killed and the other 10 start running back up the stairs and going to hall..

at least it works pretty well...
