Okay, so I laid out a little level on the space build map "gm_galactic". I placed all my little monsters, placed a few items and weapons here and there until there was some semblance of balance. I then looked over my work with pride. :) After I use up all my ammo except 50 bullets (is there a mod out there to completely strip you of weapons?), I gleefully get into starting postion and enable AI (This is going to be fun!).

I loose my first shot... and it was heard by every monster on the map. Oh my god the lag, the LAG. Every single enemy dedicated my processing power to finding out what the hell that noise was. I take it there are no rules for sound travel? As it stands, there is no way to make any kind of level. At least, not with the baddie density of doom.
