Reminds me of how a friend of mine in high school wanted to make a map of our school on CS. It wasn't particularly great, but the setup was definitely in favor of the terrorist team. The way our high school was setup, there was a bridge on the 2nd floor which you could see the entrances from. So, the terrorist team just needs to pick up some sniper rifles and it becomes really hard for the CTs to get in. The 1 exception was that I suppose one of the spawn points was supposed to be a student deciding to fight back or something, because one and only 1 CT spawn point was in a classroom. You died very easily if anyone decided to check. Anyway, he never did finish that map.
