I'm actually work on a map similiar to this, but gameplay is actually included. I'm just now entering the testing phase. http://www.forgehub.com/forum/testers-guild/72693-bed-bugs-thursday-may-28-2009-6-00-pm-est.html
Sorry dude, to me it sounds kind of boring... I'd probably have more fun with speed and gravity to the extreme, invincibility on, everyone in mongooses and one guy chasing them with unlimited nades and grav hammer : ) No but you should really make something like that I love those games, lol.
