This is a minigame where zombies get in a warthog gauss and shoot blindly at zombies in a box. Humans have no shield and unlimited evade. There jump height is 150% and speed 110%. There is another way to play, though. Above the box are blocks and spartan lasers so that the zombies can shoot through. I've only played a couple games and it works fine and is fun to play. The only downside is that it uses just 5x5 so it is a little bland. If you want to help test or try it for yourself send a message to Elite Warrior5 on XBL.
Sounds a lot like that map that just recently got featured, which is pretty fun. The only thing though is that since the humans can move it will be extremely hard to actually hit them blindly with a guass shot, unless their area is very small. I'm up for testing, so if you need somebody invite me sometime.
The area is exactly 2x4 and humans don't usually win. It's about 1/5 times the human wins. EDIT: I meant 5x10.
