Side Show looks really familiar. It's similar to one of the maps that was released on one of the MW3 Map Packs. The one with the gas station, and the overpass, and I guess like a house and a bathroom, there was also a hotel and a diner on the map.
So zombie understand how to use an exo-suit? I think it would be pretty interesting if there were a bunch of zombies flying around aimlessly and slamming into to walls and what not.
