Just some ideas:
For one, some abilities would be great! (StoneSkin, does # dmg back whenever you are hit by grab, etc) and some ways to choose your matches. Also, a AI battle and a in-match chat would be awsome!
These guys are awsome. They have bulletproof tires. They can't shoot at a huge truck in front of them. They can take a full clip of bullets to the head without dying.
Obviously, they're zombies.
