Just wondering, but I saw a picture in one of the Bungie Weekly updates that showed a bunch of guys dressed as Noble 6 Spartans and then a guy that was in a hunched, discolored suit that seemed zombieish. So does this mean that in Infection you actually turn into a zombie instead of just your armor changing color? I know this is just speculation from a picture that wasn't even in game. Still, If it were so that would be magnificent =D EDIT: Found it\/
It's most likely just a custom spartan, with the zombie colouring, which will probably be the same sickly green, with (hopefully) splats of blood or something.
Maybe he'd have a different running animation that'd make him seem more zombie like. you know: arms spread out and kinda wobbly
But why should they give the Zombie a Bungie Shirt? I understand the VIP pass or whatever, but the shirt and the Jeans don't fit well into Halo in my opinion
