So I gave in and went and got Origins. I'm 3 Zombies away from round 2.
I kill them and I noticed 2 Zombies looking like a Bath Salt victim spazin' out. They were kind jerking around on the ground.
Is this a known bug, glitch, or what?
I don't know what happened, but I had the same thing on Moon. I kill a zombie and its foot or hand starts rolling. Anyways, I'm on Xbox so I wouldn't know.
