Looming Ninja

Possible skin idea: zombies are cops and Humans are prisoners. So its kinda like jailbreak but has the ze elements. *(My original idea was humans was cops and zombies were prisoners for guns and shanks respectively) An idea from my Halo 3 days, FAT BOY: Mother zombies (probably 1 or 2 of them) has no knockback, BUT they're are slower (this is probably tough to balance). Any person they happen to infect has FAST movement speed but were easy to kill (faster than what we have now).
