The 13 Greatest Zombies in Video Games

So, it's zombie awareness month, apparently, so here are the greatest individual zombies of all time, but like in most things horror, there are rules. 

THE RULES: First things first - SPECIFIC CHARACTERS! I could toss out boomers, tanks, and lickers all day, but they're just "types" o zombie. In the grand scheme, nothing too special about them or unique. Second, these are characters that have to have come back from the dead. No Characters that "beat" death by way of necromancy (looking at you Dark Priest Shaft and Chakan The Forever Man). Third, they have to have bodies, so no ghosts and/or poltergeists.Finally, no vampires, as they fall into their own classification, and will one day get their own list.
