You should add a new way to verify when people are infected, like flashing a light in their eye and their pupil will seem red under the light. Also, you should add, as an undead after you ate like 4-3 survivors, you evolve into a runner, because at first you're a slow Sec Officer. Also, the admins should have the possibility [optional] to become very strong zombies, but slow ones. Meaning they will resist at many bashes against their head OR!!!! We could have Security gear zombies, Officers that got infected whilst wearing the riot gear/bulletproof armor.
