Ghasts

Ghasts are commonly mistaken as Zombies due to their festering and rotten appearance, however, don't let their poor appearance make you underestimate them they are the most deadly of the undead, simply due to the fact They Will Never Die, everything has be tested on them, but they just keep getting back up, they’re determined too, they don't stop even when you run to a different state. The only way Hunter been able to avoid them tearing them apart and slowly eating them is by shooting them in the knees, they don't seem to be able to regenerate wounds as fast as normal humans, so that was all Hunter did for a long time with them, however, what Hunter didn’t realize is that Ghasts are able to take the skin, bones, or whatever, from humans and put it onto their own bodies and use it, good as new, that is until the added parts rot off.
