Playing this great game since day it was released and never ever had something like this happened. I'm on the main floor (down the stairs; floor with the roaches and Red) and I encounter a Master Mutant who WON'T die! All he does is go unconscious for a few seconds then he gets up and his hit points are reset. I've even tried using the cheat code "kill" and the same thing happens. If any of you know what can be done I'd sure appreciate it.
