Dark stalkers are a group of semi-mutant stalkers. There is no exact information about them. Almost always, dark stalkers have a disfigured head, and the rest of the body is often not even touched. Some attribute this to laboratory experiments or exposure to special radiation. They are very aggressive, they attack everyone except the Monoliths. Mutants do not touch them, unless, of course, dark stalkers start attacking mutants themselves. Often used by the Monoliths as cannon fodder, along with common mutants. Dark stalkers live in the center of the Zone, around the Chernobyl nuclear power plant. The purpose of the mutated stalkers is to help some "parents" who control the Zone, only they promise the half-mutant stalkers to remake the world for them, to provide them with rights and everything they need, and all this still needs to be earned.
