Dwarf — cut mutant, found in some versions. Ugly mutant, which was developed before the burer was cut before he did. Unlike the burer, was not restored in the third part, but found the build 1465. It is still unclear who is a subspecies of dwarf or burer? Anyway, dwarfs are far more common. They also resulted from experiments on the program "universal soldier". Because of the habitat in the dungeons of the skin is pale yellowish-white with a hint of green, go blind from the light. Good (but not like the burer) developed telekinesis and foresight, you're pretty good with your hands. Head they also hypertrophied. The degree of reasonableness is very high. Inhabited by dwarfs, like the burer in the underground and not sensitive to light. There they arrange workshops traps for stalkers with debris (rubble moves, causing the collapse of tunnels). See for yourself in the dark is wonderful. For some reason, I hate blind dogs. It is possible (not proven), have their own religious cult — worship stolen from stalkers things.
