Burer — the result of genetic experiments conducted by the intelligence services of the criminals to develop telekinetic abilities. This low fat monsters with exaggerated facial features in the remains of clothing — worn form and black cloaks. They can move heavy objects through the power of thought, and create invisible force barriers. Once burer were ordinary people — probably prisoners or foolish volunteers, who are not lucky enough to get into the program to enhance the supernatural and, in particular, telekinetic, human capabilities. In the result of a side effect they turned into real monsters — lost human form and went astray. The burer is alien to human morality and compassion, they kill people for fun and food using a variety of tricks from his supernatural Arsenal — there are cases when these monsters lured stalkers into an ambush, posing as normal people. Spacious clothing, most likely the remnants of sperform that burer value much more than other mutants of the Zone, helps them pass for human (at least from afar). Most of these beings still live close to the abandoned laboratories, which led them to.
