The Law of Pripyat

A creature in human form has come to Pripyat. It can control time and perfect biological machines for killing—fully subject to its will. Cruel, cynical, mercilessly and cold-bloodedly it destroyed its own brother.

And not only him…

Even Sniper’s friends are in mortal danger. Once he learns this, he rushes to help. Although he understands—there is simply no chance to win, the thing is too strong. But a true stalker will always prefer to die in battle with his friends rather than leave them in trouble.
