made by Vostok Games. same devs that made the s.t.a.l.k.e.r. games. Stalker series were a success because of the unique atmosphere that they have created. after a few failed stalker online attempts, for various reasons, they called it quits. so far its team vs team. later this year they are going to roll out open world, dayz style. graphics are good, gameplay is smooth. guns sound life-like. you level up and upgrade gear as u gain exp. been playing for a while , but lost interest because nobody has game. how that i got invites, started playing again, with the commies.
