S.T.A.L.K.E.R.: Call of Pripyat is the third entry in the acclaimed S.T.A.L.K.E.R. series. Using the real-life Chernobyl disaster as the game's backstory, Call of Pripyat takes players into a world where treasure hunters, mutants, bandits, and mercenaries roam the lanscape, often in bloody conflict with one another. The game offers single-player mode and multi-player mode, and combines the qualities of a first-person shooter (FPS) and a role-playing game (RPG).
