Viva Media and bitComposer Games announce that S.T.A.L.K.E.R.: Call of Pripyat is now available in North America, offering the third installment in GDC Game World's first-person shooter series set in the vicinity of the Chernobyl nuclear power plan accident. Word is: "Where most first person shooters rely on relentless action to engage their players, Call of Pripyat goes in an entirely different direction, allowing for long moments of silence amidst a desolate landscape and an ever changing vista. The environment is dynamic: day and night alternate and are filled with thunderstorms and sunshine, and the game's artificial intelligence interacts with itself beyond the peripheral of the player. The game truly takes on a life of its own."
