Unlike the S.T.A.L.K.E.R.: Clear Sky stand-alone expansion, whose temporal location made it a prequel, STALKER: Call of Prypiat picks up the story from where we left it at the end of the first episode. Three years after the release of STALKER: Shadow of Chernobyl, the developers of GSC Game World invite us to return to the zone, proposing the first true official sequel of the lucky brand.
