The Ukrainian developer has now officially announced 'Call of Pripyat', though it's just a working title for now as S.T.A.L.K.E.R. gets its third stand-alone.
Unlike Clear Sky, Pripyat will be looking to events after the original Shadow of Chernobyl game. It'll have new story, more extended side-quests, and better UI for release this autumn.
S.T.A.L.K.E.R.: Call of Pripyat is exclusively for PC much like its predecessors and hopes to see a release sometime this Q3/4 if all goes to plan over at GSC Game World. It's new A-Life system should incorporate the best parts of the first two say the devs.
