German publisher bitComposer has pushed the release of S.T.A.L.K.E.R. sequel Call of Pripyat to Q1 2010. Call of Pripyat had been pencilled for an autumn launch.
Call of Pripyat continues where the original S.T.A.L.K.E.R. campaign left off, sending you, a Ukranian special agent, into the Chernobyl disaster area to investigate why a government mission to secure the zone has failed and no troops have returned.
Mechanically, A-life has been improved, and developer GSC has handmade 70 new quests in an effort to abolish the random nature of the first game.
Our Call of Pripyat page below has more.
