The announcement of a new Stalker game, Call Of Pripyat, offers an intriguing prospect. It's a trilogy-completing work - with Clear Sky acting as prequel - and it proports to show what took place in the zone after the events of Shadow Of Chernobyl. The initial announcement seemed to promise a great deal: enhanced A-Life, more freedom, and more survival conditions to consider. But what else is in there? And what did the Ukrainian company learn from Clear Sky? GSC's Oleg Yavorsky took some time out to answer RPS' questions, and to reveal a bit more about Call Of Pripyat.
