It's not the first time. 2007's Stalker: Shadow of Chernobyl was GSC's first attempt at crafting a disquieting, alien landscape in the Ukrainian countryside. A hybrid shooter borrowing a light quest format from RPGs, it was followed by Stalker: Clear Sky. But while the developers' first two bites of the radioactive cherry produced some impressively creepy moments, it's Call of Pripyat's Zone - set closer to the epicentre of the disaster - that stands as the ultimate realisation. By turns haunting, lonely, aggressive and sad, the Zone is the most evocative environment of any game, save BioShock's Rapture.
