The original Stalker was a bleakly impressive game set in the aftermath of the nuclear meltdown at Chernobyl.

This speedy follow-up covers similar ground and is peopled with the mutilated and the damned. Scavengers, scientists and military forces patrol the blasted areas of the game, each with their own agendas, which you have to explore as you complete your missions. There's enough that's different, though, to make this worth a play if only to see the depressing but remarkable world that's been created.
