GSC Game World's made no secret about the need to be prepared for new S.T.A.L.K.E.R. announcements, but news that a full new irradiated shooty adventure in the pipeline is set to release in the first half of 2008 will likely raise an eyebrow or two. It's called S.T.A.L.K.E.R.: Clear Sky.
Revealed in the latest edition of PC Zone magazine, Clear Sky is a prequel to Shadow of Chernobyl. Without giving away too many plot for fear of spouting spoilers, it fleshes out the origins of one of the main characters in the first game who, stepping into the boots of a stalker from a rival faction this time around, you're out to kill.
