Just saw this game for sale in a GAME shop (UK) today. Looks interesting but I'd definitely like to find out more
about it before I buy it.
It sounds rather like a mixture of Far Cry and Stalker:Oblivion Lost (or whatever it's called now). The plot and setting seems rather Far Cry-ish but the huge, open landscapes and drivable vehicles sound like Stalker.

For anyone that's played it, or knows more about it, what's it like?
