S.T.A.L.K.E.R. Clear Sky
The story of S.T.A.L.K.E.R: Clear Sky brings the players one year prior to the events of the original S.T.A.L.K.E.R. game in 2011.
A group of stalkers has for the first time reached the very heart of
the Zone - Chernobyl Nuclear Power Plant, and brings about a cataclysm
on the brink of a catastrophe. An immense blow-out of anomalous energy
changes the Zone. There are no more reliable and relatively safe roads.
The entire levels vanish in the outbursts of anomalies. Stalkers and
even expeditions die or end up sealed on the lost territories. New
areas, which remained unknown since the time of the Zone emergence,
appear on the Zone map. There are no more old enemies or friends - now everyone is for himself.
