Discover the legendary S.T.A.L.K.E.R. universe!
Great Emission, the biggest anomalous energy blowout from the times of Second Incident at The Chernobyl Nuclear Power Plant, has shaken the world again and reshaped the Zone. To investigate its cause and and prevent future cataclysms is your only chance to survive in S.T.A.L.K.E.R.: Clear Sky.
With the anomalous activity at its maximum, the unstable Zone continues to tremor with outbursts. The transformation of the Zone map destabilizes the fragile balance of forces in the Zone. Hostilities for the new territories, artifact fields and spheres of influence flare up among groups. Feuds and friendships are left behind – now, everyone watches out only for themselves. The Faction War has begun. To survive, join one of the parties and knock out opponents over the Cordon... Or benefit from working for all the factions at once, like a true mercenary.
The safe and trusted pathways are no more. Known places disappear in impenetrable fields of anomalies, stalkers and entire expeditions vanish or remain trapped within. Mysterious territories that have been lost since the appearance of the Zone are opening up, calling for explorers. Your mission is to become a pioneer and explore all the new areas that have become accessible in "Clear Sky"!
As a mercenary named Scar, play a key role in Strelok’s fate and discover new details to the original game story, revealing its major secrets. Visit the familiar places as they were before the original game starts and witness the events that shaped the Zone to the years ahead. Game features:
