The plot of S.T.A.L.K.E.R .: Clear Sky takes players a year before the events of the original S.T.A.L.K.E.R. in 2011.
A group of stalkers for the first time got to the very heart of the Zone - the Chernobyl nuclear power plant, provoking a cataclysm that almost led to a catastrophe. A massive burst of anomalous energy changes the Zone. There are no more proven and relatively safe roads. Whole levels are lost in flashes of anomalies. Stalkers and even expeditions die or find themselves locked up in the lost territories. New territories, about which nothing has been known since the appearance of the Zone, appear on the Zone map. Emissions continue to shake the area. The zone is unstable. Abnormal activity is at its maximum.
Changes to the Zone map known to stalkers upset the fragile balance of power in the Zone. Between the factions, enmity flares up for new territories, fields of artifacts and spheres of influence. There are no more old enemies or friends - now it´s every man for himself. The Faction War broke out between the factions.
The main character is a mercenary who, by the will of fate, found himself at the very edge of the confrontation between the stalker factions, the Shooter and even the Zone itself. The main character will play a major role in the events that led the history of the Zone to the point from which the original S.T.A.L.K.E.R. game begins.
What awaits stalkers in the newly opened depths of the Zone? What new dangers are lurking in the new territories? Why are emissions shaking the Zone? Why has the Zone changed? How to eliminate its instability? Which faction will prevail in the confrontation between the factions? Why did the Shooter get into the death truck? What happened to the Shooter before that? Was there any other choice? You will find answers to these and many other questions in the official prequel "S.T.A.L.K.E.R .: Clear Sky".
