S.T.A.L.K.E.R.: Call of Pripyat
With over 2 million copies sold, the new episode of the most internationally successful S.T.A.L.K.E.R. series seamlessly connects to the first part of the Shadow of Chernobyl. 
S.T.A.L.K.E.R.: Call of Pripyat takes PC gamers once again into the vicinity of the Chernobyl nuclear reactor that exploded in 1986. This so-called “Zone” is a highly contaminated area cordoned off by the military and now is combed through by the so-called stalkers, modern fortune hunters, in search of unique artifacts. In the role of Agent Alexander Degtyarev, who is dressed up as stalker, the player has to investigate the mysterious disappearance of five military helicopters and thereby stand one’s ground against the various stalker groups. 

S.T.A.L.K.E.R.: Clear Sky
S.T.A.L.K.E.R.: Clear Sky is set in 2011, one year prior to the events of the original S.T.A.L.K.E.R. game.
A group of stalkers, for the first time, reaches the very heart of the Zone-the Chernobyl Nuclear Power Plant-and triggers a cataclysm on the brink of a catastrophe. An immense blast of anomalous energy transforms the Zone: the once reliable and relatively safe roads are no longer so, the landscape is wiped clean by outbursts of anomalies, and previously unknown areas appear on the Zone map. Stalkers and expeditions perish or end up isolated within the lost territories.

S.T.A.L.K.E.R.: Shadow of Chernobyl
In 1986, the world’s worst nuclear disaster occurred at the Chernobyl power station. Soviet authorities established a 30km ‘Exclusion Zone’ around this nuclear wasteland, but in 2006 a second explosion rocked the stricken reactor, obliterating all living things and causing the Zone’s boundaries to ripple outwards. From this epicenter came waves of mutated creatures, deadly radiation, and a strange, anomalous energy. The Zone was cordoned off by the military, who would shoot on sight anyone foolish enough to brave the horrors within. 
It is now 2012 – man has ventured further and further into the heart of the Zone driven by reports of strange ‘artifacts’ imbued with anomalous energy. Mercenaries and bounty hunters compete to recover these artifacts, which command extortionate prices on the black market. Others seek to find the truth behind the Zone, while some merely revel in the desolate lawlessness of the place. Whatever their motivation, over time these individuals – Scavengers, Trespassers, Adventurers, Loners, Killer, Explorers and Robbers – have become known as S.T.A.L.K.E.R.s.
