S.T.A.L.K.E.R.: Call of Pripyat

The events of S.T.A.L.K.E.R.: Call of Pripyat unfold shortly after the end of S.T.A.L.K.E.R.: Shadow of Chernobyl. Having discovered about the open path to the Zone center, the government decides to hold a large-scale military "Fairway" operation aimed to take the CNPP under control. According to the operation's plan, the first military group is to conduct an air scouting of the territory to map out the detailed layouts of anomalous fields location. Thereafter, making use of the maps, the main military forces are to be dispatched. Despite thorough preparations, the operation fails. Most of the avant-garde helicopters crash. In order to collect information on reasons behind the operation failure, Ukraine's Security Service sends their agent into the Zone center. From now on, everything depends on you.

In the aftermath of a mission to disable a device deep within the Chernobyl exclusion zone, stalkers gain access to areas closer to the reactor than ever before. Seizing the opportunity, the Ukrainian government launches Operation Fairway, a reconnaissance flight over the Chernobyl Nuclear Power Plant, but all five of its helicopters go down under mysterious circumstances. Major Alexander Degtyarev, a seasoned stalker and agent of the state security service, is dispatched into the Zone to locate the wreckage and uncover what brought the aircraft down.
