S.T.A.L.K.E.R.

S.T.A.L.K.E.R. is a first-person shooter computer game series by the Ukrainian developer GSC Game World. It currently consists of three games: S.T.A.L.K.E.R.: Shadow of Chernobyl (2007), S.T.A.L.K.E.R.: Clear Sky (2008) and S.T.A.L.K.E.R.: Call of Pripyat (2009).

It features an alternate reality theme, where a second nuclear disaster occurs at the Chernobyl Nuclear Power Plant in the near future and causes strange changes in the area around it. The game has a non-linear storyline and features gameplay elements such as trading and two-way communication with NPCs. The game includes elements of role-playing and business simulation games. In S.T.A.L.K.E.R, the player assumes the identity of an amnesiac "Stalker", an illegal explorer/artifact scavenger in "The Zone", named "The Marked One". "The Zone" is the location of an alternate reality version of the Zone of alienation surrounding the Chernobyl Power Plant after a second, fictitious explosion, which further contaminated the surrounding area with radiation and caused strange otherworldly changes in local fauna, flora and the laws of physics. "Stalker" in the context of the film refers to the older meaning of the word as a tracker and hunter of game or guide.

S.T.A.L.K.E.R. stands for "Scavenger, Trespasser, Adventurer, Loner, Killer, Explorer, Robber".
