In 1986, the world's most horrific nuclear disaster took place in Chernobyl. After subsequent unexplained explosions in 2006, a military exclusion zone is set up preventing access to the area. Stories of huge anomalous energy disturbances and sightings of strange creatures within the Zone are widespread. Players assume the role of a S.T.A.L.K.E.R., a mercenary paid by scientists and other undisclosed groups, who is trying to regain his memory. Players will experience a unique "Survival-Shooter" game that combines action, stealth, survival and Role-Playing Game (RPG) elements to create an incomparable experience in the Zone.
