Around the halfway point, the game becomes about collecting as many weapons, ammo, and artifact powerups as possible, then letting most of it rot in a chest.
Unfortunately for you, the Zone is filled with terrifying monsters, strange anomalies, surly treasure-hunters, and well-armed factions fighting for control of the Zone and its secrets. S.T.A.L.K.E.R.: Shadow of Chernobyl casts you as an amnesiac that must travel through the Zone - the area around the Chernobyl Nuclear Power Plant - to kill a person called Strelok.
