The franchise takes place in an alternate Chernobyl Exclusion Zone (or simply "the Zone"), where a number of classified laboratories were established following the nuclear disaster of 1986. Due to the experiments conducted in these laboratories, a second catastrophe occurred in 2006, which caused physical and meteorological phenomena all over the exclusion zone and mutation of local plant and animal life.[2] After the second disaster, the Zone grew rich with anomalies — inexplicable phenomena that don't obey the laws of physics or common sense (such as pillars of fire, lightning scatter, whirlwinds that tear everything that falls into them, etc).[3] The anomalies are causing artifacts to appear, which are items with unique and extraordinary properties such as anti-gravity or radioactivity absorption.[4] People who have come to explore the Zone in search of personal enrichment such as artifacts are known as "stalkers". Many of them are working on their own, though there are also several organized factions present. The Duty are a paramilitary organization that believes the Zone is a threat to humanity that must be destroyed. Conversely, members of the Freedom faction believe the Zone is a gift that should be freely accessible to all people. Bandits are wanted criminals and outlaws that have come to the Zone to hide from authorities, while the Clear Sky seek to understand the origins of the Zone. | Anything
