The game takes place in the year 2015, ten years after a deadly man-made virus (Spontaneous Genome Degeneration Syndrome) kills billions across the planet. The initial protagonists are four soldiers who have spent the last decade in a bunker at a Russian Kalinina military base where they were stationed. What greets the survivors initially is a barren world populated by sporadic groups of survivors. Every community is self-sustaining, with trade organized by the Seeker Guild. Seekers are people who scavenge pre-catastrophe (referred to as Old Time) equipment from ruined cities, "from sour drops to tanks". It is also revealed that after the disaster, central society became non-existent, with territories being controlled by gangs; apparently the area where the group's base was located was the territory of the Slingers, a group of thugs and thieves who have started to capture and kidnap people lately.
