Days Gone is a survival horror game for the PlayStation 4 and PC (Windows). Set in a post-apocalyptic Oregon two years after the start of a global pandemic, former outlaw-turned-drifter Deacon St. John discovers the possibility of his wife Sarah still being alive, which leads Deacon on a quest to find her. Days Gone is played from a third-person perspective, in which the player can explore an open world environment. Players can use firearms, melee weapons and improvised weapons, and can use stealth to defend against hostile humans and cannibalistic creatures known as Freakers. A major game mechanic is Deacon’s motorcycle, which is used as the player character’s primary mode of transportation as well as mobile inventory.[1]https://en.wikipedia.org/wiki/Days_Gone
