The Encased story is set before, during, and after an apocalypse in an alternative vision of the 1970s after humanity discovers The Dome, a giant zone left by an unknown civilization colloquially known as The Forefathers.
Players begin their journey with one of five disciplines - science, engineering, security, management, or convict - which affects both their initial stats, specialization, and opens (or prevents) unique dialogue within the game.
However, the starting mission turns into a disaster as a strange anomaly of incredible proportions – The Maelstrom – goes out of control, cutting all communication with the outside world and plunging The Dome into chaos.
