The game is loosely based on Secret Wars (2015 Event) and is set in the Battleworld, a patchwork world made up of fragments of different realities abducted by God-King Maestro. Each land belongs to a separate House ruled by a Baron which are in a state of uneasy alliances between one another. Many years after the Battleworld's formation, the uneasy peace is disturbed by the sudden death of the God-King Maestro leading to the Houses vying for control over its resources.
