The Expanse: Osiris Reborn is a sci-fi action RPG, based on the license of the TV series titled The Expanse, which in turn was an adaptation of popular novels written by a duo of writers under the pseudonym James S.A. Corey.

The game was developed by the RPG-specialized studio Owlcat Games (Pathfinder: Kingmaker, Pathfinder: Wrath of the Righteous, Warhammer 40,000: Rogue Trader), and its main source of inspiration was the Mass Effect series.
