Why it matters

Owlcat's first action RPG after a decade of isometric ones, and the first major game set in The Expanse.

About The Expanse: Osiris Reborn

Owlcat Games has spent a decade on isometric role-playing games, the Pathfinder titles and then Warhammer 40,000: Rogue Trader, and The Expanse: Osiris Reborn is its first third-person action RPG. It is also the first substantial game set in The Expanse, the hard science fiction universe of the novels and television series, where ships obey physics and the quarrel between Earth, Mars and the Belt does most of the damage. You are nobody important: a mercenary trying to keep a crew and a ship running, inside the choice-driven structure Owlcat is known for.

The target is spring 2027 on PlayStation 5, Xbox Series X|S and PC, with no exact day announced, and it is set to reach Game Pass on day one. A closed beta ran in April 2026 for people who had preordered. The risk and the interest are the same thing: Owlcat's strengths are reactive writing and systems depth, and neither has much to do with third-person shooting.
