Owlcat Games, developer of Pathfinder: Kingmaker, has announced The Expanse: Osiris Reborn, a new third-person action RPG coming soon to PC, Xbox Series X|S, and PC.

The Expanse: Osiris Reborn, a new action RPG set in the Expanse universe, has been announced by Owlcat Games. The game is set to launch soon for PC, Xbox Series X|S, and PS5, but it will not be available on last-generation consoles.
Shown off during the recent Future Games Show, the game will expand on the Amazon Prime TV series, with Owlcat promising fans a “mature and character-driven” story where choices matter.
What Is The Expanse: Osiris Reborn?
The Expanse: Osiris Reborn is a third-person action narrative-driven RPG set in a 24th-century solar system entangled in a conspiracy that threatens to destroy everything it touches. Players take on the role of a mercenary from Pinkwater Security and find themselves facing a personal crisis as their life unravels.
The announcement trailer reveals a game reminiscent of the Mass Effect series, featuring cover-based shooting and branching narrative paths that depend on player decisions. Owlcat’s previous work focuses on tabletop RPGs, such as the recent Warhammer 40:000 Rogue Trader, so The Expanse is a wild shift from their usual work.
Platform Details and Release Window
Owlcat has confirmed The Expanse: Osiris Reborn for PC, PS5, and Xbox Series X|S. Although a release date is not yet set, the game will not launch for PS4 or Xbox One, suggesting a fully immersive next-generation AAA title.
So far, the game is not available to pre-order on Xbox, PlayStation, or PC. Owlcat has set the release date as “coming soon.” Pre-orders are likely to open by the end of the year, with a possible release date in early 2026. This timeline is purely a guess based on the game’s announcement.
What Fans Can Expect
It’s clear from the trailer and what little we know that Owlcat wants to deliver a choice-driven RPG focusing on a high-stakes storyline and survival themes to drive the narrative forward.
The game will feature familiar characters, with Owlcat hinting that actors from Amazon’s show will reprise their roles in the RPG. The Expanse: Osiris Reborn offers fans the opportunity to explore an interactive world based on one of their favorite sci-fi universes.
Conclusion
Owlcat Games announces The Expanse: Osiris Reborn. The new action RPG is coming to PlayStation, Xbox, and PC soon. Are you looking forward to the game? Let us know in the comments.
