Owlcat Games has announced a release window for The Expanse: Osiris Reborn, their new third-person action RPG based on the TV series of the game name.

The Expanse: Osiris Reborn is now launching sometime in spring 2027 across Windows PC (via Steam, GOG, and the Epic Games Store), Xbox Series X|S, and PS5.

The game will also be on Game Pass, and a closed beta test will run from April 22nd until the game’s launch – if you buy the Collector’s Edition or buying the game’s Miller’s Pack.

Here’s a rundown on the previously announced game, plus a new slice of gameplay:

The Expanse: Osiris Reborn is a story-driven action RPG set in The Expanse universe with focus on companions, player choices, and dynamic third-person combat. As a Pinkwater Security mercenary who survives a catastrophic incident on Eros, players have to build a team to fight back against Protogen and their experiments. Though the game is set in the same universe as the books and show, it focuses on its own story and characters.

The beta will allow players to explore a remote space station belonging to their employer Pinkwater Security in the wake of escaping from the catastrophic events on Eros known from the books and TV series. Along with exploring this new environment, they will be able to interact with its inhabitants and experiment with dialogue options and choices. Once the masterminds behind the attack on Eros catch up to them, they will also experience the combat and upgrade mechanics first hand.

Owlcat aims at incorporation valuable player feedback from the beta into the final game. 

The beta launches on April 22nd on Steam, Xbox Series X|S, and PlayStation 5. It will be available for founders who purchased The Collector’s Edition or Miller’s Pack, and will run until the game’s launch in Spring 2027. Founder’s Packs can be purchased on the official website. Since the beta is a work in progress, performance may vary and won’t reflect the final quality of the game. On consoles, playing on Xbox Series X or PlayStation 5 is recommended.
