The closed beta test for third-person action RPG The Expanse: Osiris Reborn is now available for PlayStation 5, Xbox Series, and PC via Steam, developer Owlcat Games announced. A full launch will follow for PlayStation 5, Xbox Series, and PC via Steam, Epic Games Store, and GOG in spring 2027.
Although called a “closed beta,” today’s release of The Expanse: Osiris Reborn is more akin to an Early Access release, as the test is only available to users who purchase the “Collector’s Edition” or “Miller’s Pack” via the game’s official website, and will run until the game’s official release.
Here are the details:
About
The Expanse: Osiris Reborn is a story-driven action–RPG set in the universe of the same name, with a focus on companions, player choices, and dynamic third-person combat. As a Pinkwater Security mercenary who survives a catastrophic incident on Eros, players must build a team to fight back against Protogen and their deadly experiments. While the game is set in the same universe as the books and show, it focuses on its own story and characters.
Closed Beta Content
In the closed beta, founders can choose to play as either a female character from the Belt or a male character from Earth, also choosing between specializing in officer or hacker abilities. Accompanied by their openhearted sibling J and supported by veteran mechanic Zafar, players will explore a remote space station belonging to their employer, Pinkwater Security, in the wake of escaping from the catastrophic events on Eros, famously known from the books and TV series.
Throughout the closed beta, players can interact with the station’s inhabitants, experiment with dialogue options and choices, and discover how everyday life on a space station full of mercenaries works. Once the masterminds behind the attack on Eros catch up to them, they’ll be thrown into the combat and experience the game’s upgrade mechanics firsthand.
In the final game, players will also be able to choose Mars as their main character’s background alongside the Belt and Earth, with more specializations and customization available than in the beta.
Closed Beta Availability
The beta is available now on Xbox Series X|S, Steam, and PlayStation 5 for founders who purchased The “Collector’s Edition” or “Miller’s Pack,” and will be running 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 for the best experience.
Owlcat aims to incorporate valuable player feedback collected from the beta into the final game.
