Owlcat Games has announced a major milestone in the development of the sci-fi RPG The Expanse: Osiris Reborn with the launch of its closed beta on April 22, 2026. The beta offers an exclusive preview of the third installment in the The Expanse series, which is being developed as a third-person action RPG. However, access is restricted to players who purchase either the Collector’s Edition or the Miller’s Pack, available exclusively through Owlcat’s official store. This approach marks a departure from traditional distribution models and emphasizes the developer’s focus on building a dedicated community of early supporters.
Set within the universe of the Pinkwater security firm—an original setting within the broader The Expanse universe—The Expanse: Osiris Reborn promises a fresh narrative experience that runs parallel to the television series. The beta will center on testing combat mechanics and zero-gravity movement, key features for the game’s space-faring environment. Players can expect enhanced squad combat and new character additions, which are designed to deepen the tactical gameplay. The beta will be available on Xbox Series X/S, PlayStation 5, and PC, ensuring broad platform accessibility.
The full release of The Expanse: Osiris Reborn is scheduled for Spring 2027 and will be available on multiple digital storefronts, including a day-one launch on Microsoft Game Pass Ultimate for both Xbox and PC. This strategic partnership with Xbox highlights the game’s accessibility focus and aims to reach a wider audience. Notably, the premium editions granting early beta access are not available on Steam, reflecting Owlcat’s deliberate choice to maintain control over distribution and foster direct engagement with its fanbase.
The announcement has generated significant excitement among fans of the franchise and the sci-fi RPG genre. The combination of deep narrative, tactical combat, and distinctive space-faring aesthetics promises a highly immersive experience. By integrating Game Pass and targeting an engaged community through exclusive editions, Owlcat Games is positioning itself as an innovator in the genre. The closed beta in April 2026 will therefore serve not only as a technical test but also as a crucial step in strengthening player engagement and preparing for the full release in 2027.
