The Expanse: Osiris Reborn – Beta in April, Full Release Spring 2027

Owlcat Games has officially revealed a spring 2027 release window for its highly anticipated sci‑fi action RPG, The Expanse: Osiris Reborn. Alongside this announcement, the developer confirmed a closed beta test set to launch on April 22, 2026, giving players an early opportunity to explore the next chapter in the Expanse universe. The game will release across PC, PlayStation 5, and Xbox Series X/S, with day-one availability on Xbox Game Pass Ultimate and Xbox Play Anywhere for console players.

While the exact release date is still to be confirmed, the spring timeframe offers fans a target for the game’s launch and reflects Owlcat's steady progress on development. The title builds on the rich Expanse setting with a mix of narrative-driven storytelling and intense third-person combat, drawing gameplay comparisons to titles like Mass Effect.

An imminent beta that will answer many questions

The upcoming closed beta will be accessible to players who purchase premium editions of the game, such as the Miller’s Pack or the Collector’s Edition. The beta will run on all launch platforms, including Steam for PC, PS5, and Xbox Series X/S. It will feature one of the earlier game missions and it's is expected to remain active until the game's full launch, allowing participants to experience missions, combat systems, and early story content.

Gameplay in The Expanse: Osiris Reborn emphasizes party-based tactics, with companion characters playing a central role in both narrative and combat. Each companion brings unique abilities and personality traits, ensuring that interactions with them are as meaningful as the high-stakes firefights players will encounter. This combination of narrative and combat has already drawn attention for its depth and strategic potential.

Set within the Expanse universe created by James S. A. Corey, The Expanse: Osiris Reborn casts players as a custom-built mercenary navigating political intrigue, galactic conspiracies, and survival challenges following a catastrophic assault on Eros Station. The storyline promises a blend of personal choices, sidequests, and high-stakes action that will appeal to longtime fans and newcomers alike.

For the franchise's dedicated followers, these announcements mark a significant step forward. The closed beta not only provides a chance to play the game early but also offers an opportunity for players to provide feedback that could influence the final release. However, some fans have expressed concerns about beta access being tied to higher-tier purchases, especially with the game launching on subscription platforms like Game Pass.

The Expanse: Osiris Reborn could become a major addition to both Owlcat’s portfolio after releasing titles like Warhammer 40K: Rogue Trader and Pathfinder: Wrath of the Righteous. The game takes a significantly different approach at gameplay promising expansive third-person action and compelling storylines.
