The Expanse: Osiris Reborn now has a release window and a closed beta date, as Owlcat Games showcased a gameplay trailer at the Xbox Partner Preview.
The game is set for Spring 2027 and launches on PlayStation, PC, and Xbox Series X|S as a Play Anywhere title. It will also be available day one with Xbox Game Pass Ultimate. But before that, a closed beta starts on April 22, 2026.
The beta is not an open test, as access is tied to Founders’ support through the game’s official site, specifically by purchasing the Miller’s Pack or the Collector’s Edition. Once unlocked, the closed beta remains available all the way through release, so it’s not just a short beta weekend and more of a long-running pre-launch early access.
The beta content itself is a full mission pulled directly from the game. It begins after the player and their identical twin escape Eros by force on a seized ship and return to Pinkwater 4 station. That setup continues the game’s main premise, where you are a custom captain caught in the aftermath of mass violence on Eros, now flying an experimental enemy vessel and trying to survive in a solar system already on the brink of escalation.
The trailer showed some of the companions in action: Zafar, Regina, Teo, and Michael. All of them will have their specializations, strengths, and preferences, so the players will be able to tailor their strike teams for any mission.
Combat is leaning into a mix of cover shooting, destructible environments, gadgets, and squad coordination. The latest gameplay breakdown confirms assault rifles, shotguns, sniper rifles, pistols, SMGs, grenades, tactical scanners, zero-gravity tools, and deployable drones. The more distinct system is Exploits, which lets companions capitalize on environmental opportunities to wipe out groups of enemies when ordered at the right time.
Choice and consequence are still a core part of the game. Missions will have major decisions with long-term effects, and the beta itself contains one of those branching choices. The setting remains what made The Expanse such a phenomenon, with Earth, Mars, and the Belt locked in a future shaped by politics, class divisions, prejudice, and by space itself.
The Expanse: Osiris Reborn is Owlcat’s most ambitious project to date, and we spoke with the developers about it in our exclusive interview earlier this month.
