The Expanse: Osiris Reborn release date, platforms, and gameplay details

The Expanse: Osiris Reborn, Owlcat Games' upcoming third-person action RPG, is set to launch in spring 2027 on PC, PlayStation 5, and Xbox Series X|S. Announced with a fresh gameplay trailer, the game plunges players into a gritty sci-fi universe where survival depends on tough choices and tactical combat.

Set in the 24th century within The Expanse universe, players take on the role of a Pinkwater Security mercenary caught in a deadly lockdown on the asteroid Eros. What begins as a routine shore leave turns into an expansive solar system conspiracy, forcing players to command a top-tier ship and make decisions that ripple across a fragile political landscape.

Players can customize their captain’s origin-Earther, Martian, or Belter-impacting how they navigate alliances and confront threats from an enemy determined to eliminate them. The narrative highlights relationships with a diverse crew, each with their own histories, shaping the story based on player choices. Trust and loyalty become vital resources while the ship serves as both a strategic command center and home base.

Combat is tactical and real-time, featuring cover-based gunplay and special abilities. Two of your crew join the frontline, with others providing distant support, like system disruption or enemy distraction. This dynamic combat system encourages strategic thinking and adaptability in response to ever-escalating dangers throughout the solar system.

The game invites players to explore iconic locations such as Ganymede, Ceres, Mars, and Luna, each with unique environmental challenges and political intrigue. These familiar settings from the series offer rich storytelling opportunities and encounters with characters who highlight the interconnectedness of this sprawling universe.
