Players will encounter familiar faces from the TV show, as some actors return to their iconic roles

Today during the Future Games Showcase, Owlcat Games — creators of Pathfinder: Wrath of the Righteous and Warhammer 40,000: Rogue Trader — announced that they have joined forces with Alcon Interactive Group to announce The Expanse: Osiris Reborn, a narrative third-person action RPG set in the universe of acclaimed TV series The Expanse, which is available on Blu-ray and streaming on Amazon Prime Video.

The Expanse: Osiris Reborn delivers an original story of survival and loyalty, and significantly expands the world of The Expanse depicted in the TV show and novels. Players step into the boots of a Pinkwater Security mercenary stranded in the wrong place at the worst time. Trapped on Eros Station during a deadly lockdown, they will need to lead a crew, take command of the system’s most advanced ship, and navigate a fractured solar system teetering on the edge of chaos.

“We’ve been dreaming about building a sci-fi action RPG of this scale for a long time, and The Expanse is the perfect universe to bring that vision to life,” says Owlcat’s Creative Director, Alexander Mishulin. “It’s a world grounded in realism and complexity, perfect for telling a story the way we like it — mature and character-driven, where your choices truly matter. We are excited to bring this new experience to our players and look forward to sharing more soon, especially knowing how many questions our fans will have.”

“The original Mass Effect trilogy was absolutely an inspiration to the team. It was iconic for the Xbox 360 generation of gamers. Many of us first played it in our teenage years, and it left a lasting impression,” says Yuliya Chernenko, Game Design Producer. “We are building on that legacy and expanding what players anticipate from this experience. Our story is deeply rooted in hard science fiction — one of the core reasons The Expanse universe resonates so well with its fans. The combat reflects the standards of modern action gameplay. The narrative emphasizes political tension and moral complexity. And yes — there’s romance too.”

Owlcat Games is proud to call The Expanse: Osiris Reborn its flagship project. Owlcat’s roster of titles is nothing short of jaw-dropping, with other major titles including Warhammer 40,000: Rogue Trader, Pathfinder: Wrath of the Righteous, and its newly announced title, Warhammer 40,000: Dark Heresy. Rest assured, the team behind The Expanse: Osiris Reborn is completely separate from Owlcat’s other projects and therefore will not hinder excellence elsewhere.

Key features of The Expanse: Osiris Reborn:

  • Create Your Own Captain: Play as an Earther, Martian, or Belter and take command of the system’s most advanced ship. Shape your journey through identity, leadership, and the pressure of survival.
  • Lead a Crew: Your companions are more than squadmates — they have pasts, motives, and a voice in your story. Your leadership decisions will determine how squadmate loyalty shifts under pressure.
  • Tactical Third-Person Combat: Implement real-time strategic cover mechanics using various abilities and squad coordination. Bring two companions into combat while others support from behind the scenes.
  • Explore a Divided Solar System: Travel across iconic locations from the TV show and books, like Ganymede, Ceres, Mars, and Luna. While traversing the various environments, players must uncover secrets and influence outcomes through their skills and decisions.
  • A Story-Driven RPG True to The Expanse: Immerse yourself in a narrative grounded in tension, consequence, and the complexity of humanity’s future among the stars
