Owlcat Games has revealed The Expanse: Osiris Reborn, an action RPG set in the universe of sci-fi TV series The Expanse.
The Expanse: Osiris Reborn, a collaboration between Owlcat and Alcon Interactive Group, is in development for PlayStation 5, Xbox Series X|S, and PC (where it’ll be on Steam, the Epic Games Store, and GOG). It debuted at this year’s Future Games Show with a trailer you can watch below. Scroll further for a synopsis, words from the creative leads, and some initial screens.
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.”
Key Features
- 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.

- 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.

This isn’t the first game based on The Expanse. In 2023, Telltale put out a five-episode adventure game (we covered each installment) centered around one of the characters on the show. But if you aren’t into the Telltale style, don’t fret; Owlcat is taking inspiration from Mass Effect with The Expanse: Osiris Reborn. Third-person combat, crew leadership, romance — all the hallmarks of Bioware’s legendary series are there.
The Expanse: Osiris Reborn is in development for PS5, XSX, and PC.
