The Expanse: Osiris Reborn is a new narrative-driven sci-fi RPG inspired by Mass Effect Pulasthi Ariyasinghe Neowin @LoneWolfSL · Jun 7, 2025 17:18 EDT Out of nowhere, a narrative-driven sci-fi action RPG has been announced that will take players into the universe of The Expanse TV show and novels. The reveal trailer landed today during the Future Games Showcase, offering both a cinematic look at the setting as well as snippets of gameplay. Check out the The Expanse: Osiris Reborn debut trailer above. The studio behind the project is Owlcat Games. Some may remember that name from being involved in the role-playing titles Pathfinder: Kingmaker, Pathfinder: Wrath of the Righteous, as well as the most recent hugely well-received RPG Warhammer 40,000: Rogue Trader. Now, the studio's sights are set on The Expanse universe, and it's going for the over-the-shoulder third-person gameplay route for the first time. “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." The story will have players taking the role of a custom captain that can be from the Earth, Mars, or the Belt to take control of the most advanced ship currently available. There's a crew to meet and lead, tactical third-person combat, and, as expected from this franchise, a divided solar system to navigate and make decisions on. The studio was also very direct about this experience being inspired by BioWare's Mass Effect trilogy. Aside from the action-heavy gameplay seen in the trailer, Owlcat is promising plenty of political intrigue, as well as romance options for players to dive into. Game Design Producer Yuliya Chernenko added "many of us first played it in our teenage years, and it left a lasting impression," and that "we are building on that legacy and expanding what players anticipate from this experience." The Expanse: Osiris Reborn does not have a release window just yet, but it will be coming out on PC (Steam, Epic Games Store, GOG), Xbox Series X|S, and PlayStation 5.
