"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," said Owlcat's Creative Director, Alexander Mishulin.
"It's a world grounded in realism and complexity, perfect for telling a story how we like — 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."
Game Design Producer Yuliya Chernenko admitted the original Mass Effect trilogy "was absolutely an inspiration to the team."
"It was iconic for the Xbox 360 generation of gamers," Chernenko continued. "Many of us first played it in our teenage years, and it left a lasting impression. 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."
Like in Mass Effect, in The Expanse: Osiris Reborn you get to create your own captain (play as an Earther, Martian, or Belter and take command of the system's most advanced ship), lead a crew (your companions have "pasts, motives, and a voice in your story"), and experience tactical third-person combat, with real-time cover mechanics, various abilities, and squad coordination. And, just like in Mass Effect, you bring two companions into combat while others support from behind the scenes.
The Expanse fans will be pleased to know you get to visit familiar locations from the show and books, such as Ganymede, Ceres, Mars, and Luna. This is a story-driven RPG, with a narrative "grounded in tension, consequence, and the complexity of humanity's future among the stars." Yep, that sounds a lot like The Expanse, and, it turns out, Mass Effect.
Timeline wise, The Expanse: Osiris Reborn is set during the first two-and-a-half seasons of the show, or the first two books. The events of the game occur alongside the major events that transpire across the universe in The Expanse TV show / books during that time.
There's no release date just yet, but Owlcat said The Expanse: Osiris Reborn is "coming soon" to Steam, Epic Games Store, GOG, Xbox Series X and S, and PlayStation 5.
