The Expanse: Osiris Reborn Will Trade Epic Space Battles for In-Depth Combat and RPG Mechanics
The Expanse: Osiris Reborn is an upcoming squad-based RPG from Owlcat Games that promises to adapt the popular sci-fi story of The Expanse. The story-driven, party-based RPG will, however, skip out on The Expanse's iconic space battles. Instead, The Expanse: Osiris Reborn will focus more on interpersonal relationships and the effects of the story on the Belters and the inhabitants of the inner planets. Players will base their operations out of a ship, and the studio is leaning into the property's hard sci-fi origins, using physics and environmental cues to make space feel like "a very dangerous and unwelcoming place to be," but they won't be able to use that same ship to wage war in the vastness of space.
In a recent interview with CNET, the game's creative director, Alexander Mishulin, explains that, while Osiris Reborn won't revisit the story of Holden and the crew from The Expanse, the game will explore the repercussions of the events of season one and two of the TV series. Players will, however, run into characters from the Rocinante crew in their adventures, and they will seemingly experience the horrors of the Protomolecule first-hand. The game will allegedly take inspiration from a number of games, including Mass Effect, Dark Souls, and Baldur's Gate 3. Specifically, the game studio says that Osiris Reborn will offer a lot of flexibility when it comes to the type of character you want to build and how you want to develop them throughout the story. Additionally, NPCs and companions will each have their own personality and develop on their own time, even if they're not part of the player's party.

The Expanse: Osiris Reborn - Q&A
Couchpotato spotted an Q&A for The Expanse: Osiris Reborn on Wccftech:
The Expanse: Osiris Reborn Q&A – ‘It’s a Very Good Match for Us Because of the Stories We Want to Tell’
The announcement of The Expanse: Osiris Reborn was undoubtedly one of my personal highlights of this year's Summer Game Fest season.
The Expanse is one of my favorite sci-fi settings, and I've devoured all the books and the seasons of the great TV series adaptation on Prime Video. A couple of years ago, Telltale released a game based on the show, but its genre and its scope weren't exactly thrilling.
When did you decide to make this game, and how did you contact the license holder?Alexander Mishulin: With all our projects, it's quite a similar story because, internally, we had a group of friends who came out with an internal pitch for the game. We discussed it. We loved it. We talked a lot about how we could make this game, how it could be different and interesting.
The Expanse IP is a very good match for us because of the stories we would like to tell. It's grounded, with many choices and consequences, and all about people and companions. The Expense is all about how humanity, while being more advanced in 300 years from now, is still very much human with all its genius traits, flaws and everything. When we had an internal pitch that we loved and we understood that we could make it happen, we started working out the business side of the details. We approached Alcon with our idea and they were as excited as we were, so the project began and we started to work on pre-production.
Okay. Is the game still in pre-production, or have you moved to production?
Alexander Mishulin: The development started in 2021. We spent almost a year doing prototypes, transitioning between the genres because the game we are making is not quite similar to the games we have done previously. So we established new processes, established new approaches, and made sure that everything is working well, the shooting parts are working well, and of course, established all the new processes to make content. After that, we started making our vertical slices, and now we are full in production.
