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 RPG system is very open, allowing you to build whatever character you like. It's part of our vision of the game to allow you to experiment and find things you like."

Mishulin also mentions the game's combat experience, explaining that there will be no hard limitations on player freedom, like a class-based system. Osiris Reborn will supposedly encourage players to use different weapons they pick up in the environment and experiment with combinations of gunplay, drone-based support, and a ballistic shield. Each weapon you encounter will have different specifications, again encouraging players to experiment with new combinations and adapt their combat strategies based on those strengths and weaknesses.
The Expanse: Osiris Reborn doesn't have a launch date yet, but it is slated to launch on PC via Steam, Epic Games, and GOG, as well as on Xbox and PS5.
