The Expanse: Osiris Reborn is a story-driven action–RPG set in the universe of the same name, with a focus on companions, player choices, and dynamic third-person combat. As a Pinkwater Security mercenary who survives a catastrophic incident on Eros, players must build a team to fight back against Protogen and their deadly experiments. While the game is set in the same universe as the books and show, it focuses on its own story and characters.

Closed Beta Content :
- In the closed beta, founders can choose to play as either a female character from the Belt or a male character from Earth, also choosing between specializing in officer or hacker abilities. Accompanied by their openhearted sibling J and supported by veteran mechanic Zafar, players will explore a remote space station belonging to their employer, Pinkwater Security, in the wake of escaping from the catastrophic events on Eros, famously known from the books and TV series.

Throughout the closed beta, players can interact with the station’s inhabitants, experiment with dialogue options and choices, and discover how everyday life on a space station full of mercenaries works. Once the masterminds behind the attack on Eros catch up to them, they’ll be thrown into the combat and experience the game’s upgrade mechanics firsthand.

In the final game, players will also be able to choose Mars as their main character’s background alongside the Belt and Earth, with more specializations and customization available than in the beta.

Closed Beta Availability :
- The beta is available now on Xbox Series X|S, Steam, and PlayStation 5 for founders who purchased The “Collector’s Edition” or “Miller’s Pack,” and will be running until the game’s launch in spring 2027. Founder’s packs can be purchased on the official website. Since the beta is a work in progress, performance may vary and won’t reflect the final quality of the game. On consoles, playing on Xbox Series X or PlayStation 5 is recommended for the best experience.

Owlcat aims to incorporate valuable player feedback collected from the beta into the final game.

How to Access the Beta on Your Chosen Platform :
- To access the closed beta, you need to be a Founder and own either “Miller’s Pack” or the “Collector’s Edition.” Then, please log in to your account on the official site, go to your profile, and head to the Digital Download tab. There, you will see an option to choose a platform for Beta access. Click on the “Choose the platform” button and select Steam, Xbox, or PlayStation 5. Then copy the code, activate it on the selected platform, download the Beta, and start playing!
