The Expanse: Osiris Reborn Sets Spring 2027 Launch With Founder Beta Starting April 22

The yearlong trial run points to a feedback-first push as Owlcat shifts into a Mass Effect–style third‑person action RPG.

Overview

  • A new gameplay trailer Thursday confirmed a Spring 2027 release, day-one Xbox Game Pass support, and a founders-only closed beta that begins April 22.
  • Access to the beta requires buying the Miller’s Pack or the Collector’s Edition on Owlcat’s site, and the studio says the test will stay open until launch.
  • The beta includes a full early mission on the Pinkwater 4 station that lets players meet Zafar, try dialogue choices, and test cover shooting, gadgets, and zero‑g traversal.
  • Final platforms at launch are PS5, Xbox Series X|S, and PC on Steam, Epic, and GOG, though coverage differs on beta platforms, with Xbox Wire calling out Xbox access and other outlets listing PC and PS5 as well.
  • Owlcat says it uses generative AI only for prototyping and placeholders during development and that all writing, voices, and in‑game assets in the final release will be human made.
