Owlcat Opens Founders-Only Beta for The Expanse: Osiris Reborn

The limited test signals Owlcat’s pivot to a third-person, choice-driven RPG built for long-term feedback.

Overview

  • The closed beta, which opened Wednesday, is live on PlayStation 5, Xbox Series X|S, and PC via Steam.
  • Access is limited to founders who buy the Miller’s Pack or Collector’s Edition on the official site, with the test planned to stay open until the spring 2027 launch.
  • Founders activate access by logging into their account’s Digital Download page to choose a platform and redeem a code.
  • The build offers one early mission on Pinkwater station with exploration, full-voice dialogue choices, and two starting backgrounds that let you play as a Belter or an Earther.
  • Early hands-on reports praise impactful choices and replay value but flag frame-rate dips, rough cutscenes, sticky cover and movement, and combat that hits harder than Mass Effect with aggressive enemies and lethal grenades.
