Osiris Reborn Release Date, Platforms & Game Pass

Updated September 23, 2026 · Facts cross-checked against the sources listed below

The Expanse: Osiris Reborn releases in spring 2027; Steam lists it as Q2 2027. There is no exact date yet. It is coming to PC (Steam, Epic, GOG), PlayStation 5 and Xbox Series X|S, and it will be on Xbox Game Pass Ultimate from day one. It is not out yet, but a paid Beta has been playable since April 22, 2026. There has been no delay: the window has not moved since Owlcat first gave it in March 2026.

Release window: spring 2027

Owlcat gave the window on March 26, 2026, at the Xbox Partner Preview, alongside the gameplay trailer and the Beta date: the game “will be released in spring 2027”. Steam shows “Q2 2027”. There is no exact day. The PlayStation Store holds a year-only placeholder, GOG says “coming soon”, and Owlcat’s own store says “to be announced”.

Game8 describes the window as “Spring (Q1) 2027”. Owlcat has never said Q1, and Steam says Q2, so we go with Q2.

The PlayStation Store listing flags PS5 Pro enhancements ⚠ pre-release store data. Xbox Wire also mentions Xbox Cloud Gaming. PC specs are on the system requirements page.

Game Pass and Play Anywhere

Xbox Wire, written by Owlcat’s community manager, says the game will be “available day one with Xbox Game Pass Ultimate”. It supports Xbox Play Anywhere, so one purchase covers Xbox Series X|S and the Microsoft Store PC version.

No delay so far

We read all ten official news posts and all sixteen Steam news items. None mentions a delay, and the window has read spring 2027 or Q2 2027 since it was first given. We will update this page the day that changes.
