About Osiris Reborn Guides

Osiris Reborn Guides is an independent guide site for The Expanse: Osiris Reborn, the third-person action RPG from Owlcat Games. It is written for players who want the confirmed facts without wading through speculation.

What we cover

Release timing and platforms, Game Pass and closed-beta access, the classless skill system, and the crew. Each guide is scoped to one question and answers it in the first paragraph.

How claims are labelled

Confirmed means the detail comes from Owlcat's own store page, press release or Steam announcement. Reported means it comes from a preview or second-hand outlet that we could not trace back to an official post. Anything Owlcat has not announced is written as not announced — we do not fill gaps with guesses.
