Frequently Asked Questions
Is Osiris Reborn out yet?
Not yet. The Steam store page lists Q2 2027 and Owlcat's press release says Spring 2027; the overlap is April to June 2027. No exact release day has been announced.
Which platforms is it coming to?
PC via Steam, Epic Games Store and GOG, plus Xbox Series X|S and PlayStation 5. It launches on Xbox Game Pass day one. No Switch version and no PS4 or Xbox One version has been announced.
Does Osiris Reborn have classes?
No. You pick a starting specialization, then invest in four combat skill trees — Marksmanship, Gadgets, Survivalist and Leader — plus two exploration trees. Owlcat says your weapons and gadgets, not the trees alone, define how you fight.
Is the seven-companion roster official?
No. Owlcat has not published a companion roster. The seven names and their Exploit abilities come from a PCGamer preview, and our companion page labels them as reported rather than confirmed.
