About the game
The Expanse: Osiris Reborn is a third-person action RPG set in the universe of The Expanse. You play a merc caught in the wrong place at the wrong time, then build a crew, keep your ship running and choose a path through a web of lies spread across the solar system. Xbox and developer information position it as a story-driven role-playing adventure with consequential decisions, crew management and combat. Its planned Q2 2027 release is still upcoming, so this page does not infer availability beyond the existing editorial record.
