Owlcat Games has unveiled the official announcement trailer for The Expanse: Osiris Reborn, a sci-fi action RPG set in the acclaimed The Expanse universe, during the Future Games Show on June 7, 2025. Launched on YouTube the next day, the trailer showcases a gripping story and Mass Effect-style gameplay, with a confirmed release window of 2026 for PlayStation 5, Xbox Series X|S, and PC (via Steam, Epic Games Store, and GOG).
What’s in the Trailer?
The cinematic trailer follows a Pinkwater Security mercenary caught in a deadly lockdown on Eros station, spiraling into a solar system-wide conspiracy involving the protomolecule. Players will captain a custom character—choosing from Earther, Martian, or Belter origins—and command an advanced ship.
The trailer teases tactical third-person combat with real-time cover mechanics, squad coordination, and companion-driven choices, set in iconic locations like Ceres, Ganymede, Mars, and Luna. Familiar faces from the TV show may appear, with some actors reprising roles.
Unlike Owlcat’s usual CRPGs like Warhammer 40,000: Rogue Trader, this third-person RPG, built on Unreal Engine 5, emphasizes action, narrative depth, and companion bonds, including romance options. Set during the first two-and-a-half seasons of the show (or books Leviathan Wakes to Caliban’s War), it offers a fresh story.
Release Date
No exact release date is set, but 2026 is confirmed, with fans on Reddit speculating a late-year launch.
