IGN released an official gameplay trailer for The Expanse: Osiris Reborn, a third-person action RPG set within The Expanse universe [1].

The reveal provides the first detailed look at the game's combat and environment, signaling a major expansion of the franchise into the RPG genre. This move allows developers to explore the series' complex political landscape through a new perspective.

The footage showcases a protagonist serving as a Pinkwater Security mercenary stranded on the asteroid Eros [1]. The trailer, which premiered during IGN Live 2026, highlights the atmospheric tension of the setting and the specific mechanics of the mercenary's role [1].

Access to the game is beginning for a limited group. A closed beta was scheduled for April 22, 2026, on Xbox Series X|S for Founders who supported the development process [2].

However, the project has faced internal turbulence regarding its lead character. While the trailer features the Pinkwater Security mercenary, reports from PushSquare and MSN said the main character is being completely recast following negative fan feedback [2].

The gameplay focuses on survival and combat in the harsh environment of Eros, blending the series' hard-science fiction elements with action-RPG progression [1]. The trailer serves as a primary tool to promote the closed beta and establish the story premise for the wider audience [1].

“The Expanse: Osiris Reborn is a third-person action RPG set on asteroid Eros.”

The decision to recast the protagonist suggests that the developers are highly sensitive to community reception early in the production cycle. By utilizing a closed beta for 'Founders' on Xbox, the studio is attempting to stabilize the game's core mechanics and narrative appeal before a full public launch, reflecting a cautious approach to a high-profile licensed property.
