Owlcat Games has released the "Undercover on Ganymede" gameplay trailer for its upcoming title, The Expanse: Osiris Reborn.
The reveal provides the first detailed look at the game's combat and exploration mechanics. As a licensed adaptation of the popular sci-fi franchise, the title's success depends on its ability to translate the series' complex political tensions and physics-based space travel into an interactive experience.
The new trailer showcases a specific mission taking place on Ganymede, one of the moons of Jupiter [1, 4]. This location serves as a key setting for the action RPG, which will also feature other iconic locations including Eros, Ceres, Mars, and Luna [4]. The footage highlights the "undercover" nature of the Ganymede mission, suggesting a blend of stealth and direct engagement.
Owlcat Games, in partnership with Alcon Interactive, is developing the title for several platforms [1, 2]. The game is scheduled to launch on PlayStation 5, Xbox Series X|S, and PC via Steam, GoG, and the Epic Games Store [1].
Developers have also confirmed a timeline for players to test the game. A closed beta is scheduled for late April 2027 [2]. This testing phase will precede the full commercial launch, which is currently set for a spring 2027 release window [3].
The project marks a significant expansion of The Expanse intellectual property into the gaming space. By utilizing the RPG framework, Owlcat Games aims to integrate the detailed world-building of the original series into a playable format.
“The game is scheduled to launch on PlayStation 5, Xbox Series X|S, and PC.”
The announcement of a 2027 release window and a structured beta phase indicates that the project is moving from early development into the polishing stage. By targeting high-end consoles and PC, Owlcat Games is positioning the title as a premium experience intended to capture both fans of the original series and the broader action-RPG market.
