The Expanse: Osiris Reborn

The Expanse: Osiris Reborn is a story-driven Action RPG set in the universe of The Expanse. Players create and customise a captain of Earther, Martian, or Belter origin, taking on the role of a Pinkwater Security mercenary whose shore leave on the asteroid Eros escalates into a solar system-wide conspiracy. The captain commands an advanced ship and leads a crew of specialists through escalating political and military threats.

Combat takes place in third-person, using cover-based gunplay combined with character abilities. Two companions join the player directly in combat, while others provide support from a distance, such as disabling enemy systems or drawing attention away from the player. Players issue real-time commands to their crew, requiring adaptation to different combat situations.

The game features companion relationships that change over time based on player choices and leadership style, affecting trust and loyalty within the crew. Players can visit multiple locations across the solar system, including Ganymede, Ceres, Mars, and Luna, each with distinct environments and political situations. Exploration includes interacting with local characters and uncovering information that can influence the unfolding story.
