The Expanse: Osiris Reborn Marks Owlcat’s Bold Entry into Third-Person Sci-Fi Action RPG

During the Future Games Show, acclaimed CRPG developer Owlcat Games—renowned for Pathfinder: Kingmaker, Pathfinder: Wrath of the Righteous, and Warhammer 40K: Rogue Trader—surprised viewers with the announcement of their first-ever third-person action RPG, The Expanse: Osiris Reborn. Set in the deeply layered sci-fi universe created by Daniel Abraham and Ty Franck, the game presents an ambitious new take on narrative-driven, character-focused gameplay.

A Sci-Fi Epic Unfolding in the Beloved Universe of The Expanse

In Osiris Reborn, players take on the role of a Pinkwater Security mercenary whose short break on asteroid Eros turns into a harrowing fight for survival. Caught in a lockdown and entangled in a vast interstellar conspiracy, players must rise to lead their crew through escalating threats with the aid of the most advanced ship in the solar system.

The title leans heavily into player choice and consequence. Players will create and customize their character—choosing to be an Earther, Martian, or Belter—with each background shaping their interactions and decisions. These choices affect how companions respond, how factions engage, and how the story progresses across critical junctures.

Tactical Combat, Companion Depth, and Classic Expanse Tension

Combat is designed around cover-based gunplay, strategic real-time commands, and team synergy. With two active companions joining the player in missions and others providing off-field support (disabling enemy systems, drawing fire), the battlefield constantly evolves. Owlcat’s system offers flexibility, giving players the ability to adapt their tactics on the fly.

Beyond combat, the game's companion system plays a major role. Each crewmember is uniquely written, with personal quests, secrets, and evolving relationships shaped by the player’s choices. Some seek redemption; others may conceal hidden motives. Every decision can either forge trust or fracture alliances.

Explore the Solar System—And Possibly Meet Familiar Faces

Osiris Reborn will take players across iconic locations from the books and the television series, including Mars, Ceres, Luna, Ganymede, and more. These environments are rendered in atmospheric detail—ruined habitats, political strongholds, and civilian sectors echo with tension and unrest. Dialogue with local NPCs may unlock secrets or influence events, reflecting the deep political and cultural divides at the heart of The Expanse.

Intriguingly, Owlcat has hinted at possible appearances by familiar faces or voices from the original narrative universe, adding yet another layer of immersion for longtime fans.

Release Details and Pre-Order Availability

While The Expanse: Osiris Reborn does not yet have a release date, it has been confirmed for PC (Steam, GOG, and Epic Games Store), PlayStation 5, and Xbox Series X|S. Pre-orders are already live on the game’s official website

Owlcat’s transition from isometric RPGs to third-person action storytelling is a bold move, and The Expanse: Osiris Reborn seems set to honor the depth and nuance of its source material while introducing gripping new mechanics. Will this become the next great sci-fi RPG? Time will tell—but all signs point to a promising launch ahead.
