The Expanse: Osiris Reborn delivers an original story of survival and loyalty, and significantly expands the world of The Expanse depicted in the TV show and novels.
By the 24th century, humanity has conquered the cosmos. However, life has remained anything but easy. In The Expanse: Osiris Reborn, a story-driven sci-fi Action RPG, you play as a Pinkwater Security mercenary whose brief shore leave on the asteroid Eros spirals out of control. Trapped in a deadly lockdown and drawn into a solar system-wide conspiracy far beyond your control, you’ll have to adapt, survive, taking command of the most advanced ship in the whole of the solar system.
Create and customize your own captain — Earther, Martian, or Belter — and lead a crew of highly-skilled specialists as you face off against escalating threats, political pressure, and a relentless enemy that will stop at nothing to see you dead. In a solar system held together by fragile alliances, every decision leaves its mark.
You’re no hero — just a merc caught in the wrong place at the wrong time, trying to hold your crew together and keep the ship up and running. Your choices will shape your story.
Your companions are more than just mission assets — they are people with their own scars and loyalties. Some chase redemption. Others hide their truths. Over time, your relationships will flourish or deteriorate depending on the choices you make and how you choose to lead. The ship becomes your home — a place where trust is earned, not given.
Fight in third-person utilizing cover-focused gunplay and abilities. Two companions will accompany you into the field while others will support from a distance: disabling systems or drawing the enemies’ attention. You will issue real-time commands and have to adapt quickly to survive the manifold threats the system will throw at you.
Visit iconic locations like Ganymede, Ceres, Mars, and Luna. Walk through ruined habitats and political strongholds mired in unease and tension. Talk to the locals. Uncover secrets. Use your skills to influence what happens next. The system looks different from every planet and from every asteroid. Some are falling apart. Others just hide it better. You may even come across a familiar face or voice that reminds you of just how small the system really is.
Owlcat Games is proud to call The Expanse: Osiris Reborn its flagship project. Owlcat’s roster of titles is nothing short of jaw-dropping, with other major titles including Warhammer 40,000: Rogue Trader, Pathfinder: Wrath of the Righteous, and its newly announced title, Warhammer 40,000: Dark Heresy. Rest assured, the team behind The Expanse: Osiris Reborn is completely separate from Owlcat’s other projects and therefore will not hinder excellence elsewhere.
“We’ve been dreaming about building a sci-fi action RPG of this scale for a long time, and The Expanse is the perfect universe to bring that vision to life,” says Owlcat’s Creative Director, Alexander Mishulin. “It’s a world grounded in realism and complexity, perfect for telling a story the way we like it — mature and character-driven, where your choices truly matter. We are excited to bring this new experience to our players and look forward to sharing more soon, especially knowing how many questions our fans will have.”
“The original Mass Effect trilogy was absolutely an inspiration to the team. It was iconic for the Xbox 360 generation of gamers. Many of us first played it in our teenage years, and it left a lasting impression,” says Yuliya Chernenko, Game Design Producer. “We are building on that legacy and expanding what players anticipate from this experience. Our story is deeply rooted in hard science fiction — one of the core reasons The Expanse universe resonates so well with its fans. The combat reflects the standards of modern action gameplay. The narrative emphasizes political tension and moral complexity. And yes — there’s romance too.”
