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 revealed a new gameplay video for The Expanse: Osiris Reborn, showing detailed gameplay from a mid-game mission set on the moon Ganymede, where players have to infiltrate a secret base to recover stolen data. Though the mission starts off smoothly, it doesn’t take long for everything to go horribly, catastrophically wrong. 

The trailer showcases the mission on Ganymede, highlighting different aspects of The Expanse: Osiris Reborn: from its cinematic storytelling, to the thrilling action combat, to its exploration and deep dialogue system. The Captain and their sibling J must infiltrate a secret Protogen base to get back their data stolen on Pinkwater station, with their whole team coming together to aid with tech and provide moral support.

At first everything seems to be going according to plan — players explore the base undercover, meet Protogen employees, and try to talk their way into the storage area to retrieve the stolen data. However, things take a turn when an unexpected third party shows up and a bioengineered menace is let loose in the base, forcing the siblings to improvise as they desperately fight their way to make it out alive.
