The Expanse: Osiris Reborn

Game Description: Brief Overview:

The Expanse: Osiris Reborn is a third-person Action RPG set in The Expanse universe. You’re no hero — just a merc caught in the wrong place at the wrong time. Now it is time to gather a crew and find your own path through the web of lies to leave your mark on the solar system.

Full description:

The universe never tells us if we did right or wrong.

By the 24th century, humanity has conquered space — but that hasn't made life any easier. In The Expanse: Osiris Reborn, a story-driven sci-fi RPG, you play as a Pinkwater Security mercenary whose shore leave on Eros spirals into crisis. Trapped in a deadly lockdown and drawn into a conflict far beyond your control, you’ll have to adapt, survive, and take command of the most advanced ship in the system.

Create and customize your own captain — Earther, Martian, or Belter — and lead a crew of specialists through escalating threats, political pressure, and life-or-death missions. In a solar system held together by fragile alliances, every decision leaves a mark.

Trust isn’t given — it’s earned

Your companions are more than mission assets — they’re people with their own scars and loyalties. Some are chasing redemption. Others are hiding truths. Over time, relationships grow or break depending on your choices and how you lead. The ship becomes your home — a place where trust is earned, not given.

Dynamic third-person combat

Fight in third-person using cover-based gunplay and class-driven powers. Bring two companions into the field while others support from a distance — disabling systems or drawing enemy attention. You’ll issue real-time commands and adapt quickly to survive what the system throws at you.

The fractured world of The Expanse

Visit iconic locations like Ganymede, Ceres, Mars, and Luna. Walk through ruined habitats and tense political strongholds. Talk to locals. Uncover secrets. Use your skills to influence what happens next. The system looks different from every rock. Some are falling apart. Others just hide it better. And sometimes, a familiar name or voice reminds you just how small the system really is.
