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, trying to hold your crew together and keep the ship up and running. Your choices will shape your story.
By the 24th century, humanity has conquered the cosmos, but that hasn't made life any easier. What begins as a brief sojourn on the asteroid Eros reluctantly entangles you in a solar system-wide conspiracy. You will need to adapt to survive and keep your motley crew united in their mission as everything around you begins to fall apart. This is your story. The Expanse: Osiris Reborn offers a truly personal journey that evolves based on the choices you make and the pressures they place on everything you stand for. You begin as a Pinkwater Security mercenary taking some routine shore leave on Eros Station, when your much-needed rest is abruptly cut short as chaos erupts and an escalating emergency forces the entire station under strict quarantine. Create and customize your own captain — Earther, Martian, or Belter — and take command of the solar system’s most advanced spaceship as you fight to uncover the truth and reclaim control of your own fate.
