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 pleased to introduce the new default face and voice of The Expanse: Osiris Reborn’s male protagonist.

The Captain and by extension his twin brother J received a new standard design that makes them fit into the world of the Expanse more organically. Furthermore, Blythe Melin has joined the team as the male Captain’s and J’s new voice.

While the main character in The Expanse: Osiris Reborn is fully customizable, it is still important to have a default look players can use as a basis for their own captain. The developers have redesigned the male captain’s model to give him a less standard military personnel design with more detail and polish for players to work with. His handsome appearance is also matched by his new voice, brought to life by voice actor Blythe Melin, who previously worked on titles like Genshin Impact, Honkai Star Rail, Diablo IV, Ready or Not, and more. Blythe doesn’t just take over as the captain, he also voices his more carefree and relaxed identical twin J.

For those looking forward to learning who will voice the rest of the cast, more details about the female protagonist and the other team members will be revealed at a later date.

"Voicing both the Captain and J has been an incredible joy and a unique challenge compared to the rest of my work voicing in video games over the years. TWO, biologically related characters! It presented a difficult task in itself, because I find it very important to make sure neither character felt one-note-ey or too similar to the other. The more a character talks, especially in a multi-path dialogue route like for this game, the harder the task of making characters feel fleshed out while still having their own flavors and mannerisms”, says Blythe Melin. “Playing twins has definitely been tricky, but there is somewhat of an easy divide that can be made between the Captain and J, in that one is an avatar for the player themselves, and the other is a pre-established co-character within the context of The Expanse. This allowed us to give J more of a solidified personality to work off of, with a lot of credit going to the writers and directors."
