Press Release

Soon, fans of The Expanse: Osiris Reborn will be able to don the armor of a Pinkwater mercenary and experience part of the game themselves. Starting April 22, the closed beta will be available on Steam, Xbox Series X|S, and PlayStation 5 to everyone who purchases the Collector’s Edition or Miller’s Pack on the website. The closed beta will give players a feel for the game’s combat, movement in the zero-g environment, and dealing with life and death on a remote space station. Additionally, Owlcat Games revealed that the game will launch in Spring 2027 on PC (via Steam, Epic Games Store, and GOG) and on Xbox Series X|S and PlayStation 5, with a Day 1 launch on Xbox Game Pass. Fans can wishlist the game now.

The Expanse: Osiris Reborn is a story-driven action RPG set in The Expanse universe with focus on companions, player choices, and dynamic third-person combat. As a Pinkwater Security mercenary who survives a catastrophic incident on Eros, players have to build a team to fight back against Protogen and their experiments. Though the game is set in the same universe as the books and show, it focuses on its own story and characters.

The beta will allow players to explore a remote space station belonging to their employer Pinkwater Security in the wake of escaping from the catastrophic events on Eros known from the books and TV series. Along with exploring this new environment, they will be able to interact with its inhabitants and experiment with dialogue options and choices. Once the masterminds behind the attack on Eros catch up to them, they will also experience the combat and upgrade mechanics first hand.

Owlcat aims at incorporation valuable player feedback from the beta into the final game. 

The beta launches on April 22nd on Steam, Xbox Series X|S, and PlayStation 5. It will be available for founders who purchased The Collector’s Edition or Miller’s Pack, and will run until the game’s launch in Spring 2027. Founder’s Packs can be purchased on the official website. Since the beta is a work in progress, performance may vary and won’t reflect the final quality of the game. On consoles, playing on Xbox Series X or PlayStation 5 is recommended.

The Expanse: Osiris Reborn will launch Spring 2027 on PC (via Steam, Epic Games Store, and GOG), and on Xbox Series X|S and PlayStation 5. Fans can wishlist the game now.

Characters

As your identical twin, J's appearance and gender are based on your custom character's—but they very much have a personality all their own, acting as your impulsive but loyal right hand.

Exploit: Precision

A loud and boisterous combat medic who lost his medical license back on Earth and jokes that he was kicked out before he ever got to take the oath. In combat, his tough armour and experimental stimulants make him a surprisingly aggressive threat.

Exploit: Malfunction

The team's sniper, scout, and expert infiltrator, Regina's guarded personality makes it tricky to piece together her true past and agenda—but it's clear she sees your character as a valuable ally on her mysterious quest.

Exploit: Precision

Every sci-fi crew needs a snarky hacker, right? Having abandoned corporate life to become a free agent, Aleesha seeks out complicated problems and unsolvable enigmas to push her brain to its limits—while deploying drones and subverting enemy systems in battle.

Exploit: Cyber-attack

This youthful, optimistic, chatty Belter yearns to prove herself and achieve something truly great. In a fight, she provides combat support—armoured enough to take a hit, but mobile enough with her submachine gun to lay down a steady stream of mid-range covering fire.

Exploit: Demolition

After growing disillusioned with the UN military and then private security too, this beefy soldier chose the mercenary life. He's principled, and troubled by past tragedy… though not so much of either that he won't happily charge into the thick of things with a shield and a shoulder-mounted autocannon.

Exploit: Demolition

Calm and collected, Zafar chooses his words carefully—and can be surprisingly poetic when he does speak. In battle, he puts pressure on the enemy with deployable turrets and EMF devices that short out enemy equipment, leaving them vulnerable to attack.

Exploit: Malfunction
