The Expanse: Osiris Reborn: Map Size and Regions
The game utilizes a semi-open world 'Hub and Spoke' model. Major hubs include the Belter slums of Ceres, the militaristic citadels of Mars, and the luxury districts of Luna. Each hub contains multiple detailed mission sub-zones. Environmental diversity ranges from claustrophobic, dark asteroid tunnels to the vibrant agricultural domes of Ganymede. The 'Gemini' serves as the primary mobile hub connecting these distant solar system regions.
The Expanse: Osiris Reborn: Post-Launch Content / DLC
Owlcat has confirmed significant post-launch support including story expansions ('The Gate' DLC) and additional companions. Cosmetic skin packs for the Gemini and crew are also planned. There are no plans for microtransactions or battle passes.
The Expanse: Osiris Reborn Skills & Upgrades Overview
The system is classless and fluid. Players invest in attributes like Science, Persuasion, and Tactical Combat. Skill checks are non-RNG; success is guaranteed if your point value meets the threshold. Combat upgrades involve weapon-specific proficiency and gadgets like tactical drones or high-fidelity visors. The 'Exploit System' allows players to upgrade companion-specific synergies, enabling massive environmental combo attacks based on the squad's composition.

Single-player only. However, it supports 'Xbox Play Anywhere' (cross-buy between PC and Xbox) and features cross-save functionality between PC, PS5, and Xbox Series X/S via an Owlcat account.
The Expanse: Osiris Reborn Other Features & Info
- labelMultiplayer Modes
None. The game is designed exclusively as a single-player narrative experience to ensure maximum focus on player choices and the 'Mass Effect-style' cinematic story.
- labelUser Interface
A diegetic 'augmented reality' HUD that projects ammo and health data through the protagonist's suit visor. In Zero-G, the UI includes a vector-alignment tool to help players maintain orientation. Menus are inspired by 24th-century tech terminals seen in the television series.
- labelSound and Music
Features a realistic vacuum-audio mode where sound is muffled and vibrations travel through the suit/boots. The score is a blend of orchestral and electronic synth, matching the gritty tone of the show. Original series actors reprise their roles, including voice work for key canonical cameos.
- labelGraphics and Visuals
Powered by Unreal Engine 5. Highlights include Lumen for realistic space lighting (stark shadows/harsh sunlight) and Nanite for ultra-detailed asteroid surfaces. Environmental destruction allows cover to be chipped away during firefights.
- labelAccessibility Features
Includes text-to-speech, colorblind modes for tactical visors, adjustable Zero-G motion sickness settings, and a 'Story Mode' difficulty. Combat can be paused for tactical planning (though it remains a real-time shooter).
- labelStory and Setting
Set between 'Leviathan Wakes' and 'Caliban's War,' the game explores the fallout of the Canterbury's destruction. Players are thrust into a conspiracy involving the Protogen corporation and the horrifying Protomolecule. The narrative follows a Pinkwater Security mercenary and their twin (J) as they escape the Eros massacre aboard the hijacked 'Gemini.' The game features iconic locations like Ceres, Eros, Luna, and Ganymede, blending established canon with an original, choice-driven mercenary storyline.
- labelTop 5 Weapons (Subjective/Iconic)
- 1. Miller's Revolver: A high-caliber, slow-firing legacy weapon. 2. Spec Ops Assault Rifle: The versatile backbone of Pinkwater mercs. 3. MCRN Rail-Sniper: A Martian-tech rifle capable of piercing light cover. 4. Belter Slag-Shotgun: Brutal at close range with high kinetic impact. 5. Tactical Submachine Gun: Optimized for high-G combat and Zero-G recoil management.
- labelTop 3 Mounts/Companions
- 1. The Gemini: Your mobile hub and stealth-ship 'mount.' 2. Teo’s Medical Drone: A combat companion that deploys stimulants. 3. Michael’s Auto-Cannon: A heavy fire-support companion weapon.
