The Expanse: Osiris Reborn – RPG with Choices That Shape the Solar System

A New Chapter in The Expanse Universe

Fans of The Expanse know the series for its political intrigue, planetary conflicts, and small decisions that ripple across the solar system. The same spirit lives on in The Expanse: Osiris Reborn, the latest RPG from Owlcat Games, recently showcased in a closed preview at Gamescom 2025.

In just one hour of gameplay, it was clear: every player choice can lead to massive consequences, with no warning before you change the fate of thousands.

Story Setup and Characters

The game is set between the first two Expanse novels (or roughly the first two seasons of the TV series). Players control a pair of twins working for Pinkwater Security, whose lives spiral into chaos after an encounter with Protogenon Eros.

• Players can customize gender, origin, and starting loadout — from a marksman with a sniper rifle to an officer with an assault weapon.

• The Pinkwater station feels alive, with algae-based food menus, gossiping NPCs, and quirky side quests like “A Purrfect Gift,” where you help a worker named Larry deliver a mysterious package for his mother’s birthday.

The narrative is designed to be accessible for newcomers while rewarding long-time fans with deep lore references.

Gameplay: Choices and Consequences

Tension quickly rises when a Protogen ship arrives, demanding the return of a stolen vessel. The player must choose: flee, negotiate, or fight. A wrong choice can devastate the station, killing countless NPCs.

Combat emphasizes:

• Cover-based shooting

• Interactive environments

• Unique companion abilities

One highlight is an exterior mission in open space. Using magboots, characters walk along the station’s hull with Jupiter looming in the background, creating breathtaking visuals. The silence of space amplifies the drama while firefights in zero-gravity add cinematic intensity.

Exploration and Scope

The demo culminates in a high-stakes escape sequence where your chosen path affects team relationships and future storylines. Afterward, the game expands further, letting you travel across Ceres, Mars, and Luna, with 20–30 hours of branching narrative gameplay.

Why It Matters

With its rich storytelling, dynamic combat, and morally challenging decisions, Osiris Reborn promises to be an epic addition to The Expanse universe. Every small decision can snowball into galaxy-altering consequences — a true hallmark of the franchise.
