The Expanse is getting a bold new chapter this time, in the form of a third-person action RPG called The Expanse: Osiris Reborn. Announced by Owlcat Games, it’s coming to PlayStation 5, Xbox, and PC through Steam, Epic Games Store, and GOG. There’s no launch date just yet, but what’s already on show is enough to get any sci-fi fan’s attention.
This isn’t your typical hero’s journey. You’re a merc, caught in a bad situation that spirals fast. What starts as a quiet shore leave on Eros turns into a full-blown crisis, dragging you into a tangled conspiracy that stretches across the solar system. You’ll need to keep your crew alive, manage the ship, and make decisions that will shape the path ahead.
Welcome to a hard sci-fi world where survival comes first
Set in the universe of The Expanse, the game captures that rough, lived-in feel the show was known for. By the 24th century, people live across Mars, the Belt, and beyond, but power is fragile, and peace is rare. You play a Pinkwater Security officer forced to step up when everything goes sideways.
You’ll create your captain, choose whether they come from Earth, Mars, or the Belt, and take command of one of the most advanced ships in the system. It’s not just about combat. Your crew has its own goals and history. Some are chasing redemption. Others are hiding something. And trust? That’s something you’ll have to earn.
Combat that demands smart choices and quick thinking
The Expanse: Osiris Reborn Gameplay blends third-person, cover-based shooting with real-time squad tactics. You’ll take two companions into the field, while others help from afar, disabling tech or drawing enemy fire. Every mission feels dynamic, and the mix of gunplay and ability usage keeps things from feeling stale.
Back on the ship, things don’t get much easier. Relationships evolve based on how you lead and what decisions you make. Dialogue, diplomacy, and the way you treat your team all feed back into the story. It’s a proper RPG experience, just wrapped in a modern action layer.
Explore familiar locations across the system
If you’ve seen The Expanse, you’ll feel right at home. The game takes you to places like Mars, Luna, Ganymede, and Ceres. You’ll walk through crumbling cities, high-security facilities, and political hotspots full of tension. These locations aren’t just window dressing; they’re part of the narrative, filled with people to meet, secrets to find, and decisions that matter.
The world reacts to your background. What you see, how people treat you, and what options are available depend on where you’re from and the choices you make. And yes, there may be a few familiar voices or faces along the way, tying it all back to the wider Expanse lore.
The Expanse: Osiris Reborn marks a big step for Owlcat Games, moving away from their isometric roots and diving into fully-fledged third-person action. But if what they’ve built so far is anything to go by, they haven’t left behind what made their games work: choice, consequence, and deeply personal stories.
There’s no release window yet, but we’ll be watching closely. This might just be one of the most exciting sci-fi RPGs on the horizon.
