"Osiris Reborn: Exploring Mass Effect Comparisons"

by Madison Jun 16,2025

*The Expanse: Osiris Reborn* has generated quite a buzz, with many comparing it to *Mass Effect*—so much so that some are already referring to it as *Mass Effect: The Expanse*. After watching the debut trailer and learning more about the gameplay mechanics, it's not hard to see why this comparison keeps coming up. To Owlcat Games' credit, they openly acknowledge the influence of BioWare’s iconic sci-fi RPG series, but as they clarify, their vision goes beyond simple imitation.

In a recent interview with IGN, Owlcat Games’ creative director Alexander Mishulin and head of publishing Andrey Tsvetkov spoke candidly about how *Mass Effect* shaped their approach to *The Expanse: Osiris Reborn*. While the inspiration is clear, the team aims to deliver a unique experience rooted in the rich universe of *The Expanse*.

A New Story for The Expanse Fans

For longtime fans of *The Expanse*, the game represents an exciting continuation of the story. Owlcat has confirmed that some actors from the beloved Prime Video series will reprise their roles, bringing familiar voices back into the fold. Although specific names are under wraps (and I tried to get details!), the news alone is promising for those who’ve missed the show since its conclusion in 2022.

Why This Crossover Appeal Works

As someone who counts both *Mass Effect* and *The Expanse* among my favorite sci-fi experiences—and a huge fan of Owlcat’s *Warhammer 40,000: Rogue Trader*—this project feels like a convergence of everything I love. Owlcat has already proven its ability to craft deep, narrative-driven RPGs with complex characters and meaningful choices. Now, they’re applying that expertise to a universe praised for its realism and political intrigue.

Could *Osiris Reborn* be the perfect overlap between *Mass Effect*, *The Expanse*, and Owlcat’s signature storytelling? Time will tell—but if early impressions are any indication, fans of character-driven sci-fi have plenty to look forward to.
