"Osiris Reborn: Exploring Mass Effect Influences in The Expanse"

The Expanse: Osiris Reborn immediately draws comparisons to Mass Effect, with its cinematic sci-fi storytelling, deep character interactions, and expansive universe exploration—so much so that some are already dubbing it Mass Effect: The Expanse. After viewing the debut trailer and diving into the game’s mechanics, the resemblance is unmistakable. Yet, rather than shy away from the comparison, Owlcat Games fully embraces the influence of BioWare’s iconic series.

In a candid interview with IGN, creative director Alexander Mishulin and head of publishing Andrey Tsvetkov openly acknowledge Mass Effect as a key inspiration. However, they emphasize that Osiris Reborn is not a mere imitation—it aims to carve its own identity within the sci-fi RPG genre.

For fans of The Expanse, the game delivers a thrilling continuation of the universe. The upcoming title features a brand-new narrative, enriched by the return of select actors from the beloved Prime Video adaptation. While Owlcat remains tight-lipped about specific casting details, the confirmation alone is a major draw for fans still longing for more content since the show’s conclusion in 2022.

Beyond nostalgia, Osiris Reborn represents a compelling convergence of influences. As a devoted fan of Mass Effect, The Expanse, and Owlcat’s critically acclaimed Warhammer 40,000: Rogue Trader—a standout in modern cRPG design—the potential of this project is undeniable. Could Osiris Reborn be the perfect intersection of Mass Effect’s narrative depth, The Expanse’s gritty realism, and Rogue Trader’s rich RPG mechanics? The signs point to yes.
