Sam “Serious” Stone is back, but this time, he’s brought reinforcements: himself. To mark a quarter-century of circle-strafing and screaming kamikazes, Devolver Digital has revealed Serious Sam: Shatterverse. Developed by Behaviour Interactive, this new entry takes the high-octane DNA of the original 2001 classic and shatters it across multiple dimensions.
A Sam for Every Timeline: The Shatterverse Premise
The plot kicks off with a characteristic stroke of madness from the series’ long-time antagonist, the demi-god of destruction Mental. His latest scheme has fractured the boundaries of reality, creating the “Shatterverse”—a collapsed world where different versions of Sam Stone from across infinite dimensions have been pulled together.
- 5-Player Multiverse Co-op: For the first time, up to five players can team up, each controlling a Sam from a different reality.
- Dimensional Warfare: Players must navigate shifting battlefields, accumulating dimensional buffs and using various modifiers to rewrite the rules of combat on the fly.
- The Hunt for Lieutenants: To restore reality, the “Sams” must systematically dismantle Mental’s five powerful lieutenants guarding the anchors of the Shatterverse.
Classic Carnage, Modern Depth
Despite the multiverse twists, Shatterverse promises to stay true to its roots. The gameplay remains a relentless, high-intensity run-and-gun FPS set in massive, wide-open arenas.
You can expect the return of iconic enemies like the Headless Kamikaze and Gnaars, alongside a host of new dimensional monstrosities. The arsenal is equally diverse, featuring the legendary double shotgun and cannon alongside experimental “Shatter-tech” weaponry that can only be found within the rifts.

A “Serious” Stamp of Approval
The project has received full support from the original creators at Croteam. “Seeing another team bring such a fresh and bold interpretation to the universe we’ve built over two decades is incredibly exciting,” the studio shared.
Behaviour Interactive added that their goal is to honor the 25-year tradition of the franchise while introducing a modern, replayable roguelite structure that keeps the action feeling fresh. With Devolver’s trademark chaotic flair, Shatterverse is shaping up to be the ultimate anniversary gift for fans of old-school shooters.
