After 25 Years, There's More Than One Sam
Serious Sam: Shatterverse launches August 31, 2026 on PC (Steam), PS5, and Xbox Series X|S, with Xbox Cloud Gaming support. Arriving for the series' 25th anniversary, it isn't a one-off commemorative release — it rewrites the franchise's core loop. The old formula of a lone gunman shredding thousands of enemies is flipped into a co-op roguelite for up to five players.
Development is handled by Behaviour Interactive, not original series studio Croteam. Behaviour is the team behind Dead by Daylight, with years of experience running co-op and asymmetric multiplayer as a live service. The project proceeds with Croteam's blessing, and publishing duties fall to indie stalwart Devolver Digital.
Setup: Uber Mental Shattered the Walls Between Worlds
The story begins with recurring nemesis Uber Mental. His maniacal machinations have fractured the walls between universes, and that rift — the "Shatterverse" — scrambles the multiverse. The result: multiple Sams, each pulled from a different dimension, summoned into one place. Players control these alternate Sams, working together to repair the broken multiverse.
That premise isn't just lore dressing; it's the backbone of the design. "Multiple Sams" justifies five-player co-op and per-character variety, while "a rift in reality" gives the roguelite's randomized, repeatable structure a narrative reason to exist.
What Changed: From One Hero to a Party
Classic Serious Sam was a textbook "arena shooter" — wide-open spaces, no tight corridors, and a single player clearing waves of enemies swarming from every direction. Shatterverse keeps that skeleton and adds two new axes.
- ▶Co-op-first design: solo play is possible, but the game is built for up to five players clearing the rifts together
- ▶Roguelite structure: run-to-run variation and acquired upgrades drive repeat play
| Aspect | Classic Serious Sam | Shatterverse |
|---|---|---|
| Core loop | Single-player arena shooting | Co-op roguelite |
| Players | Mostly 1 (some co-op) | 1–5 |
| Repeatability | Fixed campaign | Run-based |
| Developer | Croteam | Behaviour Interactive |
The identity — frantic, overwhelming firefights against sheer numbers — stays intact. What changes is how you consume it: from a solo campaign to repeatable sessions with friends.
The Team-Up: Why Behaviour × Devolver
Behaviour holding the keys instead of Croteam is worth noting. Through years of running Dead by Daylight as a live service, Behaviour has banked expertise in multiplayer matchmaking, seasonal content, and co-op balancing. A co-op roguelite maps cleanly onto that skill set.
Publisher Devolver Digital has long championed distinctive mid-size titles. Serious Sam's B-movie humor and excessive action tone sit comfortably within Devolver's sensibility. The pairing reads less like a big-budget reboot and more like a strategy to reinterpret a brand asset in a co-op genre and reach a new audience.
Platform & Price Check

As of writing, a final price is not yet confirmed on the Steam store page. Given the scope of a co-op roguelite and Devolver's usual pricing band, a tier below a mainline numbered entry is plausible — but until it's official, checking the store listing is the safe move.
Reader Checklist
| Item | Status |
|---|---|
| Release date | August 31, 2026 |
| Localization | Confirm on the store page |
| Co-op | ✅ Up to 5 players |
| Best for | Players wanting a co-op FPS to grind with friends |
| Hold off if | You wanted a classic solo arena campaign |
If you remember Serious Sam as a solo bullet-hell shooter, factor in that this entry's center of gravity has moved toward co-op and repetition. Conversely, for anyone who enjoys the run-based loops of Risk of Rain or Dead Cells and wants that in an FPS, this could be an appealing entry point.
GamePeak Takeaway
Shatterverse isn't a nostalgic victory lap for the 25th anniversary — it's an experiment that transplants the Serious Sam brand into a modern genre grammar: the co-op roguelite. Whether the two variables here — a studio change (Croteam to Behaviour) and a structural shift (solo to party) — expand the franchise or alienate its base will be settled in the early reactions right after the August 31 launch.
