Serious Sam: Shatterverse is a co-op FPS where five players can team up, blast through shifting universes, stack wild boons, bend the rules with run modifiers and hunt the deadliest forces of Sam’s relentless arch-nemesis, the villainous Mental.

Mental’s maniacal machinations have fractured the walls between universes, and now Sams from multiple dimensions must learn to work together to repair the Shatterverse. You’ll travel across shifting universes to finish battles other Sams couldn’t, fighting alongside alternate versions of yourself to defeat the big bad’s five nefarious lieutenants.

While this game is developed by Behaviour Interactive, newcomers to the Serious Sam universe, the developer has the full blessing of series creators Croteam:

Key Features:

• Wield a big, loud, stupid and frankly irresponsible arsenal of weapons, mixing classic Serious Sam guns and all-new toys plucked from the Shatterverse
• High adrenaline run-and-gun FPS combat with big battlefields, non-stop pressure, a lot of backpedaling and perfectly timed one-liners when everything’s on fire
• Leans into Serious Sam’s legacy and pushes it forward with procedurally shifted runs across hand-crafted arenas set in previously unexplored worlds
• Navigate unstable anomalies, hidden portals and high-risk opportunities that can supercharge a run – or end it instantly
• Push forward for greater rewards, unlock powerful modifiers and take advantage of upgrades that permanently expand your possibilities
• Face off against massive hordes of enemies including classic Serious Sam foes and fresh monsters under Mental’s control, all begging to be gibbed

All this and more awaits you in Serious Sam: Shatterverse, launching on PC, PS5 and Xbox Series X|S on August 31, 2026.
