Trailer, Steam, Official Announcement, and Key Art

A Simultaneous PC and Console Release
Serious Sam: Shatterverse will arrive on PlayStation 5, Xbox Series X|S, and PC on August 31.
The PC edition is listed through Steam and Microsoft’s Xbox ecosystem. Xbox Play Anywhere is supported, allowing eligible purchases and progress to be used across Xbox consoles and Windows PC under the same account.
The PS5 version supports solo play without requiring an online cooperative session. Up to five players can join online, with PlayStation Plus required for console multiplayer.
DualSense vibration and trigger effects are also supported. Resolution modes, performance targets, and PS5 Pro enhancements have not been detailed.
Pricing, editions, early-purchase bonuses, and preload arrangements remain unannounced.
Multiple Sams Unite Against Uber Mental
Uber Mental’s actions have shattered the walls separating multiple universes. Alternate versions of Sam Stone are consequently fighting the same war.
Players join the Serious Program, a multidimensional force attempting to oppose Uber Mental and repair the Shatterverse.
Each team travels through unstable realities to finish battles that other Sams failed to win. Mental has already defeated the hero across several timelines and placed his forces throughout the fractured multiverse.
Progress requires defeating five of Uber Mental’s lieutenants. Each serves as a major boss pursuing complete annihilation.
The multiverse premise allows several forms of Sam to share one battlefield while retaining the humor and short combat remarks associated with the series.
Serious Sam Becomes a Roguelite
Shatterverse replaces a conventional linear campaign with repeated runs whose conditions, rewards, and threats can change.
Its individual arenas are handcrafted, while the route connecting them shifts procedurally. Enemy encounters, opportunities, portals, and modifiers can therefore vary between attempts.
Players collect boons during a run to create stronger or more specialized builds. Run modifiers may change the rules, offer a particular advantage, or add new risks.
Unstable anomalies and hidden portals create high-risk routes. Entering them may rapidly improve a team’s power or end the current attempt.
Death does not erase every form of progress. Permanent upgrades earned across runs expand future possibilities and provide access to new strategies.
Large Weapons and Larger Enemy Waves Remain
The roguelite structure does not remove the core identity of Serious Sam. Large arenas remain filled with enemies applying almost constant pressure.
The arsenal combines recognizable weapons from earlier entries with new equipment designed to eliminate crowded formations.
Mental’s army includes returning creatures and new monsters created for Shatterverse. Their formations force players to move, fire, dodge, and search for temporary space throughout each battle.
Cooperative play allows five Sams to divide enemy attention, combine their builds, and support one another as the screen becomes increasingly crowded.
The complete solo balancing model and differences in enemy numbers between solo and multiplayer have not been explained.
Behaviour Interactive Leads the New Entry
Behaviour Interactive, the studio widely known for Dead by Daylight, is developing Serious Sam: Shatterverse.
Croteam is not the project’s primary developer, although it remains connected as the creator of Serious Sam and has supported this new interpretation.
Behaviour is retaining the fast combat, open arenas, humor, excessive weaponry, and large enemy counts associated with the franchise. Its additions focus on run-based progression, build construction, modifiers, and five-player cooperation.
Shatterverse is a new title rather than a remaster, remake, or expansion for Serious Sam 4.
Players interested in testing it before launch can visit Steam and request access to the Serious Sam: Shatterverse Playtest. Availability and participant numbers may change during development.
Why This Matters
1) Serious Sam is now designed around five-player teams
The unusual party size creates room for larger encounters and several builds operating together.
2) Each run can create different conditions
Boons, modifiers, anomalies, and hidden portals reduce the likelihood of every attempt following the same structure.
3) Failure still creates progress
Permanent upgrades make death part of the process of expanding future builds and strategies.
4) The classic formula remains visible
Its arenas are still large, enemy numbers remain high, and survival continues to depend on movement and oversized weapons.
