These modding tools will be available in the Serious Editor 2021 and powered by the Serious Engine. They are now available on Steam and will follow a full Steam Workshop integration later on.

“Modders have always been the backbone of our community, expanding Serious Sam games with crazy modifications of all shapes and sizes. Some of the total conversion mods we have played throughout the years were absolutely impressive and have kept our games alive for years,” said Davor Hunski, Serious Sam 4 project lead and CCO at Croteam. “We can’t wait to see what the modding community has in store for Serious Sam 4.”

The Serious Editor latest version will come with new improvements and tech features like the new terrain editor, improved battle systems, vehicle support, and upgraded scripting tools. These will provide modders with everything they need to make their own content for the game.

As a sign of appreciation for the fans who still support the franchise, the team is offering big discounts on several of their titles on Steam.


Serious Sam 4 is a high-powered prequel to the legendary FPS series that scales up chaos to unprecedented levels. The classic Serious Sam formula is revamped by putting an unstoppable arsenal up against an unimaginable number of enemies that requires players to circle-strafe and backpedal-blast their way out of impossible situations.

Key Features:

  • HORDES OF INVADERS – The iconic cast of alien invaders returns with some new reinforcements! Fight your way through unbelievable numbers of Mental’s minions, including the iconic Headless Kamikaze, Beheaded Rocketeer, Kleer, Scrapjack, Werebull, and Khnum! Square off against brand new enemies and towering monsters like the frantic Processed, repulsive Belcher, the hard-hitting Zealot, and more.
  • EXPLOSIVE ARSENAL – Armed with a slew of devastating weapons, pick your tool for any situation. Lay waste to Mental’s Horde using the powerful double-barreled shotgun, the punishing minigun, the powerful chainsaw launcher, a brand new auto shotgun, and the iconic cannon. Upgrade your toys, and enjoy the violent beauty of the lock-on rocket launcher, and the mighty laser beam of death.
  • COOPERATIVE MAYHEM – Smash through the action-packed campaign with friends in 4-player online co-op mode! Tackle exciting primary missions and thrilling side quests in modified difficulties for an extra challenge.
  • LEGION SYSTEM – Serious Sam 4 unleashes some of the biggest moments in the series’ history with the new Legion System and battlefields teeming with thousands of enemies!
