Serious Sam 4 elevates the iconic full-throttle gameplay, massive hordes of enemies, and explosive array of weapons to the next level with the power of Croteam's Serious Engine.

Humanity is under siege as the full force of Mental’s hordes spreads across the world, ravaging what remains of a broken and beaten civilization. The last remaining resistance to the invasion is the Earth Defense Force led by Sam “Serious” Stone and his heavily-armed squad of misfit commandos. 

Serious Sam 4 reignites the classic series by improving on the old-school formula. Enjoy the high-adrenaline action combat with an unbelievably destructible arsenal and experience Sam's iconic enemy-annihilating circle-strafing and backpedaling dance-routine on an even bigger scale.

Croteam and Devolver Digital previously announced that Serious Sam 4 would unleash both barrels of chaos on Steam and Google Stadia in August 2020, but it turns out we totally meant to say September 24, 2020.
