Serious Sam 4

Humanity is under siege as Mental's hordes spread across the world and ravage what remains of a broken civilization. The Earth Defense Force, led by Sam "Serious" Stone and his heavily armed squad of misfit commandos, is the last resistance to the invasion. Croteam returns with a high-powered prequel to the Serious Sam series, escalating the chaos to unprecedented levels. The classic Serious Sam formula is revamped with an unstoppable arsenal, unimaginable enemy numbers, and combat that demands circle-strafing and backpedal-blasting to survive impossible situations.

In Serious Sam 4, humanity is collapsing under the global invasion of Mental's monstrous armies. Sam "Serious" Stone and the Earth Defense Force lead the last resistance, battling overwhelming alien hordes to defend what remains of civilization.
