What is Serious Sam 4 Xbox Series X|S?

Humanity is under siege as the full force of Mental’s hordes spread 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. Croteam returns with a high-powered prequel to the Serious Sam 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.
