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.
