Humanity is besieged by the Mental hordes that are spreading all over the world and ravaging what is left of a shattered and defeated civilization. The last resistance to the invasion is put up by the Earth Defense Forces, whose vanguard is Sam "Serious" Stone and his heavily armed unit of specific commandos.
Croteam returns in a turbo-charged prequel to the Serious Sam franchise that takes chaos to unprecedented levels.

You must sidestep, circle your opponents, and quickly back out of horribly difficult situations.
