Serious Sam 4 revives the classic FPS series in an energetic prequel with a massive explosives arsenal, intergalactic carnage, and perfectly places jokes. Humanity is under siege. Mental's hordes spread over earth to destroy the remains of a broken and beaten civilisation. The last remaining resistance to the invasion is the Earth Defence Force, led by Sam Serious Stone and his heavily armed unit of weird commandos. Destroy Mental's horde with the powerful double-barrelled shotgun, the devastating Minigun, the brutal chainsaw launcher, a brand new automatic shotgun and the iconic cannon.
