Serious Sam was released in 2001 and received numerous awards, including Game of the Year from Gamespot and the Editor's Choice award from IGN. Based on Croteam's Serious Engine 3, Serious Sam HD sticks to the original by sending the hero to the battlefields of various ancient civilizations against Mental's armies. The same speed and action-packed game mechanics and the characteristic humor have been preserved and will shine like new in high definition.

Serious Sam HD is not your mother’s generic, large-scale, orchestral scored, Space Marine-themed epic FPS with dialog that pretends it’s an RPG...instead, Serious Sam HD is a grab you by the jibblies run and gun, twitch FPS: BIG guns, TONS of enemies, 4-Player Online Co-Op and stunningly superfluous HD graphics that rival retail boxed games. You've waited forever but Serious Sam is back from the nether with its award-winning game play that will remind you why you play FPSs in the first place.
