About Serious Sam Double D XXL
Serious Sam Double D XXL is a side-scrolling action game in which Serious Sam takes on Mental’s horde across 18 levels in three worlds. You battle bizarre creatures with an arsenal of weapons, including the Gunstacker, which lets you combine weapons and fire them all at once.
Worlds and enemies
The levels span the pyramids of ancient Egypt, the volcanic chaos of Pompeii and the jungles of prehistoric Earth. You face classic enemies such as Headless Kamikazes, Gnaar and Biomechanoids, alongside new foes including Chimputees, Vuvuzelators and Femikazes. Four bosses await in showdowns across the game.
Weapons and challenges
The Gunstacker lets you stack any combination of weapons on top of one another. You can combine, for example, two shotguns with a laser gun and grenade launcher, or four chainsaws with a flamethrower, then fire the entire stack at once.
Challenge rooms pit you against waves of attacking beasts, and dozens of secrets are hidden throughout the game.
