Serious Sam takes on Mental’s army in a 2D side-scrolling action platformer. The campaign spans 18 levels across three worlds, including ancient Egypt, Pompeii, and prehistoric Earth.
Run, jump, and shoot through levels packed with varied enemies, then face four bosses. The game also includes platforming hazards, hidden secrets, and rooms built around waves of attackers.
The Gunstacker lets Sam attach weapons together and fire them simultaneously. Money collected from enemies can be spent on weapon upgrades, while challenge rooms offer additional combat trials.
Players who enjoy the game often praise the Gunstacker’s over-the-top weapon combinations, the energetic 2D combat, and its comic art and humor. Some also appreciate the level design, secrets, and enemy variety. Reactions are mixed: other reviewers find the action repetitive, the controls or platforming clumsy, and some challenges frustrating.
Serious Sam explodes into the second dimension using everything in his arsenal to battle the abominable legions of Mental’s horde. Pull the trigger to let the heavy ordinance fly in Serious Sam Double D XXL, a completely reloaded version of the indie sensation Serious Sam Double D with all-new missions, weapons, enemies, and challenges. Pile on the firepower with the revolutionary Gunstacker and fire all your weapons at once in a symphony of destruction! All that stands between victory and annihilation is a man in a T-shirt and jeans wielding a great big pile of guns.
Serious Action: Unleash a storm of bullets and flame against an unrelenting horde of bizarre and ferocious creatures hell bent on bringing down the heroic Serious Sam.

Revolutionary Gunstacker: Duel-wielding is for lesser men. Serious Sam Double D’s new Gunstacker allows Serious Sam to stack any combination of weapons one on top another and fire them all at once.
