Evaluation

Serious Sam Double D XXL launched on August 30, 2011, and received a major free upgrade on October 21, 2013 that brought all the new content from the Xbox LIVE Arcade version — new levels, guns, and vehicles — to the Steam version. That XXL upgrade appears to be the last significant content addition to this game specifically. In June 2024, the developer (Mommy's Best Games / Nathan) posted on the game's Steam page to announce their next project, ChainStaff, explicitly framing it as "my next game" and thanking players of Serious Sam DD XXL. ChainStaff released on April 11, 2026, and received a free Hard Mode update on June 1, 2026. These posts appeared on Serious Sam DD XXL's Steam news feed but are about an entirely separate game. There is no indication of any planned new content for Serious Sam Double D XXL itself — the developer has moved on to new projects. The game shipped as a complete product, received one major post-launch content upgrade in 2013, and has had no further content additions since. Anyone waiting for this game to be "done" before playing can consider it complete.

About this game

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.

Key Features

  • 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. Clash against Mental’s army across 18 levels in three sensational worlds from the pyramids of ancient Egypt to the volcanic chaos of Pompeii to the harsh jungles of prehistoric Earth.

  • 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. Two shotguns on a laser gun and grenade launcher? Of course. Four chainsaws and a flamethrower? Yes, please.

  • Legions of Bizarre Beasts: Clash against classic Serious Sam enemies like Headless Kamikazes, Gnaar, and Biomechanoids or gun down all new monstrosities like the insane Chimputees, oddball Vuvuzelators, and the surprisingly sexy Femikazes. Prove your worth and take down four amazingly unique bosses in epic showdowns full of carnage!

  • Challenge Rooms and Serious Secrets: Keep the action coming with a battery of action-packed challenge rooms filled to the brim with waves of attacking beasts! Get really serious and try to uncover dozens and dozens of secrets hidden throughout this wild world!
