Serious Sam: Double D: XXL is a Serious Sam game that was released for the Xbox 360 and PC. It is an improved version of Serious Sam: Double D.


Serious Sam: Double D: XXL is much like its predecessor. It is 2D and features the same Serious Sam-inspired gameplay that it's predecessor has. Gunstacking will also be in.

However, there are several large differences. First, the game supports local co-op for two players. The second player can drop in at any time by hitting the A button. Second, The second player will control Huff, the guy from the Serious Sam: Double D trailer.

Guns can be upgraded in two ways; ammo or a plain upgrade. Ammo simply increases how much ammo the player can hold. There are several ammo upgrades, but they must be purchased at once. The second upgrade, the plain upgrade, vastly changes how a gun works. For example, the 12 Gauge Shotgun can be upgraded to the Cybernetic Bee, which fires bees that lift enemies in the air and harm them. Upgrades must be purchased with money, which is obtained by killing enemies.

Several new enemies have also been added to the game. Completely new enemies are in, such as the Torcher Kitty, which is a cat in a floating jar of green liquid that spews fireballs from its mouth. In addition, several cannon-fodder enemy types, such as the Beheaded Rocketeer, will have armor in some parts of the game in order to make them more challenging.

Finally, several of the game's levels have been reworked to accommodate the new weapon upgrades and co-op. It is unknown how much had been changed.

Co-op gameplay.

Serious Sam: Double D: XXL contains both single player and local co-op. Local co-op can be played in the campaign levels, and the challenge levels. The second player is Huff.

PC versionEdit

Mommy's Best Games confirmed that XXL will come to the PC as an upgrade to Serious Sam: Double D sometime after the Xbox 360 version was released.

The PC version on Steam will automatically download and upgrade itself, and when starting the game players are given the option of the 2011 original version or the 2013 XXL version.



The levels in XXL are identical to the original version with the exception of the addition of several race-type levels where Sam pilots vechicle to kill enemies for money while avoiding track obstacles. Each act has an additional vehicle stage:

  • Act 1: Rocket Board (vehicle: jet propelled snowboard)
  • Act 2: Dinofighter (vehicle: rocket launching dinosaur)
  • Act 3: Lunicycle (vehicle: dynamite powered unicycle)

In these additional stages Sam loses the use of his weapons and gains control of a vehicle to move through the level. There are no additional secret areas, just stashes of money for upgrades.

Note: XXL adds small silver stashes that contain health and armour upgrades located in secret areas and scattered around. These upgrades increase the limit on your health and armour to 200 each when all collected. Once collected they will reappear on subsequent playthroughs but will not provide an upgrade. The chainsaw is the easiest method to opening these.
