Side-scrolling Sam goes full chaos with the Gunstacker system, letting you bolt every weapon together into one ridiculous firing squad. It's dumb, loud, and completely aware of itself.

Serious Sam Double D XXL is a 2D side-scrolling shooter built around one central, gloriously stupid idea: the Gunstacker. Instead of swapping between weapons, you physically bolt them on top of each other and fire them all simultaneously. A shotgun under a chaingun under a flamethrower under a laser cannon. The game doesn't ask if this is a good idea. It already knows the answer and commits completely. Mommy's Best Games, a small independent studio, made this as a spin-off from the main Serious Sam universe, and it carries that franchise's core philosophy of non-stop enemy pressure and zero narrative pretension. Waves of the series' signature grotesque enemies pour in from both sides of the screen constantly, and the only appropriate response is to hold down every trigger at once. The level design is functional rather than inspired - mostly flat corridors with occasional platforming that exists to give your feet something to do between massacres. Don't come here for environmental storytelling or layered world-building. This is a shooting gallery wearing a video game costume. What earns the Very Positive rating on Steam is not depth but consistency. The Gunstacker combinations give you genuine decisions to make. Certain loadouts work better against specific enemy types, and there's real satisfaction in figuring out which absurd tower of weaponry handles the next gauntlet. The XXL edition adds cooperative multiplayer and the Serious Sam 3 weapon roster alongside the original content, which meaningfully extends the variety. Co-op especially transforms the game from a loud solo exercise into the kind of chaotic couch session that produces memorable screaming. Where Double D XXL struggles is longevity. The core loop gets repetitive before the game ends, and it does end - the runtime is modest, which is honestly fine for what it is. But the visual presentation is workmanlike rather than distinctive. It lacks the handcrafted pixel poetry of the indie contemporaries it sits beside on a Steam shelf. The soundtrack is energetic and appropriately aggressive without being particularly memorable. This is a game made by people who understood exactly what they were building, optimized it well, and shipped it. There's integrity in that, even if it doesn't leave a lasting aesthetic impression. For the audience this is aimed at - fans of the Serious Sam brand, people who want something to play with a friend that requires zero explanation, or anyone who has ever wondered what happens if you literally stack every gun - Double D XXL delivers precisely what it promises. Kai doesn't usually advocate loudly for this style of design, but there's something honest about a game that has one idea, executes it without apology, and knows when to stop. Kai, Scout Team

Every store in this table quotes us in euros, so the EUR figure is the price the seller actually set, not our arithmetic — which is why EUR is also the currency we rank in. We only list an offer here when the store gives us its price in euros, so nothing in this table is a number we invented.

Pick USD, PLN, GBP, CAD or AUD in the header and we convert from EUR at the European Central Bank reference rate — converted amounts are prefixed with ~. Your bank or the store may apply a different rate at checkout. We never hide offers based on where you are: everyone sees this whole table.

We may earn a commission when you buy games through links on this page — at no extra cost to you. It never affects our rankings or verdicts.
