Labuba Halloween Infestation is a free online Halloween shooting game where you take on waves of increasingly powerful monsters threatening to ruin the holiday. Playing as a customizable character, you scroll through side-scrolling levels blasting every creature in your path before the stage ends. Three distinct difficulty modes mean the monsters hit harder and move faster the further you push, keeping every run feeling like a genuine challenge.

The real hook here is the Pumpkin Boost system. Scattered through each level, these pickups hand you different temporary powers and abilities that can completely flip how you handle a tough section. Bosses wait at the end of every stage, and they are the biggest, most durable enemies in the game, so burning the right boosts at the right time matters. You can also spend your earnings on new costumes, giving you a reason to keep grinding levels beyond just beating your high score. The game runs smoothly on both mobile and PC, so you can pick up a run on your phone or sit down at a desktop without losing any of the experience.

Fans of Halloween arcade games, side-scrolling shooters, and platform shooting games will feel right at home here. Whether you are searching for a free Halloween shooter to play in your browser, a Labubu-style monster-hunting game, or just a quick arcade shooter with boss fights and power-ups, Labuba Halloween Infestation delivers solid gameplay with no download required.
