Play Metal Slug 3 Online

Metal Slug 3 was originally an arcade game by SNK, later made available as a Flash Classic. It belongs to that era of pixel-art run and guns where every frame was packed with detail. You control a soldier from the Peregrine Falcon Squad, fighting through a bizarre war against the Rebel Army and an unexpected alien threat.

You run, jump, and shoot across varied environments, from submarines to outer space. The main goal is simply to survive each stage and defeat the boss at the end. Key mechanics include piloting different "Slug" vehicles, like the tank or camel, which change your firepower and mobility. You also collect weapon power-ups, such as the Heavy Machine Gun and Rocket Launcher, to clear dense enemy crowds. The pacing is relentless, with enemies and hazards filling the screen, and the difficulty is notoriously high, demanding quick reflexes and memorization. It feels chaotic and satisfying when you finally beat a tough section you've been stuck on.
