Arcade Factory was the 1st stage in the Minus World, representing various arcade and Atari games such as Space Invaders and an early console port of Donkey Kong. The level begins with a narrow tunnel filled with enemies, crushing pistons, conveyor belts and steam vents. The second part of the level is a vertical climb with attacks from passing Space Invaders, and rolling barrels dropped from Donkey Kongs. The level ends with a moderate-speed auto-scrolling section with many of the same obstacles as before.
