Space Invaders is a fixed shooter in which the player moves a laser cannon, referred to as a "Laser Base", horizontally across the bottom of the screen and fires at a group of alien invaders overhead. The invaders begin as five rows of eleven—the amount differs in some versions—that move left and right as a group, advancing on the shooter by shifting downward each time they reach a screen edge. The goal is to eliminate all the invaders by shooting them. Regardless of how many game lives remaining the player has, the game ends if the aliens reach the bottom of the screen.
