Space Invaders is an Arcade video game designed by Tomohiro Nishikado, and released in 1978. It was originally manufactured and sold by Taito in Japan, and was later licensed for production in the United States by the Midway division of Bally.
Space Invaders is one of the earliest Fixed Shooters and features two-dimensional graphics. The aim is to defeat waves of aliens with a laser cannon and earn as many points as possible. In designing the game, Nishikado drew inspiration from popular media: Breakout, The War of the Worlds, and Star Wars. To complete it, he had to design custom hardware and development tools.
Space Invaders is a two-dimensional, fixed shooter game in which the player controls a laser cannon known as the Core Cannon by moving it horizontally across the bottom of the screen and firing at aliens. The aim is to defeat five rows of eleven aliens—some versions feature different amounts—that move horizontally back and forth across the screen as they descend towards the bottom of the screen, gradually becoming faster in movement as they get closer to the player. The player must destroy all the aliens in order to progress to the next level, earning points and extra lives along the way by shooting each one down with the laser cannon. Its sometimes known for its odd end to a given set of enemies as the last one sounds more like a typewriter on speed.
Occasionally, a red UFO will fly through the screen from one side to the the other. If the player successfully shoots down this enemy, they will receive a bonus that is higher than those given by the standard aliens.
