Space Invaders is an arcade video game developed 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 shooting games and the aim is to defeat waves of aliens with a laser cannon to 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.
It was one of the forerunners of modern video gaming and helped expand the video game industry from a novelty to a global industry (see golden age of video arcade games). When first released, Space Invaders was very successful.
Taito has released several arcade sequels that built upon the basic design of the original. The first was Space Invaders Part II in 1979; it featured color graphics, an attract mode, and new gameplay elements, and added an intermission between gameplay. According to the Killer List of Video Games, this was the first video game to include an intermission. The game also allowed the player with the top score to sign their name on the high score table. This version was released in the United States as Deluxe Space Invaders (also known as Space Invaders Deluxe), but featured a different graphical color scheme and a lunar-city background.
