Space Invaders

Space Invaders[b] is a 1978 shoot ’em up arcade video game developed by Tomohiro Nishikado. It was manufactured and sold by Taito in Japan, and licensed to the Midway division of Bally for overseas distribution. Space Invaders was the first fixed shooter and set the template for the genre. The goal is to defeat wave after wave of descending aliens with a horizontally moving laser to earn as many points as possible. https://en.wikipedia.org/wiki/Space_Invaders
