Galaxian, while not an official sequel to Space Invaders, was its spiritual successor. Like Space Invaders, in Galaxian the player controls a ship which shoots at aliens flying in formation. However, in Galaxian there are no shields for the player to hide behind, and the aliens leave formation to attack the player.
Galaxian was the first game to feature multi-color sprites. It was created in 1979 by Kazunori Sawano, Kōichi Tashiro and Shigekazu Ishimura for Namco and distributed in North America by Midway.
