Centipede is a vertically oriented fixed shooter arcade game produced by Atari, Inc. in June 1981. The game was designed by Dona Bailey and Ed Logg. It was one of the most commercially successful games from the video arcade's golden age. The player fights off centipedes, spiders, scorpions and fleas, completing a round after eliminating the centipede that winds down the playing field.
Millipede (stylized millipede in western releases and Milli-Pede in Japan) is a 1982 arcade game by Atari, Inc. and is the sequel to the arcade hit Centipede with more gameplay variety and a wider array of insects than the original. The objective is to score as many points as possible by destroying all segments of the millipede as it moves toward the bottom of the screen, as well as destroying and avoiding other enemies. The game is played with a trackball and a single fire button, which can be held down for rapid-fire.
