As most people know, Millipede was the sequel to the arcade smash hit Centipede. Although Millipede never reached the same level of popularity as its multi-legged cousin, it's still a great game in its own right and deserves more recognition. Apparently Atari felt the same way as Millipede was planned for all four of its game systems: 2600, 5200, 400/800, and 7800, but only the 2600 and 400/800 versions ever made it out the door.
