One of the main features of Centipede and Millipede is that the games force you to divide your attention between the upper screen with the advancing centipedes/millipedes as well as scorpions, and the lower part of the screen where you had the spiders, any stray centipede/millipede parts, and the ladybugs in Millipede. I played both games on Atari hardware. There was also a NES version of Millipede made by HAL Labs (under Satoru Iwata, no less), which also did the NES Joust and Defender ports, all of them sporting sound and music samples from Punch-Out!! And finally, there was an arcade clone of Centipede called War of the Bugs or Monsterous Manouvers (sic) in a Mushroom Maze, which was made using the Galaxian hardware.
