Millipede is a 1982 arcade game by Atari, Inc. and is the sequel to the arcade hit, Centipede. The objective of the game 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. The game is over when the player's last life is lost. Similar to Centipede, the object of the game is to destroy a millipede that advances downward from the top of the screen. The millipede travels horizontally until it either hits an obstacle or reaches the edge of the screen, after which it drops one row and reverses direction. Once it enters the player's gray maneuvering area, it stays there and extra heads appear at intervals until both they and the millipede are destroyed. Shooting a body segment splits the millipede in two, with the rear portion sprouting its own head. A collision with any enemy costs the player one life.
