A centipede touching a poisoned mushroom hurtles straight toward the player's area. Scorpions poison every mushroom they touch, but these never appear in the player's movement region. Spiders move across the player area in a zig-zag fashion and occasionally eat some of the mushrooms. The flea leaves mushrooms behind when fewer than five are in the player area, though the number required increases with level of difficulty. Points are awarded for each one of those mushrooms after the player loses a life. A player loses a life when hit by a centipede or another enemy, such as a spider or a flea, causing the game to turn any poisoned or partially damaged mushrooms back to normal whole mushrooms. Every time a centipede is eliminated, however, the next one is one segment shorter and is accompanied by one additional, fast-moving 'head' centipede. When all the centipede's segments are destroyed, a new centipede forms at the top of the screen. This continues until the player has eliminated both the original centipede and all heads. If the centipede reaches the bottom of the screen, it moves back and forth within the player area and one-segment 'head' centipedes are periodically added. The player can destroy mushrooms by shooting them, but each takes four hits to destroy. Thus, more mushrooms on the screen cause the centipede to descend more rapidly. When it hits a mushroom or the edge of the screen, it drops one level and switches direction.

The centipede starts at the top of the screen, traveling either left or right. If the head is destroyed, the section behind it becomes the next head. Each piece then continues independently on its way down the board, with the first section of the rear piece becoming a new head. Shooting any section of the centipede creates a mushroom shooting one of the middle segments splits the centipede into two pieces at that point. The player moves the character about the bottom area of the screen with a trackball and fires laser shots at a centipede advancing from the top of the screen down through a field of mushrooms. The player is represented by a small, 'somewhat humanoid head' at the bottom of the screen, later depicted as a caped, elf-like character on the Atari 2600, Atari 5200 and Atari 7800 cartridge graphics (though described as being a garden gnome in the trivia section of the cell phone interpretation). The player defends against centipedes, spiders, scorpions and fleas, completing a round after eliminating the centipede that winds down the playing field. The game was designed by Ed Logg and Dona Bailey. Others are coming soon.Ĭentipede is a vertically oriented shoot 'em up arcade game produced by Atari, Inc.
