Major Havoc (or The Adventures of Major Havoc) is an upright cabinet vector-based arcade game released by Atari, Inc. in 1983. Major Havoc consists of a number of smaller game experiences played in succession, including a fixed shooter, platformer, and a lunar lander sequence. It was developed by Owen Rubin with some levels designed and tuned by Mark Cerny, who joined the development team approximately a year into the game's development.
