Moon Patrol is an arcade game by Irem released in 1982. It was licensed to Williams for distribution in North America. Moon Patrol is widely credited for the introduction of parallax scrolling in side-scrolling video games. Taito's Jungle Hunt side-scroller, released the same year as Moon Patrol, also features parallax scrolling.
Moon Patrol was ported to the Apple II, Atari 8-bit family, Atari 2600, Atari 5200, Atari ST, Commodore 64, VIC-20, MSX, IBM PC, TI-99/4A, and Tandy Color Computer. Many of these were published by Atari's Atarisoft label. Ports to the ColecoVision and ZX Spectrum were not released.
