Moon Patrol is an early colour arcade shooter, released by Irem in 1982.
It was distinctive because you drove a vehicle, at the bottom of the screen, and had to jump over craters and obstacles, as well as shoot aliens in the sky. So you are keeping an eye on the road, while at the same time shooting enemies flying above you. This was a neat innovation at the time and earned Irem some respect.
Moon Patrol was popular and was cloned a lot during the video games boom of the early Eighties.
Back in 1982 the game was very innovative in its use of scrolling graphics. It had backgrounds with different levels of depth, done by scrolling individual layers at different speeds. “Parallax scrolling” they called it. The animation of the moon buggy itself was kinda dinky as well, which gave Moon Patrol a ‘cute’ aspect.
Moon Patrol is definitely worth a mention in the pantheon of old arcade classics.
