Moon Patrol was released in June 1982 in Japan.
Moon Patrol was one of the earliest linear side-scrolling shoot-em-ups and the first game to feature parallax scrolling.
Some graphical glitches:
Shoot an alien ship as it falls and it remains on the screen, with its point total.
Bombs dropped in pits explode on the surface.
Occasionally you'll miss an enemy you appear to hit, but it works the other way around, too.
Occasionally the enemy missiles will hit your very edge and nothing will happen. Don't get too used to this happening, though!
When you jump but still fall in a pit, you always make it halfway between the edge before falling in.
The attract mode course uses its own unique course of gameplay. The screen, however, says 'Beginner course' at the top when the moon buggy is parked at the moon base. The enemies encountered in attract mode are as follows:
Large (double) rock, Large crater, 2 space plants (the second space plant has a rock adjacent to it), Large crater, Small crater, 2 tanks
Uphill climb with rolling boulders, Formation of 3 regular alien crafts, Formation of 3 tri-orb crafts
Downhill descent with formation of 3 elliptical alien crafts
Rocket car, Large crater and small crater adjacent to each other
(Unfortunately, the moon buggy always falls into the large crater that follows the rocket car, so technically the attract mode course ends there. Sometimes the alien craft between points A and C would defeat the moon buggy; other times the moon buggy would mistime its jump over the rocket car. The land mines do not appear in the attract mode).
Mark Robichek holds the official record for this game with 1,214,600 points.
A Moon Patrol unit appears in the 1983 movie 'Joysticks' and in the 1984 movie 'The Karate Kid'.
A Bootleg of this game is called "Moon Ranger
Alfa Records released a limited-edition soundtrack album for this game (R*Type: Irem Game Music - 28XA-199) on January 25, 1988.
