Ghostbusters was published by Sega and developed by Compile for the Mega Drive/Genesis on June 29, 1990. It is unrelated to the earlier Activision game (though their name still appears in the copyright screen), and is instead a run and gun game in which the player takes control of squat cartoon representations of three of the four Ghostbusters from the movie, with the noticeable absence of Winston Zeddemore. Four levels are available initially; after they are completed, a fifth level is unlocked, followed by a sixth and final level. Each level contains a number (usually two) of mid-bosses known as "middle ghosts"; after a middle ghost is defeated, it turns into a small green ghost which can be captured for extra money by luring it over a ghost trap. Between levels, money can be used to buy powerups, such as a 3-way shot or recovery items.

The game tells the story of Kurt Hectic, a janitor who reluctantly must attempt to save Earth from an alien invasion of gigantic strip mining city-size vehicles named "Minecrawlers". These Minecrawlers are not only removing all of earth's natural resources, but are also crushing any people and cities that get in their way. Aided by his boss, the (possibly) insane inventor/scientist Dr. Fluke Hawkins, and a genetically engineered robotic two-legged/four-armed dog named Bones (although he prefers Max), Kurt must infiltrate each Minecrawler, and fight his way to the pilot, whom he must then kill before returning to Hawkins' in-orbit space station, the Jim Dandy.
