Ghostbusters Commodore 64

Ghostbusters is a licensed game produced by Activision based on the  movie of the same name. It was designed by David Crane, produced by  Brad Fregger, and released for several home computer platforms in 1984,  and later released for various video game console systems, including the  Atari 2600, Sega Master System and NES.

Most versions of the game had a similar basic format to the initial  Commodore 64 and Atari 800 game, which Crane wrote in six weeks.  He based it in part on an incomplete game called Car Wars featuring  armed automobiles in a city; this led, for example, to the  "ghost vacuum" on the Ecto-1, something not present in the film.  Activision obtained the license early in the film's production,  and most of the game was finished by the time Crane watched the film.  While pleased with the game, Crane later stated that he regretted not  being able to include a better victory screen. The last week of  development was spent on the opening screen which plays the Ghostbusters  theme. The game was later ported to the Spectrum, Amstrad CPC, and MSX.
