Halloween is a horror video game for the Atari 2600. Although the game was called Halloween, and featured the film’s theatrical poster as its cover art as well as the movie’s main music theme, the game itself never refers to any characters, including the killer, by their names in the film.
Players take on the role of a teenage babysitter who tries to save as many children from an unnamed, knife-wielding killer as possible.In another effort to save money, most versions of the game did not even have a label on the cartridge. It was simply a piece of tape with “Halloween” written in marker. The game contained more gore than the film, however. When the babysitter is killed, her head disappears and is replaced by blood pulsating from the neck as she runs around exaggeratedly. The game’s primary similarity to the film is the theme music that plays when the killer appears onscreen.
The player obtains points in two ways: by rescuing children and taking them to “safe rooms” located at both ends of each floor of the house, and by stabbing the killer with the knife (if it can be located). The player advances a level either by rescuing five children or stabbing the killer twice. The killer gets faster with each level increase, and the game continues until all of the player’s three lives are lost.
