WarGames is a 1984 video game developed by Coleco for the ColecoVision. The game's goal is to defend the United States against nuclear attack, much in the style of a less frantic "Missile Command". The principal designer was Coleco staffer Joseph Angiolillo.
The game was directly inspired by MGM's 1983 film "WarGames", but instead of depicting the film's events, adapts its iconic NORAD scene into playable form. It is one of a handful of games that feature waging nuclear war, and one of the few without an aim of winning it.
