WarGames: Defcon 1 is a video game for the PlayStation and Microsoft Windows developed by Interactive Studios and co-published by MGM Interactive and Electronic Arts. Although both versions possess the same missions and content, the PlayStation version is a tactical vehicle-shooting game while the PC version is a real-time strategy game. The game is loosely based on the movie WarGames; the story was scripted by John Badham, director of the original film.
