Tron Unlockables (Xbox 360)

Since games play a central role in the film, many video games based on Tron have been produced over the years. Atari, Inc. had plans to develop a real Space Paranoids game, but this was canceled due to the video game crash of 1983, along with arcade adaptations of Superman III and The Last Starfighter. In 1982, Midway Games released the Tron arcade game, which consisted of four mini-games based on sequences in the movie. This game earned more than the film's initial release.

In 1983, Midway released Discs of Tron, a sequel that focused on disc combat. Mattel Electronics released three separate Tron games (unrelated to the arcade game) for the Intellivision game console in 1982: Tron Deadly Discs, Tron Maze-A-Tron, and Tron Solar Sailer. Deadly Discs was later ported to the Atari 2600 (along with an original Tron game for that platform, Adventures of Tron), and a version also appeared for the short-lived Aquarius home computer. A special joystick resembling the Tron arcade game joystick was also created as a free giveaway in a special pack that included both Atari 2600 Tron video games. (Wikipedia)
