A.I. The Circuit [Xbox - Unreleased]
Update: Video is now available!
A.I. The Circuit is a game that was in development at Sleepytime Productions over at Radical Entertainment studios, quite some time before the Xbox launched. This prototype was found on an Alpha Xbox 1 Development Kit, which consists of a modified PC, in a special computer tower. It was found along with several other Radical Entertainment titles.
According to Monokoma over at Unseen64.net, this title may be the third and final of the planned series of games based on the A.I. movie, as the other two titles are known but also went unreleased.
Gameplay consists of what is basically a 3d fighter / brawler. The first character, Al, shoots flames out of the device on his arm, along with standard kicking and grappling. Keep in mind this is all extremely early code, so it doesn't always work all that well.
Below are screenshots taken from the game using the Xbox Software Development Kit. Unfortunately, the game does not always function correctly. The second character in the character select freezes the development box, while the other models seem to load, most if the time anyway. Most of the options in the menu are unselectable, or some that allow selection also cause the box to freeze up. Video will follow sometime after these screenshots.
