Colors

Colors is an unreleased game for the failed Gizmondo that would have tapped into the handheld’s GPS functionality to allow the player to (magically?) play in his or her real-life location. During development, it apparently shifted from a first-person shooter to a GTA-inspired third-person shooter. Soda machines appeared in both incarnations. [Source]

Sorry about the quality of the second screenshot; it’s difficult to track down clear images of unreleased games on handheld systems nobody owned. ? [Source]
