Based on the console hit, Driv3r for the Gamboy Advanced features a single enormous 'Undercover' game mode which encompasses missions and driving mini-games. The 25 missions tell the tale of a jaw breaking, no-holds-barred undercover cop and master "Wheelman", Tanner, as he infiltrates the local and international underworld. The first 12 missions take place in Miami with the remainder set in the French city of Nice. With over 30 miles of streets to explore in each city, the player is free at any time to take a rest from the missions and go for a casual ride around town, gun in hand, in one of the more than 25 vehicles available. Alternatively they can chose to test their mettle playing one of the driving mini-games, including Slalom, Checkpoint, Trailblazer and Destruction.
