Test Drive Unlimited 2 includes a variety of roads on the island of Oahu, which returns from the first game, and the island of Ibiza. The game features three main vehicle categories, with each vehicle also belonging to a subcategory depending on quality – A for modern asphalt cars (A7 to A1), B for off-road vehicles (B4 to B2), which is a new feature in Unlimited 2, and C for classic cars (C4 to C1), with an additional M category for motorcycles (included in DLC). The vehicle subcategory is noted in the form of a number; the lower the number, the higher the quality. The plot revolves around the Player's customizable avatar, who is offered the chance to enter a series of tournaments and progresses through the game in order to eventually become the winner of the Solar Crown by defeating a number of NPCs in various races.
