Test Drive 6 is the sixth game in the Test Drive series and add-ons that started in 1987. The game features 40 sports and muscle cars, and 20 tracks located in various places such as London, Paris, Egypt, Hong Kong, Maui, Rome, Ireland, Tahoe, England, and the Caribbean.
The gameplay involves racing through these environments, with unique sound effects for each location. Players can also interact with the environment, breaking objects, avoiding obstacles, and finding shortcuts. The "All-Units" AI system allows the police to work together to take players down, adding an extra layer of challenge. Additionally, there is an economic racing system that lets players purchase, upgrade, and stockpile cars in their custom garage.
The game also features high-impact collisions, unpredictable cross traffic, and split-screen head-to-head racing for the PlayStation and Dreamcast consoles.
