Test Drive Unlimited, distributed by ATARI, is an arcade-style racing simulator that features over 125 licensed sports cars and motorcycles and a terrain modelled after the Hawaiian island of Oahu. The island features over 1600 km of roads and highways. Test Drive Unlimited is the latest installment of Test Drive, one of the longest running racing games ever.

Test Drive Unlimited, the player is able to drive both on-road and off-road, challenging any racers they encounter.

The terrain differs from rainforest and mountains to sandy beaches and Hawaii's capital city, Honolulu.
