Test Drive Unlimited (TDU) is an open world racing video game developed by Eden Games and published by Atari for Xbox 360 and Microsoft Windows. Atari Melbourne House developed the PlayStation 2 and PlayStation Portable versions. Being the eighteenth entry in the Test Drive series, Unlimited serves as a reboot of the franchise, discarding the continuity of the previous games. The game features over 125 licensed sports cars and motorcycles and the terrain is modeled after the Hawaiian island of Oahu that features some of roads and highways. It was soon followed by its sequel, Test Drive Unlimited 2 in 2011. A third game and soft reboot, Test Drive Unlimited Solar Crown, is currently under development (with KT Racing and Nacon replacing Eden Games and Atari, respectively), which will release in 2023. Gameplay In the online world of Test Drive Unlimited, players are able to drive both on-road and off-road in free-roam mode, challenging other players in real-time anywhere on the drivable map. It is also possible to drive on small islands outside of the main island. The Xbox 360 version has supported steering wheel controllers since launch. Following the third free update, Test Drive Unlimited supports force feedback wheel controllers such as Microsoft's Xbox 360 Wireless Racing Wheel. The roads are modeled after satellite images of the island of Oahu. There is a spectrum of different terrains including rainforests, mountains, sandy beaches and urbanized areas (featuring the city of Honolulu). It is worth noting however, that other built-up areas on the island are not represented. Although advertising material for the game suggests it to be an exact depiction of the Hawaiian island, numerous government buildings (such as those on Pearl Harbor, Camp H. M. Smith, Hickam Air Force Base), commercial buildings (Ala Moana Center, the convention center, the entire commercial strip in Pearl City and the Pearlridge Center), and notable landmarks (statue of King Kamehameha I, USS Missouri, etc.) are not present in the game. Many roads and highways are also missing or placed far from their real-life counterparts. The ships docked in Pearl Harbor are also in very low detail and do not represent any active or retired USN vessel at all. Single-player game The game begins by purchasing a car and a house. The player is then free to explore the island; as this happens, key locations on the map are revealed. These include car and bike
