|Hardcore 4x4 (initially known as TNN Motorsports Hardcore 4X4 in the US and known as Deka Yonku ~Tough The Truck~ (??4? ~?? ? ????~?) in Japan) is a racing video game developed by Gremlin Interactive for the Sega Saturn, PlayStation and Microsoft Windows. It became available for download from PlayStation Store as a PSone Classic for play on the PlayStation 3 on January 10, 2008, in PAL regions. The game utilizes 3D environments and truck models. The soundtrack features hard rock music. It was the first game to feature vehicles with independent suspension.|
In 1996, ASC (publisher) hired Top Dog Entertainment in Austin, Texas, to develop Hardcore 4x4 II (the second version). The first Sony PlayStation developer in the Americas, Brett Butler, was lead programmer. He travelled to England to collect the game code and world builder tools. Both were defective, so he spent the first month repairing the code base. He then designed new tracks, rebuilt the graphics engine in MIPS RISC R3000 assembly, and hired artists and designers to create new tracks, menu interfaces, and vehicles. The title was completed in late 1997 as Top Dog went out of business shortly after Brett Butler left the company.
