Description taken from PC version of this game

4x4 EVO offers players the chance to race customizable off-road vehicles through sixteen different tracks. Each track has its own music score and is designed to offer racers new and unique challenges. Successful racers use their prize money to purchase improvements for their vehicles, such as a higher performance exhaust system, an improved suspension, or special off-road racing tires.

In addition to the PC release, versions of 4x4 Evolution are available for Macintosh systems and for the Dreamcast. In an innovative development, the game is designed so that players with any version of the game can compete against one another online, regardless of which platform they use. ~ T.J.
