Off-Road Challenge is a 3D truck racer, with arcade-style action and unforgiving courses over dirt, mud, and snow. Players can choose from four trucks, with four additional, more powerful "hidden" vehicles available to those who can find them. Courses include "Mojave," "Pike's Peak," "Las Vegas," "El Paso," "Baja," and "Ol' South." Two additional courses must be unlocked for play. As in the game's 16-bit isometric inspiration -- racers such as Ivan "Ironman" Stewart's Super Off Road -- players can upgrade their trucks, if they've got the money. Players earn cash both by collecting icons that appear on the courses, and also by winning races. Money can be spent on better acceleration, speed, shocks, or tires, or on nitros for a quick boost in the races. ~ T.J. Deci, All Game Guide
