Choose from eight tracks, three levels of difficulty, three types of drivers, and four original kart models. Race up to seven players or network opponents in single races and heated tournaments. Push speed, racing skills, and fun to the max. Pick from four realistic outdoor tracks, two adventurous indoor tracks, and two crazy cartoon tracks. You can even use the track editor to construct your own tracks for total racing hysteria. Make them bumpy, flat, twisted, or straight. Choose jumps, bridges, valleys, rough terrain, or a smooth surface. Save your custom-made tracks and load them again and again. Choose from racing or cross karts and customize your machine with one of eight paint jobs. Watch out for kart-crushing obstacles in your path. Extreme weather conditions like fog and rain make the ride even more treacherous. It takes a skilled racer to leave your opposition in the dust and win the Go Kart Challenge.
