One significant feature of 4x4 Evo is the online multi-player option. The Dreamcast, PC, and Macintosh versions can compete against each other in 4 player online races.
In addition to the on-line mode of play, there is a single player career mode. The career mode gives you a small allotment of money with which to purchase a truck. You then can compete in races to earn more money for more trucks or performance parts for your current truck.
