Need for Speed: ProStreet brings the underground street-racing scene into the light with sanctioned competitions held across the globe. Multiple events are held on such real-world tracks as Tokyo's Shuto Expressway, Willow Springs, and the Autobahn. The goal throughout each point-to-point or closed circuit course is to be crowned "street king" by defeating rivals in various challenges. Both cosmetic and performance enhancements are available to tune cars, and a real-time damage system means prized vehicles can be totaled during races. Licensed cars include models from Nissan, Subaru, BMW, Ford, Audi, Acura, Chrysler, and other manufacturers.The PSP version has a few key changes from the console games. "Driver Persona" influences the game's degree of difficulty, with players able to choose from the following driving styles: Speed king, Weekend Warrior, and Adrenaline Junkie. An optional racing line called "Driver Intuition" can help new players learn the optimal route through each course. Play modes include Speed Trap, where the goal is to zip through checkpoints at high speeds, Knockout, which eliminates the last driver to cross a checkpoint, and Time Attack, where drivers attempt to reach each checkpoint before time expires. Up to four players can compete online or locally via wireless connection.
