Need for Speed Underground Rivals Cheats - PSP
In the Nitrous Run Race, if your time is about two to four seconds from expiring, aim the car at the gate and use all the nitrous remaining. Even if the timer runs out, your car will keep going enough without the gas and may pass the gate. If so, the timer will start again and your nitrous tank will be refilled, allowing you to continue with the race.
Complete the last race of a set with a gold medal.
