All Prototype parts
Get 1,500 respect points from all CPU characters to unlock all Prototype parts.
Arcade bonuses
Successfully complete all the series in Arcade mode, except the Extreme Nitrous
Series, to unlock the Bronze, Silver, and Gold Prototype Challenge Series.
Bouncing car
Get a Corvette Z06 and go to the test track. Start driving backwards, then go to
the curb with the crane sticking over the track and drive into the dirt. You
should see hardened dirt. Drive onto that until you get halfway through the
hardened dirt, then drive off slowly as if you are going back onto the track.
Before you get back on the track your car should start to bounce and shake. When
you come out of it, your car should be badly damaged.
Completion bonuses
Get a 100% completion in Career mode to unlock Prototype mods for all cars in
Career mode and the Extreme Nitrous Series in Arcade mode.
Easy money
Earn 600 respect points from any CPU character. Then, call any character on your
mobile phone. Race for pink slips with one of your less powerful cars. After you
get there, sell it for extra money. Make sure to have more than one car in case
you lose the race.
Flying car
Get a Viper GTS fully tuned and go to the oval track. Drive about 210 mph. When
you are about to turn, turn the other way into the wall. Hit the nitrous and
hold it while still turning into the wall. If done correctly, your car should go
up and fly. You must be in the dirt part of the turn. Try using the nitrous two
seconds before hitting the wall and hit the wall (wire fence) at about a 30
degree angle
