Tips
Even though your car has brakes, you won't need them in this game.
Use the Practice modes to get a feel for the various cars and tracks.
Focus on the stunts and speed, because the engine keeps the cars on track for many of the outrageous loops and corkscrews.
Find and take shortcuts to keep up with the computer-controlled drivers. Perform as many stunts as possible off every jump to earn turbo boosts.
Use up the turbo boosts constantly.
Get a feel for each car, because each handles differently. An off-road vehicle will ride differently than a sleek car with jet motors.
When performing stunts, remember to land cleanly--crashes don't earn you turbo boosts.
