Hints

Mercury City Meltdown (bug/shortcut):
About halfway through the course there will be a hard banked left turn. Straight ahead of you, over the banked wall, is a parking garage and a building to the right of the garage. You can slip inbetween the garage and the building to come to a cliff. Jump off the cliff for about a twenty to thirty second free-fall (you can do about 60,000 points worth of tricks, but you will not get credit for them). You will then be taken back to the track and placed right before the end of the track. You will beat all competitors and default records by over a minute everytime.

Super Shortcut:
In Tokyo Megaplex, turn on Sticky Boards (X, X, Right, Y, Y, Down, B, B, Left, A, A, Up) and you can turbo past the fan to finish in only 1 lap.
