MX Unleashed Hint: Tough Demo Track Race
Let the game sit on the main menu for a little while until the demo comes up. Press a button on the control to play that demo track. The A.I. will be tougher than usual, just for that race.
MX Unleashed Hint: horizon bounce-back
In freestyle mode keep going straight in any direction until you go up a big hill. Then go over it and you will see a flat horizon. You then drive straight into it and the force will bounce you back very far.
