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.
Easter Egg: End Of The World
In freestyle mode in MX Unleashed, drive in any direction for a while. You should come to a big hill. Search around the base of the hill and you should find a sign. Angle the camera so that you can read the sign. The sign should say: End of the World, 500 Feet.
