There are five hidden Ninja difficulty tracks in the game. To unlock each of the secret tracks, complete an Extreme difficulty track with zero faults. Then at the end of the Extreme difficulty track, bail out just before driving across the completion marker. If you can successfully shoot the driver into the cave, hole, or object past the marker, you will start back at the beginning of the track on the Ninja difficulty. Each Ninja track is an extremely difficult variation on the Extreme track. Ninja tracks were originally created in the Trials: Evolution editor by the fan community. Only the best players can complete these tracks, which often require unique or unintended maneuvers to complete.
