Ultimate Dirt Bike USA sums it all up pretty well in the name really... you will be trying to ride across 40 fun filled levels as fast as you can on a dirt bike across various different locations around the USA!
Each level will have different obstacles and ramps throughout them which you must try to get over without falling off your bike or you will need to restart the level.
The key to getting a higher score is finishing each level as fast as you possibly can as taking longer will deduct points from your final score. Look out for the red nitro boost icons as they give you a short burst of speed to help.
