This is the sixth extreme stunt game of the Uphill Rush series. You first will get to pick from four different tracks to race against one main opponent. Not only will you need to win the race but you will also need to outperform him or her by doing some awesome stunts off your inner tube or dirt bike. While you are racing on your dirt bike you will need to tilt left and right to increase and decrease your speed while going up and down slopes. This is definitely another excellent addition to the Uphill Rush games that are all very addicting to play.
