Take your pick of 5 colors for your own truly heavy monster truck.  You are timed on each run through harder and harder obstacle courses as you are presented with hills, boxes, tires, bridges, barrels, logs, cement piping (even some semi-trucks!) etc. to get up and over without crashing.  The faster you go, the higher your score – but beware!  If your reflexes are not quick enough you will crash and burn in true monster truck style!  That’s right, up in smoke you will go as your truck explodes!  So don’t get cocky or you will never make the time you need to reach each check point.  Good luck!
