The single-player tournament (the main campaign) is a massive undertaking. It's a sweeping tour of every track, and it features varying race types and mutators, meaning there are entire events of several races in a row where you have Boost Madness and are in the Stunt race type, or there will be races with no racer collisions, etc. This means you have to switch up your racing style, and we found that tweaking the parts of our bike or ATV made a difference in certain events. http://naildbiter.com/fYusU
