Time Attack is what it says it is, the basic 'set your best time and try to better it' mode. Boost Madness, I have to say, was my favorite, where all players have unlimited amounts of boost during the entire race. Talk about crazy, as if the races aren't fast and furious enough as it is; now you have never-ending rockets strapped to you. The terrain starts to become a blur, in the meantime, you're still trying to navigate to the track without getting Nail'd. http://naildbiter.com/1OEvv
