Mario and Sonic are two of the most popular heroes. If you don't heard of them before then you are missing a lot of things when you were a kid. Sonic is hedgehog and is considered one of the fastest in the world while Mario saves the Mushroom Kingdom from King Kuppa. Anyway, that is in the past and now they are just regular guys with nothing else to do. They are really bored, so they thought of having a race, but since Sonic is the fastest guy then it won't be a competition, so they decided that it would be a truck race.
You can choose which character would you want to be. Start the engine upon hearing of the word "Go". Drive your truck as fast as you and don't hold back since the other guy would do the same. Try to balance your truck at all time at that would not only damage your truck, but would also slow you down. When the life bar is down to zero then the game is over. Beat the other guy, so you can advance to the next level. The game gets harder and harder as you make some progress.
