Super Mario Kart Xtreme is like a crazy death match. You have to go fast. Like really FAST! The faster you go the better your chances are of destroying the plethora of enemies walking the streets. If you drive like an old lady, you will take damage and spin out instead. Speaking of enemies, you will notice some famous and nostalgic ones in this game. The only thing you can't smash are the Thwomps (stone blocks).
