Mission Mode

Mission Mode is a mode in Mario Kart DS in which the player has to do various missions. There are 7 levels, and there are 8 normal missions in each level plus one boss battle. They use all the tracks, but only the first eight characters each in their respective standard karts. The Grand Prix rankings are used (although, for different times).
