Everyone knows that Mario is always on a mission to save the Princess from the evil Bowser. Well guess what...he"s gonna have to do it again but this time he won"t be running through Mario Land. In Mario Defend Princess you are going to have to fight off and shoot down waves of bad guys who are coming to capture Princess Peach. But the good news is you"ve got your cannon and its shots are deadly. If you aim right you can take out more than one baddie at a time but you will need some good timing to hit all of the fast moving targets. Don"t let them get too close or they will take the Princess.
