A mario flash game where you shoot koopas, mainly with a sniper rifle. I admit, it kept me playing till I died. It also gains extra violence points for taking a peaceful game franchise (mario) and adding in guns and blood. Not that I'm ever going to play it again, mind you. I give it 5/10 as it is still very decent for a fan-made flash game.
