Play Mario the Commando in this game called Super Mario World Hardcore. This is a killing game wherein players are allowed to walk back in each level to find more targets. Move Mario by pressing the left and right arrow keys. Make him jump by pressing the X or the up arrow key. Shoot at the enemies by pressing C. Change your weapons by pressing 1, 2, 3, or 4. Super Mario World Hardcore is a parody of the normally quiet and straightforward Mario games. Here, players are required to use guns and ammunitions to eliminate enemies. You can say that this one gives you a good feel of a Super Mario killing spree on a mushroom killing field. Actually, Mario is almost invincible in this game. You don’t even have to fire to kill the enemies. They simply die when they touch your gun.
