Help Father Painbringer bring peace to the undead hordes through the gentle medium of the double-barrel shotgun. To complete each level, you must fill the ghoul harvest meter by destroying the undead any way you can. Each time you get hit by a monster or a bullet, you lose some life. At the end of each world you will face a miniboss. These enemies are a lot tougher than regular undead foes and will test your mettle.
