The Mauler

The Mauler is a melee weapon available in the Fallout 3 add-on The Pitt. It is a unique Auto Axe that deals much more damage than the original. It can be obtained from Everett during the quest Unsafe Working Conditions once 80 Steel Ingots have been handed in.

Statistics
It has a larger damage/hit and damage/second ratio compared to the standard Auto Axe (45 compared to 35) and uses less AP (50 compared to 65).

Bugs

 * Its animation doesn't loop correctly. If you continuously grind the air, you will notice the weapon "twitching" after several seconds, like the animation starting over again and again.
 * When using it in FPS mode it may disappear mid-animation, bringing up the Pip-Boy immediately afterwards you will notice that your Pip-Boy has disappeared too (but not the screen). Changing to a different weapon quickly clears this bug. (confirmed PS3)
 * Sometimes when you first equip and then use The Mauler, The Man Opener, or the Auto Axe, the spinning blades will disappear. Simply equip another weapon via Pip-Boy, and re equip the weapon and the blades should now remain visible.

Behind the scenes

 * Everett says that this is one of his favorite weapons, and that he used it to chop up ghouls and trogs from The Pitt to Monroeville, PA. The mention of ghouls is likely a reference to the fact that the Monroeville Mall was the location where the original Dawn of the Dead was filmed and in Night of the Living Dead the police and news casters call the zombies "ghouls". Also, "zombies" is a common derogatory name for ghouls.
 * The Pittsburgh Maulers were a team in the short-lived United States Football League.
