The Mauler

The Mauler is a unique AutoAxe given to the Lone Wanderer by Everett during the quest Unsafe Working Conditions once he or she has handed in at least 80 Steel Ingots.

Statistics
It has a larger damage/hit and damage/second ratio compared to the standard AutoAxe (45 compared to 35) and uses less AP (50 compared to 65). This weapon also seems to automatically block when you are attacked by another melee weapon.

History
Everett says that this one of his favorite weapons, and used it to chop up ghouls and trogs from The Pitt to Monroeville. 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.
