This Gunzerker has a challenge that is repeatable due to an exploit. (Do damage with reloads with Tediore Weapons) > All you have to do is use the level 3 pistols Tediore Pistol on the Zerker and throw it at the bul-loader/Robot enemy right at the beginning of hero's pass. Or anywhere else in the game. > You can move behind a barricade and lob the weapons over for 166 Bad ass levels per weapon thrown without being hit. > Make sure to have the ammo regen on so you can throw it infinite times. > The Challenge is already completed but do to and exploit it will unlock every time you deal damage with the tediore weapons on a robot. Use the top notch Handgun. & Play-through 2 so you don't kill him quickly Could easily apply this with a turbo controller for easy farming. The loader doesn't like to move when your behind the Barricade and you could go afk. I am the one who originally created this save and I am to credit.
