Chapter 2: Cleaning Up the Berg - Borderlands 2
Travel to the Southern Shelf next. Follow the path to reach the town. Take out the bandits and the bullymongs to clear the area. Once done, wait for Claptrap to touch Sir Hammerlock's electrified gate then head there to meet him. Give him Claptrap's Eye to fix him.
Follow Hammerlock to the Bounty Board so he can turn on the power. Talk to him to turn in this mission and start a new one.
