Meet Sir Hammerlock. You've found Claptrap's eye, but he still needs someone to plug it into the socket. That someone happens to be one Sir Hammerlock who currently resides in the town of Liar's Berg. Claptrap wants you to head there now.
When you get there though, Sir Hammerlock refuses to help you until you clear the town of Captain Flynt's bandits.
Claptrap can finally see! Now it's time to get to Sanctuary. Unfortunately, one man stands between you and the last free city on Pandora. His name: Captain Flynt.
