Shipbreaker (quest)

Shipbreaker is a side quest $$

Detailed walkthrough
While exploring the Island, the Sole Survivor may randomly pick up the Shipbreaker's radio frequency, immediately starting the quest. Provided settlements have been built on the Island and settlers were recruited, any of them may approach the player character to tell them about Shipbreaker, starting the quest as well. The location of Shipbreaker, a unique fog crawler, will depend on where the player character picks up Shipbreaker's signal. Known locations for Shipbreaker include north of Briney's Bait and Tackle, just west of the Glowing Grove, halfway between Atom's Spring and the Nucleus, and just outside of the Oceanarium. Once the fight is over, the player character is prompted to speak to Old Longfellow. He will talk about how he has been searching for Shipbreaker for years. Tell him that Shipbreaker is dead, and the quest will complete with the player character earning Skipper's Last Stand, a unique harpoon gun that Old Longfellow was saving to deal the final blow on Shipbreaker with.
