Complete Hull Breach 3/Blood Tide (Part 2) in fallout 4. Get the Defender's Harpoon Gun by turning in 3 Mirelurk Carapaces to The Mariner.
Walkthrough
- 1From Echo Lake Lumber, head west around the hedge to reach the road bordering Zephyr Ridge Camp. Follow this road south-west, sticking to the paved path and ignoring side areas for now.
- 2The road will turn south, leading to an ambush by Trappers. Defeat them and continue south until you see a wind turbine to the west, also occupied by Trappers. Be cautious of the Trapper at the top of the tower, as they wield a Fat Man and have a superior vantage point; sniper rifles are recommended.
- 3Clear out Zephyr Ridge Camp. Loot the shack to the south for an Ammo Box. Find a Weapons Workbench to the north, near an Explosives Box. Head upstairs to find a Steamer Trunk and a Terminal that can shut off spotlights.
- 4Travel south-west from Zephyr Ridge Camp into the wilderness to find Rock Point Camp. This area contains more Trappers, a ruined house with a truck in a rib cage, a boat house to the west (containing an Ammo Box), and walkways leading to a stone island and a sunken ship.
- 5Advance along the walkways, eliminating Trappers. Loot a First Aid Box west of the boat house, an Ammo Box and a Wooden Crate on the way to the sunken ship, a Steamer Trunk on a small rowboat south of the sunken ship, and a second Ammo Box on a rocky outcrop at the end of the southern walkway.
- 6Swim north-west from the sunken ship to reach an island. Kill the Gulpers present and search the northern end of the island for a Novice Safe.
- 7Return to the boat house, go upstairs to the east, and follow a dirt road east then south-east. Pass a house to the west and head south behind it to find Haddock Cove, populated by Mirelurks.
- 8Defeat the Mirelurks in the area. Loot the north-eastern-most shack (east of the one with a capsized boat beneath it) to find the body of Bray Husky. Loot him and take the “Holotape” from a nearby table.
- 9Follow a walkway south from Bray’s shack to another shack containing the body of Braun under some stairs. Upstairs, find a Tool Chest with a First Aid Box on top, and the corpse of Luke.
- 10Continue west across a walkway, looting a pair of Wooden Crates. Descend to a lower level to find a Trunk, the “Husky Family Holotape” on a wooden crate, and two Ammo Boxes on a metal shelf.
- 11Follow a walkway west then north to another shack with a Duffle Bag and a Wooden Crate. Further north is the shack with a boat underneath, containing a Tool Chest, loot on metal shelves, a Weapons Workbench, the “Chores List” Holotape, and some ammo.
- 12Head east of Haddock Cove to a partially flooded house. On the top floor, find three notes: “A Vengeful Creature”, “The Children Trapped”, and “A Stranger Arrives” on a table, and another note “A Safer Way” with three Stealth Boys underneath the table.
- 13Travel south-east from Haddock Cove through a swamp filled with Anglers and Gulpers. Follow the road as best you can, looting houses along the way. Find an Advanced Safe in the muck south of the road near a tree marked with glowing Blight.
- 14Continue following the road until you spot a house just south of a yellow shipping crate. On the second floor of this house, find an Advanced Safe near a desk. In a smaller room to the north-west, locate the bodies of two Synth Refugees and a Duffle Bag containing a “Scrawled Journal”. Ascend to the highest level to find an Ammo Box.
- 15Continue following the road until you reach Fringe Cove Docks. Discover the area without getting too close, then proceed east, north-east, and east again past Gulpers and through shallow water until the road splits.
