Spectacle Island is a location in the Commonwealth in Fallout 4.


The story behind the island is quite different from many other settlements. The original settlers on the island had constructed a sonar pulse beacon that released a high pitched sonic pulse that was capable of repulsing or killing mirelurks.

The beacon is represented by a structure similar to a siren or radio antennas connected by a long wire to a sunken ship. The ship's generator room is still operational and provides power for the beacon. The appearance of raiders on the island suggests the settlers were unprepared and were killed, the raiders disabling the pulse beacon, looting the area and leaving, allowing the mirelurks to return.

A beached barge on the northeastern portion of the island has a large shipment of Vault-Tec crates within it. It is unknown if these were being shipped to work on one of the incomplete vaults of the Commonwealth such as Vault 88, Vault 114 or Vault 118, or if these supplies were to be used in the construction of a new vault.

Obtain as settlement guideEdit

To unlock the island for use as a settlement, the Sole Survivor must go to the sunken boat to the south and flip the switch on the circuit breaker. This will cause the screen to shake and a mirelurk queen and several hunters will emerge, as well as potentially a legendary mirelurk deep king.

To finish the unlocking process, one must go back and flip the circuit breaker on the radio tower. After a few seconds, this will send out a pulse which will drive all remaining mirelurks to the shores of the island. It is not necessary to kill the queen, as she is affected by this pulse as well. The workshop will then unlock, and one will be able to build at any point on the island.


The island has several buildings scattered across it (mostly shacks and ruined houses). The north side of the island contains several crafting stations in a small shed across from a destroyed house. The main workshop, along with a radio tower, is located in the center of the island. To the south is a destroyed boat containing the Luck bobblehead as well as a large power generator that connects to the radio tower through a series of pylons. Mirelurks populate the shores, as does the wreckage of several boats.

Notable lootEdit

  • Fat Man in the half sunken green tugboat on the southern tip of the island.
  • Luck bobblehead on the same half sunken tugboat to the south, sitting in a locker.
  • Mini nuke on the first floor of the destroyed house, sticking out of some debris on the floor.
  • Signal checklist in a small shack in the middle southeast of the island. This describes the instructions regarding the island's most unique feature: a sonic pulse beacon that repulses mirelurks.
  • Two Nuka Cola Quantums in a broken fridge in an underwater, wrecked house (notable for a skeleton in a wheelchair facing a modern TV and radio) just off the southwest coast. From the derelict hut where Randy is found, head west towards Warwick homestead and dive down 10-15 meters out to sea. Unfortunately these are often glitched under soil within the fridge. The water physics can make them roll out onto the wooden floor when approaching however, so check it occasionally and you may be able to reach one or both.


  • Just after the outhouse near the rocks/shore there is a hub flower plant. While looking in build mode it says it produces 0.5 food, yet it is unassignable.
  • Setting up and turning on a recruitment beacon on the island will work despite the surrounding water; the settlers will only appear if the player character fast travels off the island and then returns. However, if the settler nearby happens to be a ghoul, they may appear without the need for fast traveling.
  • Randy's body is found on the south end of the island.
  • There are multiple settler bodies lying around the island. The mirelurks on and around the island suggest what happened to the previous inhabitants.
  • There is an unmarked cluster of boats and debris moored to a concrete pillar with a shack on top of them with 2 sleeping bags and some crops to the northwest of Spectacle island; it's about halfway in between Spectacle Island and The Castle.
  • There is another location of the sort mentioned above about one map square due south of the island. Built around a tall brickwork pillar, it appears to be a small shanty for a population of three, judging by the number of sleeping bags. It features a compact greenhouse of sorts with a wild mutfruit plant inside a blue freight container, a radio tuned to Diamond City Radio and some packs of dirty water, but no loot of note.
  • Visible due north of the island is a barge with a hut and a doghouse on it, alongside a wooden loot crate and locker for loot.
  • There's a barge that ran aground on the eastern side of the island that has multiple safes inside it. 3 are locked each in increasing difficulty: Novice, Advanced, Expert. A fourth safe can also be found behind the barge directly below where the main 3 safes are found. This also has an Advanced lock. However, lockpicking these safes can be easily avoided by unlocking the workshop and then scrapping the safes.
  • Spectacle Island possesses the largest build area of any other settlement in the game. However, due to the game's settlement build limit and hilly, rocky terrain, the area requires extensive work before it becomes a viable build space. Most of the area's pre-existing structures are cluttered or too badly damaged to use properly and require extensive reconstruction before use. The island also features the second largest height map, meaning players can comfortably build structures of up to 10 stories high if constructed on the beach, and up to 6 stories high when constructed on the highest point on the island.
  • The generator on the ship, once activated, provides 20 units of power for free. The circuit breaker box itself can be picked up during build mode, it can be placed awkwardly halfway through the ground anywhere around the island, but cannot be attached to walls and cannot be placed back where it started if placed somewhere else.
  • When starting this settlement, the size limit is almost halfway. By spending some time on scrapping everything possible, one might find that there's still more items to be scrapped but can't find them. There are many items hidden beneath the ocean, and in order to get to them one has to dive around the wreckage of the barge and the boats to find barrels, junk and crates. There's 2 submerged shipping containers near the barge with many crates and barrels in them. Alternatively, set a supply line from a main settlement and use the weapon settlement size exploit for an infinite size limit.
  • Regardless of where the player character decides to build their settlement on the island, actually finding the resident settlers in order to assign them to work other than growing crops often turns into a chore, simply because they tend to wander around the whole island. Building a bell is an easy way to summon all your settlers to the one place.
  • Since the indigenous mirelurks regularly respawn in sizable numbers, consider equipping your settlers with above-average armor and weapons. However, most of the mirelurks will not respawn if the island's unique signal tower is left on.
  • The beached barge is a good source of wood and steel as there are several open sea containers with wood or metal crates.
  • Firing a flare here will still summon Minutemen.
  • Settler spawnpoint is typically near the radio shack or on one of the hills near it.
  • There is a skeleton with a briefcase hidden in one of the sand dunes.
  • At least two mirelurk kings will spawn here.
  • Diving into the waters in the southwest coast of the island reveals an underwater scene where a submerged ruined house is half buried into the seafloor. Inside this house exhibits several items like a television, a half buried fridge, a side table with a surprisingly fully functioning radio on it, a lampshad, and a skeleton sitting on a wheelchair. A Nuka-Cola Quantum can be obtained under the detached fridge door.


Spectacle Island only appears in Fallout 4.

Behind the scenesEdit

  • Spectacle Island is a real island in Boston Harbor. For most of the 20th century, it was a garbage dump used by the inhabitants of Boston. During the construction of the civil engineering mega project known as The Big Dig, the island's garbage dump was capped off with dirt from tunnel construction and the island transformed into a park. It is now a part of the Boston Harbor Islands National Recreation Area and features a marina, life-guarded swimming beach, visitor center, snack bar, walking trails, etc. Spectacle Island is staffed by park rangers and staff year-round by the Massachusetts Department of Conservation and Recreation.
    • Incidentally "The Big Dig" is also the name of a quest which incorporates elements similar to the real project.
  • It is possible that the crashed/beached barge is a reference to sci-fi author Neal Stephenson's "eco-thriller" "Zodiac" - a barge crashes on Spectacle Island during the narrative of that book.


  • xboxoneIcon xboxone pcIcon pc Even after turning the power generator on the circuit breaker still signifies that the power switch is off even though the tower pylons are lighting up and showing powered on. Occurs when all mirelurks are not killed that correspond with the event of turning on the generator.[verification overdue]
  • ps4Icon ps4 pcIcon pc If one activates the generator before finding the metal shack the game sometimes won't let the player flip the second breaker.facts. On PC to solve that issue open command, target the workbench and type CallFunction SetOwnedByPlayer 1. Then flip the switch one or two times to be in the upper position (again). Now you should be able to open the build menu, but maybe cannot store things to the workbench. To solve that fast travel to another location and back and it should work fine.[verified]
  • xboxoneIcon xboxone ps4Icon ps4 pcIcon pc If one places a structure that affects settlement stats (such as a turret, bed, or a water purifier) on one side of the island and moves to the other side, the stats given may go away, even if it is fully operational. This can affect the happiness of the settlement in a negative way and can be fixed if you move back to the side with the structure, but this is a very temporary fix, as the bug may repeat itself.[verified]
