Detailed walkthroughEdit

Once one has established approximately four settlements, including Sanctuary Hills, for the Minutemen, talk to Preston Garvey. He'll tell the player about the Castle, the former headquarters of the Minutemen, and discuss his desire to retake the building to show that the Minutemen are back. Offer to help, and he'll tell the player to meet him outside the Castle.

The hike to the Castle will take one through South Boston and past a number of both raiders and super mutants in equal measure. Garvey is waiting for the player in a destroyed Sullivan's diner west of the Castle with three other Minutemen.

Talk to Garvey, and he'll discuss the player's options. The three Minutemen will offer various potential plans of attack: a direct assault into the courtyard via the breached northwest wall, a pincer through the breach and the main gate to the south, or setting up a firing line outside the northwest breach and drawing the mirelurks out to their guns. When all's in order, the player can launch the attack.

There are about ten mirelurks of varying strength inside the Castle. Once they're all dead, Garvey and the Minutemen will observe the egg nests laying around; if they're not cleared out the mirelurks will keep coming back. Approaching the egg nests will cause several of them to hatch mirelurk hatchlings.

Upon destroying several of the egg nests, the entire fort will shake, and a mirelurk queen will emerge from the lagoon - the "sea monster" that destroyed the Castle in the past. She'll make her way through the southwest breach and into the Castle courtyard, at which point she'll start killing anything she can reach.

Once the queen is dead, the player will have to clear out the remaining egg nests. After they're all gone Preston will tell the player about Radio Freedom, and task the player with getting it up and running. This requires ten power to function. Once Radio Freedom is powered, the player can talk to Preston again to complete the quest.

  • This quest may trigger as part of The Molecular Level, when the player speaks to Preston about building the signal interceptor; he will bring up taking back the Castle in order to fortify the Minutemen's position if they intend to get involved with the Institute.
  • The current number of Minutemen-aligned settlements (player character-owned with at least one settler) to trigger the quest can be tested on the PC console with show MinutemenOwnedSettlements. As this value is only updated when a Minuteman recruitment or radiant quest is handed in to Preston, the player character may have more settlements that meet the criteria than the system recognizes.
  • Any Minutemen that survive the battle will remain at the Castle after the quest is complete as part of the settlement population. One of the Minutemen is an essential character and cannot die, he will operate the radio once the Castle becomes a settlement. The other two Minutemen are not essential characters and can die during the quest; however, if they are alive, they will help clear out the remaining eggs if not yet cleared.
  • The Castle comes prebuilt with an intricate electrical system and an industrial-grade water purifier. This requires significant power to run but cranks out forty clean water resources, enough for two full-size settlements all on its own. Initial building may be hampered by the sludge and debris left by the mirelurks, but simply traveling away and coming back will clear that out.
  • If one dismisses Preston as a follower after he makes the quest available, the player character will not be able to recruit him again until taking the Castle. When the player character tries to talk to him, he will ask if one is ready to take the Castle and will not offer the option for him to follow the player character.
    • This can be very useful; since Preston is recruitable and will wait at the Castle, one can bring along another companion for extra fire support against the mirelurks.
  • If the player character already cleared the Castle, the quest will still be available, however, the mirelurk fight will be bypassed, and the player character will be asked to power the radio transmitter, or clear out the eggs, if not done already.

Companions reactionsEdit

Behind the scenesEdit

  • This quest's name is a reference to the original name of the location, Fort Independence.
50 Vault-Tec C.E.O.The following is based on unverified behind the scenes information and has not been confirmed by canon sources.
  • The presence of mirelurks at the Castle may be an allusion to the lobsterbacks - a slang term for the Redcoat infantry that the Minutemen fought during the American Revolutionary War. This could also be supported by the presence of a mirelurk queen, symbolizing the British monarch.

  • PCIcon pc Playstation 4Icon ps4 Xbox OneIcon xboxone After defeating the mirelurk queen, the marker to meet in the courtyard will appear at a far distance. The path there is very treacherous as it contains synths, raiders, super mutants, mirelurks and deathclaws on most paths there. To fix this fast travel to a few different places and it will automatically fix itself.[verified]
  • PCIcon pc If one encounters the glitch, where the player is required to clear out the remaining egg nests after killing the mirelurk queen, some of the random loot around the fort will have disappeared permanently. Also, a legendary mirelurk that sometimes spawns in one of the fort's rooms may vanish, too.[verified]
  • PCIcon pc Xbox OneIcon xboxone After defeating the queen and clearing out the Fort, Preston Garvey may sit on the wall doing nothing with no speech options. Preston may also walk all the way back to Sanctuary and will continuously say "We need to focus on taking the Castle back". This may be solved by sitting on the chair and wait for 24 hours.
