A missile launcher and a flamer can be found in an armory inside the east corner of the Castle's wall, and may come in handy for defeating the queen. It will make her way through the southwest breach and into the Castle courtyard and begin attacking everything in sight.

When enough of the eggs are destroyed, the entire fort will shake, and a mirelurk queen will emerge from the lagoon - the 'sea monster' that destroyed the Castle in the past. As they clear them out, more eggs will hatch and more mirelurks will emerge. He will tell any remaining Minutemen to remain in the courtyard and take care of the eggs there while he and the Sole Survivor clear the walls.įrom here the Sole Survivor must find the marked mirelurk nests in and around the Castle's walls and destroy all of the eggs. Once the courtyard is clear, Preston will point out the mirelurk nests that are all over the Castle, stating that they need to be taken care of to keep the mirelurks from coming back. The Sole Survivor will need to help the Minutemen eliminate the mirelurks to proceed. Some of the mirelurk eggs may also hatch, releasing mirelurk hatchlings to be defeated. As soon as someone enters the courtyard, mirelurks will begin emerging from the ground and attacking. Once the plan of attack has been decided, the Minutemen will move into position. 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.

As the Sole Survivor approaches, Preston will talk a little about the fort before asking them to decide on a strike plan. Once the Sole Survivor is ready for the attack, they can answer affirmatively to continue with the quest (Preston will wait for them to come back and call the attack otherwise).Īt this point, the Sole Survivor must head to the Castle and meet Preston, who will be waiting in a ruined house with a strike team of three Minutemen. Preston will then ask the Sole Survivor if he should assemble a strike force at the Castle. The next time Preston is talked to, he will bring up the idea of retaking the Castle, suggesting that the radio transmitter there would help with communicating with the growing number of allied settlements. Once the Sole Survivor has recruited at least four settlements to the Minutemen cause, this quest can begin.
