This quest can be started randomly when speaking to Preston Garvey or listening to Radio Freedom, who tells you that a settlement needs help defending its artillery piece(s). On arrival, one of the settlers will tell you the Brotherhood of Steel has been snooping around, and they believe they mean to destroy the artillery.
A controlled settlement is under attack by the Brotherhood of Steel, who want to destroy the artillery piece(s). The quest consists of defending the artillery from the Brotherhood invaders. Once all the invaders have been eliminated, the player character can report to Preston Garvey to complete the quest.
- This is essentially the same as Defend the Settlement, but with the Brotherhood of Steel as antagonists and a specific objective to defend the artillery piece rather than the settlement as a whole. This will not stop the Brotherhood soldiers from firing on the settlers, however.
- It seems you get this quest for siding against the Brotherhood, regardless of which faction you choose to do so with.[verification overdue]
- Failing to provide assistance can result in a loss of settlers and/or damaged defense equipment.
