While playing you are notified via on screen text that a settlement needs your help defending it. On arrival you find it under attack, after a successful defense a settler will thank you and initiate a short conversation.
A controlled settlement can come under attack from one of several different groups: super mutants, feral ghouls, synths, raiders or Gunners. The quest consists in defending the settlement against the invaders. Once all the invaders have been eliminated the player character can report to the settlement leader.
- Nothing seems to prevent these attacks from occurring.
- Failing to provide assistance can result in damaged defense equipment, generators, crops, and/or a loss of settlers.
- On Spectacle Island the settlement can be attacked by a group of mirelurks.
- Being friends with The Institute doesn't prevent synths from attacking settlements.

- pc ps4 xboxone Sometimes the quest objective might mark itself as completed before all enemies are killed.[verified]
- pc ps4 xboxone Sometimes the quest doesn't complete.[verified]
- Search inside and outside of the settlement for enemies that have not been killed and kill them.
- pc Open the console. Target a dead enemy (by clicking on their corpse). Enter the command resurrect, exit console and kill the resurrected enemy. This will help in case the kill-counter is missing a kill.
- pc If on arrival you find your settlers have killed a synth infiltrator you may also find there is no attack incoming. Open the console, and enter the command completeallobjectives WorkshopSynthInfiltrator02. The quest will complete.
- pc ps4 xboxone When defending a settlement against an invasion of synths, the quest may become stuck and uncompletable if the first synth is killed before more can spawn.[verified]
- pc ps4 xboxone After completing one of these quests, some settlers may get stuck in the "thank you" mode, i.e. constantly thanking you when you try to talk to them, locking out all other options such as trading and bartering.[verified]
- This can be fixed by talking to a settler or shop-owner from another settlement.
- pc Also can be fixed by using the console. The bug is triggered when settlers are not correctly removed from the "WorkshopAttackDialogueFaction" faction by the appropriate script. This faction has the editor id 1125FE. To solve it, open the console, select a settler then enter command removefromfaction 1125FE
