Shadow of Steel

Shadow of Steel is a Brotherhood of Steel main quest in Fallout 4.

Detailed walkthrough
After observing a huge Brotherhood of Steel airship pass overhead, the Sole Survivor's Pip-Boy radio receives a transmission. Listen to it for further instructions before heading to the Cambridge Police Station and following Paladin Danse to the roof.

After a short Vertibird flight to the Brotherhood of Steel's flagship, the Prydwen, disembark onto the flight deck and speak with Lancer Captain Kells.

The Sole Survivor is ordered to attend an address being given by Elder Maxson. Speak to Maxson after listening to his speech. Regardless of the earlier rank in the Brotherhood, Maxson now bestows the title of Knight on the Sole Survivor and awards them a new suit of power armor, which can be found in bay 3 of the main deck.

Check in with Paladin Danse on the main deck to complete the quest.
