Call to Arms

Call to Arms is a Brotherhood of Steel main quest in Fallout 4.

Detailed walkthrough
Paladin Danse asks the Sole Survivor to follow him to ArcJet Systems where he hopes to get his hands on a deep range transmitter to repair the Brotherhood of Steel communications array.

Once the Sole Survivor has agreed to assist Danse, he will order Scribe Haylen and Knight Rhys back into the police station. Follow them into the police station, where Danse offers the option to "resupply yourself." Take all the time required to prepare for the mission, which may include talking to Scribe Haylen or Knight Rhys. Once the Sole Survivor is ready to start the quest proper, they should speak to Danse and tell him that they're ready to head out.

Paladin Danse will either lead the Sole Survivor west to the abandoned ArcJet Systems building or they can just meet up at the building. Choosing the latter option will result in missing the following scripted encounters and their accompanying loot and experience.

As Danse first reaches the river shore road, one will find a pile of ghoul and raider bodies which was not there before, along with two active frag mines. Then, a group of raiders will be found ambushing some traders under the railroad bridge: after the fight is over, the corpses, especially those of the brahmin, usually contain loot (these corpses will despawn after leaving the area, meaning they must be looted after the fight or not at all) Further along, Danse and the Sole Survivor may be attacked by various local dogs and insects before finally reaching the ArcJet building.

Once reaching the building, speak to Danse about the transmitter and automated security. Then provide fire support for Danse while following him through the building. He will express his dismay at discovering the presence of Institute synths.

Head into the lab analysis room. The door to the next area is locked. There will be the option to either hack (Advanced difficulty) into the lab control terminal or use the lab analyst's terminal to receive the lab control terminal password. This will open the door.

After opening the door, continue fighting through the building. The second floor corridor just outside the CEO's office is lined with turrets. Either fight through the hallway with Danse or use the terminal in the server room nearby to disable them. Continue following Danse to the elevator leading down to the ArcJet engine core.

Paladin Danse and the Sole Survivor will need to reach the top of the engine core in ArcJet Systems. This first requires searching for a way to restore power to the access elevator. This is done by hacking the facilities terminal (Novice difficulty).

Either start the auxiliary generators and return to help Paladin Danse with his synth problem or press the Engine Start button on the Engine Core panel and watch the synths fry. After defeating all the synths with either method, check in with Paladin Danse, then take the elevator.

Battle to the control room and secure the Deep Range Transmitter off the corpse of a synth then leave the facility via the control room elevator. Outside, Danse will reward the Sole Survivor with Righteous Authority and offer them the chance to join the Brotherhood. Regardless of whether the Sole Survivor joins or not at this time, Danse will be found back at the Cambridge Police Station, where additional quests can be obtained from him, Haylen and Rhys if the Brotherhood is joined.

Bugs

 * After Paladin Danse notes that there are turrets up ahead, he might turn around and head back in the direction you came, eventually coming to a stop and not moving at all. To get the quest to progress, destroy the turrets, and Danse will resume heading in the direction he is supposed to.
 * When Paladin Danse reaches Arcjet Systems, before entering he may run back to the Police Station. Once there he will stand in front of it and will not talk. However if you continue the quest normally (albeit without danse), he will teleport to you at the end and the quest can be finished as normal.
 * If this quest is not completed before Reunions and the Prydwen shows up, it will trigger a glitch that not all Brotherhood Vertibirds and patrols will spawn correctly.
 * After you finish the quest and head into the service elevator, the elevator door might not open, leaving you stuck in there.
 * This can be fixed with the console command . Note that this may cause excessive lag afterwards, in which case, use the console command.
 * When trying to leave ArcJet through the elevator, you might get a CTD. Reloading a save doesn't help and you are stuck here. To get out, use console command . Once out, enter in the bunker and go to open the elevator doors, just like if you get out of it. Paladin Danse will pop and the quest will continue normally.
 * The terminal found in the room with the Fat Man is mislabeled as an Expert level hack, when in reality it is a Master level.
 * If the Brotherhood has been destroyed, the quest will be impossible to complete, as you will not be able finish the quest by speaking to Danse. This can be fixed with.
 * The majority of the Arcjet Systems interior is supposed to be inaccessible unless the player is currently on this quest and accompanied by Paladin Danse. However, it is possible to accidentally glitch through doors/walls/floors of the public entrance hall into the quest-specific area. Exploring this area can cause the quest to get started and accelerated to a later stage without being properly set up. As a consequence, Paladin Danse and the player's companion can get permanently stuck in the rocket test chamber control room. If this happens, any companion the player recruits from then on will automatically run to Arcjet Systems and stay in the test chamber until they are dismissed.
 * This can be fixed with the console command (or ), which will remove the override-priority AI package from Danse, the current companion, and/or Dogmeat.
