How to Complete the Speak of the Devil Quest in Fallout 4

How to Start the Speak of the Devil Quest

The Speak of the Devil Quest starts automatically when you load into the game after updating your game to Next Gen Update. You will see the quest pop-up for Speak of the Devil on the left side when you load in and if you aren’t following any quest at the moment, the quest marker will also be displayed on the map. However, you can also follow the quest through the Quests menu of your Pip-Boy.

Browse the Wattz Electronics Store

Go to the Wattz Consumer Electronics store located in the Commonwealth and head inside the store. Pick up The Black Devil Vol. 1 Holotape and use it to read both entries. After that, pick up Connie’s Note and read it to move on to the next objective.

Investigate the 0MC-810 Relay Tower

Leave the store and continue in the northeast direction to reach the 0MC-810 Relay Tower. The tower will be guarded by a couple of Enclave Remnants so make sure to take them out first. Once you have dealt with the enemies, go to the objective marker to find Richie’s Body. Pick up Richie’s Note from his body and then read the note.

NOTE: You can find the Note in the Miscellaneous section of the Inventory Tab of your Pip-Boy.

Load AM holotape into the 0MC-810 Relay Tower Terminal

After reading Richie’s Note, interact with the terminal beneath the tower and select the Extend Satellites option. Wait for the satellites to rise on the tower and then select the Load AM 010 Holotape option. Doing so will give you the option to transfer the files. Continue to transfer the files and then select either “Stars and Stripes Forever” or “Battle Hymn of the Republic” to complete the transfer.

Investigate the BADTFL Regional Office

Once done at the Relay Tower, open the map to find the objective marker for the BADTFL Regional Office in Charlestown. Make your way to the BADTFL Regional Office location and go inside it. The place will be crawling with Raiders so feel free to take them out. Make your way to the interrogation room to find Connie’s Body with an FM 52.7 Music Catalogue holotape beside it. Pick up the holotape and use it on your Pip-Boy.

Find a password or hack the holotape

The holotape will require a password to access it. There are three possible options through which you can hack open the holotape.

  1. If you have the Hacker 1+ perk, you will see a list of possible passwords for the holotape. Find and select the “El Diablo Viene” password to hack the holotape.
  2. If you have the Hacker 3+ perk, you will automatically hack into the holotape.
  3. To find the password, look at Connie’s confession note to find a hint, “CHECK THE WALL”. Look at the wall behind Connie and you will find a cigarette paper on top of a pack of cigarettes inside a hole.

The Cigarette paper will reveal the password for the holotape allowing you to access it.

Load the FM holotape in the OSC-527 Relay Tower terminal

Leave the BADTFL Regional Office building and follow the objective marker to reach another relay tower. Once you are at the OSC-527 Relay Tower, access its terminal and extend the satellites. Wait for the satellites to rise and then load the FM 52.7 Holotape.

Continue to transfer the files of “America the Beautiful” to the relay tower. Once done, open the FM holotape and go to the Transcriptions to open the Raw audio transcriptions #0130 to get more information.

Investigate the Boston Police Rationing Site mentioned in the transcription

Follow the objective marker to reach the Boston Police Rationing Site and as you reach the location, you will see that the main door will be barred. To get inside the building, you need to jump on the train to make your way to the building and then go around the containers to reach the other side of the building.

Here, you will find an opening to get inside the building and go to the Utility Tunnel. Simply go along the tunnel to reach a room at the end. Interact with the radio beside the locked door to open it and the quest will be concluded. The room contains a powerful Power Armor named X-02 and it will be all yours for the taking.


Completing the Speak of the Devil quest will give the following rewards to the players.

  • 449 XP
  • X-02 Power Armor
