You're wandering through the Commonwealth, minding your own business, when a random quest notification pings on your Pip-Boy. Speak of the Devil. It sounds ominous, almost like something out of a horror mod. But if you’ve been playing the 2024 next-gen update (or you're a long-time Creation Club veteran), you know this is actually one of the coolest pieces of Enclave-centric content Bethesda ever baked into the game.
Honestly? Most players treat it like a simple fetch quest for some shiny armor. They're wrong.
Sure, the prize at the end is a set of X-02 Power Armor, which is basically a walking tank with a meaner silhouette than the standard T-60. But the story—the mystery of the "Black Devil"—is where the real meat is. It’s a detective story wrapped in a radio broadcast, and if you aren't paying attention, you'll miss the subtle tragedy of the people who died trying to summon a hero who wasn't coming.
How to actually start Speak of the Devil
You don't need to go hunting for a specific NPC. If you've updated your game recently, the quest usually just pops up once you leave Vault 111. If it didn't, don't panic. Just head over to Wattz Consumer Electronics. It's right in the middle of the map, north of the ruins of Boston.
Inside the store, you'll find a holotape titled The Black Devil, Vol. 1 and a note from a woman named Connie.
Read them.
Listen to them.
The lore here is fascinating: it's about a legendary figure who supposedly appears whenever a specific patriotic radio station is played. Think of it like a post-apocalyptic Batman, but with more fusion cores and less emotional stability.

The Radio Tower Chase
This quest is basically a road trip through the northern Commonwealth. You’re going to be bouncing between relay towers, and yeah, it gets a bit repetitive if you’re just rushing for the loot. But keep your eyes peeled.
Relay Tower 0MC-810
First stop is northeast of Wattz. You’ll find some Enclave Remnants here. They aren't the massive army you see in Echoes of the Past, but they’re still annoying. Loot a guy named Richie. You’ll find a music catalog holotape.
Use the terminal. Extend the satellites.
Upload the "Stars and Stripes Forever" file.
This isn't just flavor text; you're literally rebuilding a signal that the Enclave is trying to suppress. It’s a cool bit of world-building that makes the Commonwealth feel like it has actual layers of history.
The BADTFL Regional Office
Next, you're heading back toward the city to the BADTFL office. It’s usually crawling with Raiders, so bring something that goes boom. In the interrogation room, you’ll find Connie. Well, you'll find what's left of her.
There's an encrypted holotape on her desk.

Pro-tip: Don't waste your time trying to hack it if your skill is low. Look at the wall behind her. There’s a tiny piece of cigarette paper tucked into a hole. The password is "El Diablo Viene." ### Relay Tower OSC-527
Down south now. Near Diamond City. Same drill: extend satellites, upload "America the Beautiful." You’ll probably run into some high-level Mole Rats or a Brood Mother here. They're gross. Kill them.
The Boston Police Rationing Site: Don't Get Blown Up
The final marker leads you to the Boston Police Rationing Site. This place is a nightmare to navigate if you don't know the trick. The front door is barred.
How to get in:
- Look for the shipping containers outside.
- Use them to jump onto the roof.
- Drop through the hole in the ceiling.
Once you're inside, you’re looking for a utility tunnel. Watch out for the gas leaks. One stray bullet and the whole hallway turns into a furnace. I’ve seen players lose twenty minutes of progress here because they forgot to save before the floor turned into lava.
The Choice: Radio or Upgrades?
At the end of the tunnel, you’ll find the Black Devil's lair. There it is—the X-02 Power Armor. It looks incredible. But the quest isn't over. You have to use the terminal behind the armor, and this is where most people get tripped up by the "moral" choice.
You have two options:
✨ Don't miss: Playing A Link to the Past Switch: Why It Still Hits Different Today
- Restore the Enclave Signal: This keeps the radio station active permanently. It’s great for atmosphere, but it also means you’ll get hit by random Enclave ambushes more often as you travel.
- Short-circuit the Radio: This shuts the station down for good. In exchange, you get the Devil’s Inferno mod for your X-02 chest piece. This mod adds a Tesla-style aura that deals energy damage to enemies who get too close.
Honestly? Take the mod. The radio station is cool for about five minutes, but that energy aura is a lifesaver when you're being swarmed by Ghouls in the Glowing Sea.
Why the X-02 is worth the hassle
The X-02 isn't just for show. When fully upgraded to Mark VI, it rivals the X-01 in pure defense and energy resistance. Plus, it has unique "Enclave" paint jobs that give you a boost to Charisma or Agility depending on the configuration.
It’s the best "evil-looking" armor in the game. Period.
Actionable Insights for Your Playthrough
If you're planning to tackle this tonight, keep these three things in mind:
- Level 30 is the sweet spot. You can do this earlier, but the Enclave Remnants at the towers will chew through a low-level character in seconds.
- Bring a Hazmat Suit. The tunnels under the Rationing Site have some nasty radiation pockets.
- Check the safe. There is a safe in the final room that only opens if you use the terminal after making your choice. It contains extra Enclave lore and some high-tier loot.
This quest is a rare moment where Fallout 4 feels like a mystery game. Don't just follow the markers. Read the notes. The story of the Black Devil is a tragic reminder that in the wasteland, sometimes the heroes we invent are the only things keeping us going.
Now go get that armor. The Commonwealth isn't going to save itself.
Next Steps for the Sole Survivor
- Head to Wattz Consumer Electronics to grab the first holotape.
- Make sure you have at least Hacker Rank 1 or a spare grenade to bypass the entry at the Rationing Site.
- Clear out your inventory; that X-02 frame and its parts weigh a ton.
