You’re wandering through the Commonwealth, probably looking for adhesive or a screw, when a weird radio signal pops up on your Pip-Boy. It’s called the "Mysterious Signal," and if you’ve played the Fallout 4 next-gen update, you know exactly what’s coming. Or you think you do.
All Hallows Eve Fallout 4 is one of those quests that feels like a quick Halloween-themed detour but turns into a claustrophobic nightmare faster than you can say "War never changes." It’s basically a love letter to the campy horror vibes of the pre-war era, tucked away in a corner of Boston that most players walk right past.
Honestly, the hardest part isn't the ghouls. It’s the math. People are literally tearing their hair out over a four-digit keypad while a legendary glowing one tries to turn them into a radioactive snack.

How to Actually Start the Quest (Without it Bugging Out)
Look, Bethesda games are... Bethesda games. Sometimes that "Mysterious Signal" just doesn't play. You tune in, and it's dead air. Or the quest marker refuses to show up.
If that happens, don’t panic. You don’t actually need the radio to trigger the event. You just need to find the Harbormaster Hotel. It’s located on the eastern edge of downtown Boston, right near the water and south of the Shamrock Taphouse.
Once you see a bunch of raiders who’ve clearly spent too much time decorating with severed heads, you’re in the right place. Wipe them out, head inside the lobby, and look for the door to the New England Technocrat Society. That’s where the party starts.
The Ambush and the "Technocrat" Nightmare
The moment you step into that auditorium, you'll notice the green mist. It's not just for atmosphere; it’s toxic gas. It’ll chip away at your health while a small army of feral ghouls decides you're the main course.
The star of the show is Mr. Wendt. He’s a legendary glowing ghoul who has a ridiculous amount of health.
Pro Tip: Bring something with high DPS. A Tesla Cannon or a fully upgraded combat shotgun makes this way less of a headache. If you’re low level, stay on the move. The gas makes your vision go wonky, and getting cornered by Mr. Wendt is a quick way to see the "Loading" screen.
After the dust settles, you’re stuck. The doors are locked. You need a password. This is where most players get stuck for twenty minutes.
Breaking Down the All Hallows Eve Password
You'll find a body in the hallway named Lana. She’s got a note. It’s a classic "count the objects" puzzle, but here’s the kicker: people always miss the stuff hiding in the shadows.
There are four numbered rooms. Each room corresponds to a digit in the code.
- Room 1 (Specimen Jars): There are 4 jars. Pretty straightforward.
- Room 2 (Skull Candles): Look closely at the candles on the shelves. There are 3 of them.
- Room 3 (Teddy Bears): These little guys are everywhere. You’ll find 4 teddy bears in total.
- Room 4 (Jack-O'-Lanterns): This is the trap. Most people count four or five. You have to look under the table and behind the couch. There are 6 pumpkins.
Put it all together and the code is 4-3-4-6.
Once you punch that in, the back room opens up. You can finally shut off the AI control system on the terminal and stop the gas from melting your lungs.
The Loot: Is It Actually Worth It?
Short answer? Yes. Especially if you’re into settlement building.
The big prize is the Picket Fences Halloween Special magazine sitting right on the terminal. Picking this up unlocks over 30 new settlement items. We’re talking spooky trees, cauldrons, ghosts, and those iconic spider lights. If you’ve ever wanted your Red Rocket truck stop to look like a haunted attraction, this is the only way to do it without mods.
Then there are the helmets. You get the De-Capitalist Helmet, which is basically a TV head for your Power Armor.
- It’s customizable at a Power Armor station.
- You can change the screen to different faces (including a "Yes Man" style face).
- It actually has decent stats for a cosmetic-heavy item.
Common Glitches to Watch For
Even in 2026, the next-gen update has its quirks. A common one is the De-Capitalist Helmet expressions not showing up when you try to modify them. If this happens, try a full game restart. Sometimes the scripts just need a second to breathe.
Another annoying issue is the quest not "completing" in your log after you disable the AI. Make sure you read the terminal entries and wait for the "Quest Complete" notification before fast-traveling out of there. One stray robot usually spawns when you try to leave—kill it, or the game might think you're still in combat.
Actionable Steps for Your Playthrough
If you’re planning to tackle this tonight, here is the most efficient way to handle it:
- Check your level: Don't go in under Level 10. The ghoul swarm in that tight auditorium is no joke.
- Power Armor is your friend: Not just for the defense, but for the radiation resistance against Mr. Wendt.
- Don't overthink the puzzle: If you don't want to count pumpkins in the dark, just remember 4346.
- Scavenge the "NETS" area: There is a lot of high-value junk (and some rare liquor) in the back rooms that people often overlook in their rush to get out.
Make sure to grab the "Felt Hat" sitting near the terminal too. It’s not a legendary piece of gear, but it’s a unique collectible you won't find anywhere else in the Commonwealth.
