What Is the Mysterious Signal in Fallout 4?
How to Find the Signal
The Mysterious Signal in Fallout 4 can be picked up on your Pip-Boy radio (frequency 98.7 FM) as you explore the Commonwealth. Unlike typical radio stations, it broadcasts:
- Distorted, robotic voices
- Garbled distress messages
- Unsettling background static
Transcript of the Broadcast
Though hard to decipher, the signal appears to repeat phrases like:
- “Help us…”
- “They’re coming…”
- “No escape…”
- “Signal lost…”
These messages suggest a desperate plea for help, but from whom—or what?
Tracking the Signal: Where Does It Lead?
Step-by-Step Signal Investigation
- Tune into 98.7 FM – The signal grows stronger in certain areas.
- Follow the Signal Strength – Use your Pip-Boy’s radio reception meter to track its origin.
- Discover the Source – The trail leads to a remote bunker in the Glowing Sea.
The Bunker’s Dark Secret
The signal originates from Federal Surveillance Center K-21B, an abandoned pre-war facility. Inside, you’ll find:
- Decayed corpses in lab coats
- Terminal entries hinting at experiments
- A final, chilling holotype
The logs reveal that scientists were studying psychoactive signals to control behavior—but something went wrong.
Fan Theories: What Does the Signal Mean?
Theory #1: Failed Military Experiment
Many believe the signal was part of a government mind-control project (similar to Fallout 3‘s “Dunwich Building” mystery). The logs suggest the scientists lost control, leading to their demise.
Theory #2: Alien Connection
Some speculate the signal is tied to Mysterious Signal Fallout 4‘s alien Easter eggs, possibly a distress call from Zetan invaders or a captured human experiment.
Theory #3: Ghostly Transmission
Could the signal be a post-war echo of the dead scientists? The Glowing Sea is full of radiation anomalies, making supernatural explanations plausible.
Developer Clues: Did Bethesda Leave Hidden Answers?
Cut Content & Unused Audio
Data miners have uncovered unused voice lines in the game files, including:
- “Subject resistance increasing…”
- “Terminate all test units…”
- This suggests the bunker’s experiments were originally meant to be a bigger quest.
