In Fallout 76, the Brotherhood Emergency Transponder plays a crucial role in the quest "Belly of the Beast", which is part of the Brotherhood of Steel storyline. This article will guide you through how to use the transponder effectively to complete the quest.
Quest Overview: Belly of the Beast
"Belly of the Beast" becomes available after completing "Recruitment Blues" at Fort Defiance. The quest involves locating Taggerdy using the Brotherhood Emergency Transponder Radio. Here's a step-by-step guide on how to proceed:
Activate the Transponder Radio:
After completing "Recruitment Blues", exit Fort Defiance and head northeast.
Turn on the Brotherhood Emergency Transponder Radio on your Pip-Boy. This will display a signal strength gauge on your HUD.
Locate the Transponders:
Use the signal strength gauge to find the first transponder. It is typically located on a metal bridge or walkway west of Watoga.
The second transponder is near a crashed Vertibot in Watoga.
The third transponder is at Survey Camp Alpha, an old Brotherhood of Steel outpost.
The fourth transponder is at Drop Site V9, on the roof of a structure.
Sync with Each Transponder:
Approach each transponder and sync with it. This will reset the signal strength gauge and guide you to the next location.
Navigate to the Glassed Cavern:
After syncing with the fourth transponder, head east towards the Glassed Cavern. This area is dangerous, so ensure you are well-prepared.
Confront the Scorchbeast:
Inside the Glassed Cavern, you will encounter a Scorchbeast and its minions. Defeat them to reach the final transponder next to Taggerdy's remains.
Complete the Quest:
Search Taggerdy's remains for her ID and return to Fort Defiance.
Use her terminal to learn more about the Scorched and complete the quest.
