Federal Surveillance Center K-21B

Federal Surveillance Center K-21B, located underneath an abandoned shack, is a location in the Commonwealth in 2287.
==Background==
Federal Surveillance Center K-21B was an underground surveillance facility used by the government before the Great War; it is now north of the impact crater in the Glowing Sea. The bunker was intended to serve as an outpost for government surveillance workers, who were to continue their work after the bombs fell. However, few workers made it to the facility; a holotape recorded by an employee named Jeff Buzensky details the death of his coworker Bill Stevens, who was only a few steps away from the trap door entrance when the bomb struck after leaving to retrieve some personal effects from his vehicle. The bunker was not stocked with enough food due to budget cuts, and its inhabitants eventually died of starvation.Fallout 4 Vault Dweller's Survival Guide Collector's Edition p. 360: "[5.18] ABANDONED SHACKWarning! Extreme radiation danger! An unassuming shack has a federal survival installation (codenamed K-21B) hidden beneath it. Enter the shack and open the trapdoor (Novice) or use the key in Bill the skeleton’s suitcase."(Fallout 4 Vault Dweller's Survival Guide Map)
==Layout==
An armor workbench and a few nuclear waste barrels are on the porch of the shack. The shack itself contains a Novice-locked trap door in the floor next to a skeleton and Bill's suitcase. Through the trap door is the bunker comprising the three-level underground facility, with an open shaft passing through the middle. Up to three synths inhabit the interior, one of which is a synth leader.
On the lowest level is a power armor station under the stairs, as well as a trunk and an Advanced-locked safe to either side of the Novice-locked mainframe terminal. The terminal can be used to reboot the system and reactivate the elevator across the room leading back to the surface south of the shack. However, activating the elevator will also enable two hostile Protectrons, which cannot actually be disabled using the terminal.
==Notable loot==
* Evacuation plan note and Installation K-21B key - In Bill's suitcase in the abandoned shack. The key unlocks the nearby trap door.
* Employee 011985TP personal log holotape - On the desk near the entrance on the upper level.
* Stealth Boy - Behind a box of file folders on a desk in the eastern corner room on the middle level, in the same room as the Eat-o-tronic.
* Two Vault-Tec lunchboxes - One is on top of the main control structure to the right of the mainframe terminal on the lowest level accessible by jumping down from the middle level, and one is on a small cart behind the power armor station on the lowest level.
* U.S. Covert Operations Manual issue #4 - To the left of the mainframe terminal on the lowest level.
* Partial set of power armor with fusion core - In the power armor station on the lowest level.
* Mini nuke - Near the power armor station on the lowest level.
==Notes==
* The interior of the bunker does not respawn.
* The map marker changes from "Abandoned Shack" to "Federal Surveillance Center K-21B" after using the elevator to leave the bunker.
* If the player character is friendly with the Institute upon first entering the bunker, the synths will be allied and will not attack the player character. The synths will speak using the same dialogue as those found in the Institute and elsewhere in the Commonwealth.
* There are only three actual "radios" in the bunker, with one on a desk in the northern room on the middle level and two on desks on the lowest level. The other radio objects in the facility are labeled "surveillance device," and emit only static.
===Companion comments===
* When at this location, companions make comments, which are activated at the gantry overlook.

==Behind the scenes==
The map that is on the wall of this facility is the same map that is shown on the globe objects in the rest of the Commonwealth; this map has two errors. First, the locations of the Soviet Union (such as Ukraine, Kazakhstan, etc) are shown to be independent, as is Canada separate from the United States. The second error is that the Black Sea, Baltic Sea, Caspian Sea, Great Lakes, Mediterranean Sea, Persian Gulf, Red Sea, and the northern half of the Gulf of California are colored as if they were landmasses, and not bodies of water.
