Keller Family Refuge

 refers to an unmarked quest in Fallout 3.

It consists of collecting five holotapes located around the Capital Wasteland to gain entry into the National Guard Depot armory bunker. Although one only needs to collect 4 out of the 5 transcripts to gain entry into the National Guard armory bunker. The tape that is not needed is Tape 1 found in the pylon shack. But it is highly recommended that one goes there because of the mini nuke located there.

Tape 1
Travel to the VAPL-58 Power Station then head north following the electric towers until you reach the pylon shack (it's more like a fenced-in area at the last electric tower), where you will find the tape on the bottom shelf of the bookcase.

This tape is NOT needed to enter the bunker; as it does not have one of the 4-digit code numbers. It simply provides backstory for this quest.

There is also a mini nuke and pre-War book at this location.

Tape 2
Travel to Hallowed Moors Cemetery north of Big Town. Going in at the front entrance, the second Keller tape will be on the left on top of the podium.

There is a captive inside, and a mini nuke on the table inside a wooden crate. Also three frag grenades in an overturned wooden crate behind the table with two ammunition boxes near it. Near the captive there is also a small crate with two boxes of either Abraxo Cleaner or detergent in it; there are two stimpaks underneath them. There is also a Big Book of Science in the podium and a Chinese assault rifle on Makeshift Bedding in the center of the room as well as a D.C. Journal of Internal Medicine on the shelves on the left before the captive.

Tape 3
Travel to the Grisly Diner and head inside, then go to your right and out the back. The third Keller tape is located on a desk at the back (outside).

There is also a copy of Tales of a Junktown Jerky Vendor inside the diner on the first set of racking. Be aware of trap that swings from the ceiling activated by the pressure plate on the floor.

Caution: There are mines around the front and rear of the diner.

Tape 4
Travel to Rockbreaker's Last Gas and look to the west. On top of the hill, you will see the sniper shack, at the top of a cliff; it's the location of the fourth Keller tape. Make your way around the cliff on the southwest side of the cliff (there may be some super mutants/centaurs along the way). Inside the shack, the tape will be on the workbench on the left. (A copy of Dean's Electronics can be found in a box below the workbench, a copy of Guns and Bullets is on the night stand under the pre-War book and the Victory rifle is locked in the very hard locker.)

Tape 5
Travel to Anchorage Memorial and head northwest. Across the river there is a semi-truck and a tent behind it. Inside the tent on the table is the fifth Keller tape.

There can be any type of super mutant (depending on the player's current level) and two centaurs there. There is also a captive inside. The super mutant overlord only appears if you have the Broken Steel DLC.

Reward
Inside the bunker you will find:
 * A Fat Man, known as Experimental MIRV
