Old Olney underground

 is a place added to Fallout 3 with the DLC Broken Steel, accessed via a ladder in Old Olney Sewer.

As part of the quest Shock Value the Lone Wanderer passes this area to reach the Olney Powerworks. It is inhabited by ghouls Kidd and Wint and a lot of Deathclaws. The ghouls (along with several more now-deceased friends) tried to establish a colony here, but disturbed a Deathclaw nest. Kidd and Wint were the only survivors.

The area can be described in four small subsections:
 * The first is the home of Kidd, Wint and their ghoul compatriots.
 * The second area is a hospital, inexplicably stocked with a small number of Nuka-Cola Trucks.
 * The third area is a utility section under the hospital, which contains quite a few Custom-built weapon components, such as two Cherry Bombs, a Lunchbox and plenty of Turpentine, Abraxo Cleaner, and other components along with two workbenches.
 * The fourth area is a short tunnel and another utility section leading to Old Olney S. Wilson Building.

Appearances
appears only in the Fallout 3 DLC Broken Steel.

Notable Loot

 * A Mini Nuke is found underneath a Teddy Bear next to a cupboard full of children's toys. The room is located behind the Lone Wanderer after he/she meets the first Deathclaw on the ramp. When at the top of the ramp, turn around to see a small gap in the wall to the right. After entering the room you will notice the broken door so the gap in the wall is the only way to access the Mini Nuke.


 * A Nuka Cola Quantum can be found behind a ham radio, which is behind an average locked cell door. The door is in between two columns surrounded by rubble that split the path to continue onwards. It is near the counters with a workbench on it, underneath the Hospital area, before the mine that blows up the rubble blocking the tunnel.


 * A Sniper Rifle can be found behind some arching pipes next to two explodable generators within a chain-link fenced off area, with a workbench to the right of the rifle. There are a couple boxes of .308 ammo in front of it. Continue further from the area of Nuka Cola Quantum and you should come across the area. It is near the southwest corner of the map.
