Arlington sewer

Arlington Sewer is an unmarked location in Fallout 3. The facility is a small underground area located to the south-east of the Arlington Library which seems to serves as a Raider base, and contains 6 hostile raiders of various levels.

The sewer is divided into three levels, with two guard rooms and a locked storage room on the bottom level. The storage room can be accessed by a terminal and contains a safe, armor crate, and two ammunition boxes.

Loot

 * Three Chinese Assault Rifles located on a table in the first floor room.
 * Scoped .44 Magnum in the locked safe on the bottom floor.

Bugs

 * Followers can sometimes spawn in the wall to the left once you first enter this location.
