Arlington sewer

Arlington Sewer is an unmarked location in Fallout 3. The sewer is a small underground area located to the south-east of the Arlington Library and 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.

Inhabitants
The sewer seems to serve as a Raider base, and contains approximately six hostile Raiders of various levels. The Raiders respawn every few days, so returning here every now and then could get you lots of Raider gear and weapons.

Notable 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.

Appearances

 * The Arlington Sewer appears only in Fallout 3.
