Sewer (metro)

The sewer is an underground link between Pennsylvania Avenue and Seward Square. It is part of the Metro system under the Capital Wasteland, but the end points have fallen in and it can only be accessed from sewer grates.

Exterior
The two entrances to the Sewer are not very obvious. One is in Seward Square and the other is in Pennsylvania Avenue.

The location of the Seward Square entrance is across the street from the Seward Sq. North Metro in an alley that spawns a combination of 3 super mutants and/or cantaurs. Two meet you going to the Sewer grate and one spawns behind you as you reach the grate.

The Pennsylvania Avenue entrance is very close to the Metro Central map marker. From there, head north around the other side of the station to the diner. Go west through the opening in the ornate wall and veer northwest around the corner. As soon as you get past the rubble and reach the paved street, look to the right (north) for a grate on the sidewalk next to the rubble.

Inside
The Sewer interior is a medium-large size metro tunnel, with 3-4 super mutants and a high possibility of spawning multiple super mutant overlords if one has Broken Steel. A door inside the tunnel opens up on a room, located in the middle of the local map, with stairs that leads to a small upstairs area with several skeletons and a holotape.

Notable loot

 * Hidden stash note in the southern room, next to an AEP7 laser pistol, microfusion cells, and three skeletons.
 * Tumblers Today next to the hidden stash.

Appearances
