Underground maps

Shortly after the Great War, the Commonwealth's underground is a labyrinthine system of former metro stations, subway lines, access tunnels and sewers with different factions and isolated groups of survivors inhabiting it alike.

Large segments of these lines, usually identified by the color of their wall tiles, have been claimed by some factions as their territory, with most of them not taking well to intruders.

Many of these locations can be confusing, and navigating the network is hampered by a lot of them sharing generic names like "Subway Line".

The following maps, while not (yet) presenting a conclusive picture of the network, are supposed to **help** survivors **navigate** the maze, but **will not provide more detail than needed for this purpose**.

Notes:

* Map orientation is as seen in the Pip-Boy.
* Some waypoints on these maps have been documented to ease navigation, not because they are special in any way unless noted otherwise in the legend.
* Since many of the locations carry generic names, all locations in this list in addition to their in-game name will also carry what the game engine calls "EditorID" (sometimes also referred to as "CellID"), representing their technical identifier.
