Flooded Metro (exterior)

 shows up on the Pip Boy World Map in two places:


 * The Flooded Metro marker up by Arlington Cemetery (and a short walk from the Anchorage Memorial) is blocked by debris when going down the entrance ramp, but a door on the right takes you through offices and then maintenance tunnels which come out on tracks next to some stairs which go up to the Arlington Cemetery.


 * The Flooded Metro near the Southern border of the map is West of Arlington Library (halfway to the Nuka-Cola Plant) and across the street (North) from a raider camp. This metro is mainly caved in, and is a maze of utility tunnels and shafts filled with Mirelurks of all types. Heavy firepower is needed.

Notable Loot

 * When entering from the south (not Mason District South!), following the tunnel up right, the first room has a Guns and Bullets behind a transformer, near a skeletal corpse. In the same spot is also a Scoped .44 Magnum and some ammunition.
 * A Pulowski Chamber outside the metro near the south entrance (not Mason District South) contains a Chinese_Army:_Special_Ops_Training_Manual
 * Near a shaft close to the Mason District, through a tunnel to the east, is a booby-trapped chamber (A). On a barrel in this chamber is The Shocker with instructions. The chamber contains some other weapons and ammo as well as a Nuka-Cola Quantum.
 * In an egg chamber down a staircase-lined square pit, ankle-deep in water, there is a gun case with a random weapon (Laser Rifle and Microfusion Cells, etc).
