Flooded Metro (exterior)

 shows up on the Pip-Boy 3000 world map in two places:


 * The Flooded Metro marker north of Arlington Cemetery (shortly southwest of 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. (See Arlington/Wasteland Metro.)


 * 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 may be necessary. It also has a very high complex of stairs leading downwards, breaking into small rooms near the beginning. Be warned that there is a shaft in the middle of this complex; resist the temptation to jump the railing, it's a long fall.

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 with a trail of blood going behind it, 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.
 * Tumblers Today and Pugilism Illustrated in the Raider camp southeast of the southern entrance. Also a Nuka-Cola Quantum.
 * Near a shaft close to the Mason District, through a tunnel to the east, is a rigged shotgun booby-trapped chamber (A). On a barrel in this chamber is The Shocker with instructions. The chamber contains a Nuka-Cola Quantum laying on top of a gun cabinet, two ammunition boxes on the shelves next to the cabinet, and an average-locked safe at the base of the bed.
 * At the top of the shaft go west. You should see a water tank surrounded by a fence. Past the tank, on the right (B) is a small room with lockers. On the top of one of them is lying a RadAway and in a cabinet you will find a laser pistol with ammo.
 * At the bottom of the shaft behind the mirelurk egg clutch along the south wall is a gun case with a laser rifle and ammo.

Appearances
The Flooded Metro only appears in Fallout 3.

Bugs

 * This area has severe clipping issues (objects falling through floors etc.) that can occur anywhere. These include mirelurk randomly appearing.
