Flooded Metro

Flooded Metro marks access to a Metro tunnel with the same name in the southwest of the urban DC area, between the Arlington Library and Red Racer Factory.

A large Raider camp is just to the southeast of this location, across a road full of cars.

Note: It seems that this peculiar location MIGHT have an average higher chance to spawn the Firelance random encounter (2 random encounters on 3 different playthrough session resulted in this encounter, accompanied to realted problems in finding the Alien Cell due to the exploding cars and the wrecked cars ( needs verification, tested on Xbox 360 version).
 * You will likely have a Random Encounter here.
 * There is a "false" map marker named Flooded Metro. In reality the northern marker is the entrance to Arlington/Wasteland Metro from the vicinity of Wilhelm's Wharf and Grayditch.

Notable loot

 * Chinese Army: Special Ops Training Manual in the Pulowski Preservation Shelter close to the escalators.
 * Tumblers Today in the raised part of the Raider camp. Watch out for Raider with Flamer or Missile Launcher.
 * Pugilism Illustrated on the makeshift kitchen table in the Raider camp.
 * Nuka-Cola Quantum next to Pugilism Illustrated on a desk.
 * The Shocker, a unique Power Fist and a Nuka-Cola Quantum all the way down inside the Flooded Metro tunnels.
 * Guns and Bullets next to some .44 rounds inside the Metro tunnels.
