Mason District South

is part of the Metro system under the Capital Wasteland. It gains access to the Flooded Metro.

This seems to be the closest route to the Shocker, a special Power Fist. After entering the station, take the only door and continue down the tunnel to the first door on the East. Expect Mirelurks, including a king, while heading down the stairs. Take the first opportunity to open doors into a tunnel heading East. Watch out for mines while following it to a partially flooded irradiated room with various loot. On top of a barrel is the Shocker and the Shocker Glove note.
