Abandoned Area

 is an area in The Pitt which is added to Fallout 3 in the add-on The Pitt. It connects The Mill and the Steelyard.

As part of the Mill Worker achievement, 3 Steel Ingots are in a mine cart to the left of the Mill entrance.

This area seem to have been constructed by the Pitt autority to serve as a protection against the Grog who live in tne Steelyard. But the grogs have develloped some strategy to break in.
