Brown Town was a map included in the first version of Metal Gear Online included in Metal Gear Solid 3: Subsistence. It was a large town area. It was later ported on the second version and renamed Coppertown Conflict.
It contained two underground halls to the north, a loading/storage area and an office area to the northwest, a garage just southwest from the western entrance to the first underground hall, a store immediately south of the garage, a main street immediately south of the southern entrance to the first underground hall, a second level office near the office area, an open area to the easternmost point, and a theater to the absolute south of the map.
In the Japanese version for the Metal Gear Solid: HD Collection, there was an incomplete map among the data files that, based on the file names, was intended to be a variant of Brown Town in the final version.[1]
