The Underworld Metro Path is a hidden location within the Fallout 3 online game. It’s a secret underground railroad that connects the Underworld, a ghoul-populated space, to the remainder of the Capital Wasteland.
The trail just isn’t marked on any map, and it’s simple to overlook. To search out it, the participant should journey to the Meresti Metro Station and search for a small, unmarked door behind the station. The door is locked, and the participant might want to choose it to get inside.
