The Securitron de-construction plant is a location in the northeastern part of Big MT.
There are picnic tables and radioactive barrels just outside the east entrance to the building, surrounded by a torn chain-link fence. On the west side of the building, several letters from the sign have fallen on the ground.
Inside the building from the east entrance, several Securitrons patrol an upper platform, including a unique Securitron named 010011110110111001100101 (which translates into the word "One"). The upper platform leads to a central upper office area with multiple fission batteries on a long desk. Two doors lead to the main deconstruction area. One of these doors leads to the upper office overseeing the deconstruction area. The upper office has a skeleton sitting at a desk.
Inside the building from the south entrance is a lobby area, followed by the main deconstruction area ground floor. A couple of Securitrons patrol this area. The main deconstruction area has a workbench and large amounts of scrap metal and scrap electronics on the disassembly line. Within the main deconstruction area, there is a generator room with a first aid box behind the door as you enter. On the roof of that generator room is a skeleton with a duffle bag and wooden box with some loot; accessible from jumping down onto the roof from the catwalk.
