Mass Chemical is an unmarked location in the Commonwealth in 2287. It is located southwest of the BADTFL regional office.


The building itself is uninhabited, but meat bags indicate a super mutant affiliation. On the lower level is a utility protectron inside a pod, controlled by the terminal (Novice) nearby. By following the ramps up, one can find a chemistry station, a weapons workbench and an exit to the roof.


  • Once activated, the protectron will exit and wander over to the large construction building to the south, attacking any super mutants present.
  • There is a super mutant sitting on a wooden box on the roof.


Mass Chemical appears only in Fallout 4.
