No one really knows what happens in the Chemical Plant, because the whole area is toxic to human life. However, you will not have any effects placed on you if you enter the plant. Rumors filter through to Freedom City that a machine is housed here, capable of transforming common dirt to GOOOOLD. Tuskers and hogs have made their home in the southern areas of the chemical plant, aggressive to any intruders.
The chemical plant may be reached by going west from southern slagtown.
