Parasite Laboratory is an area accessible from Misty Bridges.
Parasite Laboratory starts off in a small corridor with tanks around the area, along with an elevator. Taking the elevator is another corridor, where the door at the end leads to the containment facility, which has a large vessel containing a parasitic creature. Using the Chainsaw will cause the creature to run amok, causing the facility to transform into a mutated hellscape.
Leaving the containment facility will reveal that the mutation has spread all over the entire laboratory, where the elevators have been transformed into gaping maws. If you exit the laboratory and return, the laboratory will return to its original state.
