Ceiling Vents

The Vent System in the Ceiling is not visible to the Camera System because the Radioactive waste would either Block the View or just Mess up the Camera Feed. There is a Character in the Vents, The Mutant, As He Moves around the Vents, He Bangs on the walls of the vent and Growls

Trivia

 * There was a time that the creator was gonna make a Rooftop Camera so you could see the Vents but due to the surrounding area being empty. it was Scrapped
