By now you have likely heard of McKamey Manor. Based in San Diego, California, it's arguably the most infamous haunted house in the world. For years, owner Russ McKamey has been pushing thrill seekers to the physical and mental limits of fear and, reportedly, no one has ever made it through the entire eight-hour experience. Well, this year, Russ has unveiled a new interactive haunt. It's called The Chamber and it sounds (and looks) absolutely terrifying.
