Scariest Feature: Having revolting things inserted in your mouth by strangers

Is Blackout the most intense haunted house in America? The elaborate waiver you sign before entering, which says you can expect "extreme horror, adult sexual content, tight spaces, darkness, fog, strobe light effects, exposure to water, physical contact, and crawling" indicates yes loud and clear. Rather than watching a performance from the periphery, Blackout immerses you in your fears, making you a prisoner to them. You enter alone and are given a "protective mask." You're then violated, groped and forced to put things in your mouth, until you're so terrified by the S&M-inspired scares that you scream the safeword. Yes, you're given a safeword.
