I feel like UV can facilitate some tactics that aren't otherwise available. The "invisible" scare actors in Dead Exposure 2008 (not sure if they pulled it off the same way in the sequel) that would hide in plain sight before appearing between UV flashes was a pretty stellar tactic when I saw it. But yeah, UV on its own is just a scenic decision, not a tactic in and of itself.
how do you describe an e-prom?
A sewing machine pedal configured to activate a sound and/or light queue that actors trigger to emphasize the intensity of the scare. Again, not really a “tactic.”
Most of what’s listed are, to me, technical effects or settings and not really “scares.” It ignores the actual actions of the scares. If we want to discuss actual tactics, you need to include.
Ambush or Startle Scare (performer suddenly attacks a guest “from nowhere”)
Distraction Scare (performer draws guest attention while another performer scares)
Ping-Pong Scare (guest scared be multiple performers in a rapid sequence)
Environmental-Blend Scare (Performer disappears in the environment—gillie suits, UV pattern rooms)
Stalking Scares (when a performer scares a guest, disappears for a moment, then scares them again)
Follow Scares (when performer obviously follows a guest)
Stealth Scares (silent scares, where performer just “appears” beside you).
Alternate-Level Scare (from above or below guests)
Wait (performer is seen by guest well in advance, and patiently waits for guest to approach)
Team Scare (multiple performers conducting an ambush scare simultaneously)
Multi-Layer scare (a distraction in the distance allows a startle in-between the guest and distraction—think the door scare)
Subversion scare (what you see isn’t what you get—think scrim scares, fake arm scares, etc.)
Character scare (performer who’s primary function is establishing the narrative more than “scaring;” though scaring is possible)
Choreographed scare (performer acts out a specific scene coordinated with designed effects—Boris’ gunfight)
