How would Ghostface even work?
I'm having trouble understanding what Ghostface's power would be in this game because there was never anything supernatural about him, and his main thing was just stalking and then chasing people into a corner like Michael, but much faster. At least Amanda has the RBT's and Leatherface has his chainsaw without necessarily being paranormal killers I guess. Ghostface usually only ever used his combat knife as a weapon though. I've seen people suggest something that involves phones but why would the survivors pick up the phones if they new it was just Ghostface calling to check in?
I suppose they could have it where survivors spawn in with 90's cellphones on their hips and they can't do anything to remove them. Ghostface could dial a number and get a visual and audio que like you do when someone fast vaults or misses a skillcheck. All four phones continue ringing and revealing the estimated locations of all four survivors until one survivor answers the phone and the one survivor who answers the phone has their aura revealed to the killer for a couple seconds or maybe they scream when they answer the call. When one person answers the phone, the ringing to the other survivor's phones stops until Ghostface initiates a call again. There could be an Ultra Rare add-on that makes it so the ringing continues for all survivors even after one person answers the phone, and it doesn't stop until every survivor answers it.
To put the add-on simply, each survivor would have to answer their phones in order to stop the ringing even if someone else answered their call. It could make him a lot like Doctor but maybe have a much greater range than the Shock Therapy and his terror radius is on 12 meters without any add-ons or perks to boot. There could also be cellphone battery add-ons that reduce the cooldown time it takes between each time he can make a call. The power could also only trigger one cell phone to ring unless he has an add-on that allows "Group Calls".
