Screamcorp

Bottle up real players' screams with your friends
You and your friends work as monsters.
You step through a facility door into a kid's bedroom in the middle of the night.
And if your target screams, you win. But every target is a REAL PLAYER.
And if they scream into their microphone, THEY lose. 
Or you can be the kid, hiding from the monster, desperately trying not to scream when they trigger a jumpscare on you, and if you knock the monster out, you can enter the facility and destroy it from the inside.
It's monsters VS kids.
An asymmetric monster to victim screaming game with proximity voice chat as the lose condition.

You can be the monster, or you can be the kid.

As the monster: enter a facility door, into some random kid's bedroom in the dead of night, you find the kids and scare the hell out of them -- and you catch their scream in a bottle. You can find the kids by searching the house, listening to them talking, and other tracking methods. Once you find them, trigger a jumpscare on them so they scream. You must block the kid from entering the facility at any cost!

As the kid: you are in a house, hide from it with your friends, try to not scream when the monster comes. If you talk loudly into the mic, the monsters (the opposing friend group) will find you, and will jumpscare you. Your goal is to not get caught so you don't get jumpscared and scream. And you may also enter the facility to destroy it from the inside if you get the chance! Crammed in a closet with your friends, holding your breath, praying that door stays shut. And when it swings open? Yeah… you're screaming.

Monsters VS Kids. Who wins?

The roles switch constantly. One moment you're the monster, the next you're the kid getting scared by those you scared just a moment ago.
The winner? Whichever friend group bottles the most screams.
