About the Game

Mysterious deaths kept happening, and then suddenly, a suburban hospital shut down.

As a journalist, you step into the abandoned hospital to uncover the truth.

Scattered throughout the hospital are 10 medical records. Collect them and find your way out.

But there’s one problem… You’re a total coward.

The only way to run is to scream—and push yourself forward.

Shout your way to the finish!

Game Features

🔊 Mic Input
Scream into your mic to run.
Running away from enemies by actually screaming makes the experience even more immersive.

(You can play without a mic, but you won’t be able to run, making the game much harder.)
(Normal movement is done with WASD.)

🌍 Online Multiplayer
Play with up to 4 players!
Scream together with your friends.

Bring a healing item to your fallen friend and help them recover.

🎙 Proximity Voice Chat
Talk to your friends while playing.
If you hear a scream in the distance… run for your life!

👀Sound-sensitive Enemies

Enemies react to sound.

If they hear your voice or noises you make, they may come toward you.

If you make a noise, it's best to get away from that spot immediately.
