A relentless survival horror where every sound could be your last…
Trapped in an abandoned building, you are being hunted. There is only one goal: survive.
S-Project 66 is not just another scientific experiment. It’s a waking nightmare, a terrifying trial where every misstep could be fatal. Do you have what it takes to escape?
You play as an independent musician. After a long day, you drift off to sleep… until a phone call suddenly jolts you awake.
It’s your friend, panicked.
“Are you still in there?! Tell me you made it out…”
But you haven’t. You’re still inside. And outside, there’s only silence. A heavy, unnatural silence…
Something is lurking.
Rumors speak of a cult, a serial killer… or worse, an unknown entity.
The hallways are empty, yet you feel a presence. You are not alone.
Run. Hide. Escape… before it’s too late.
