A downloadable game for Windows
The Unknown
The Unknown is a first-person psychological horror experience where survival depends on awareness, instinct.
You wake up trapped inside a dark, decaying apartment. Something is wrong. The people around you don’t behave the way they should. Some of them are human. Some of them are not.
Your only goal is simple: escape.
But escaping won’t be easy.
You are armed, but ammunition is limited. Some entities can be killed — but only under the right conditions. Your flashlight is your lifeline. the atmosphere shifts. When it dies completely, the rules change… and everything becomes aggressive.
Sound plays a crucial role in survival. Footsteps. Breathing. Movement behind walls. You must listen carefully to determine what’s real and what’s hunting you.
