“They said fear could be cured. They said the mind could adapt. So they kept them awake… and then they never slept again.” 
Deep in the frozen forests of the Urals lies Novokirsk, a Soviet town erased from every map. Once home to Project Zvezda, an experiment meant to weaponize fear itself, it now lies buried under snow and static. But the signal never stopped. It remembered. It learned.
In ENTITY UNKNOWN, you awaken alone in the ruins of this forgotten place, surrounded by decaying laboratories, frozen classrooms, and towers still pulsing with the same frequencies that drove everyone here insane. There are no weapons. No HUD. No escape. Only the hum of the signal. The flicker of your flashlight. And the feeling that something is watching from within the dark.
• Explore the erased town of Novokirsk, frozen in time and haunted by the remnants of a Cold War experiment.
• Experience fear as a living mechanic, the darker it gets, the more your perception collapses.
• Light, signal, and sanity become your only lifelines as the world warps around your unraveling mind. Every light is a heartbeat. Every sound is a warning. And every time you realign the signal… it realigns you.
The subjects stopped dreaming. Their eyes stayed open. And when the last light went out… it woke up.
ENTITY UNKNOWN is a cinematic, narrative-driven psychological horror, a descent into isolation where fear itself has become conscious. The experiment never ended. The signal is still broadcasting.
Wishlist ENTITY UNKNOWN on Steam today.
