A dark sci-fi horror where ancient rituals intertwine with secret Soviet experiments. Explore atmospheric tunnels, hidden laboratories, and abandoned shrines inspired by real locations—and survive by solving intricate, mind-bending puzzles.

You are a college student who has just moved to a big city in search of a new life. But instead of a fresh start, you begin to suffer from recurring nightmares. In your dreams, you see a mysterious hill. It’s calling you.
Each night the visions grow more vivid: underground tunnels, abandoned structures, and a strange device that once kept something contained.

Trying to understand what’s happening, you uncover classified documents hidden in the city archives. What you discover leaves you with only one choice — go to the hill yourself.
The only way to end the nightmares is to reach their source. But not everything buried underground should be awakened.

A dark atmospheric horror experience inspired by real locations. Explore the remains of an old fortress, labyrinthine tunnels, a shadowed forest, and ancient shrines hidden beneath the hill.
Investigate your surroundings, piece together fragments of a buried truth, solve environmental puzzles, and navigate dangerous terrain with light parkour elements as you descend deeper into the mystery.

Every discovery brings you closer to the truth — and to an ancient horror that has slept beneath the hill for centuries.
Your decisions will lead to one of three different endings.

Created by a former Lead Level Designer of a major AAA Chernobyl-themed project, with a strong focus on immersion, tension, and environmental storytelling.
