About the game
The war ended in a blinding flash. Now, the earth is hollow, a fractured shell hiding the remnants of humanity. A new era of evolution is about to begin. Survivors fled underground, but salvation was a lie. A sickness spread, warping minds, twisting bodies. No one is being spared.
You are a child, taken to a hidden facility deep below the surface. You don’t know why. Only that you’re sick. That everyone is. And something is wrong.You have to escape. Crawl through the vents. Follow the echoes to get to the surface. Your mother is waiting for you.
Wander through a decaying underground facility where nothing feels stable. Every room hides secrets, every object whispers fragments of a story you were never meant to uncover.
The bunker is not empty. Strange figures linger in the shadows, some helpful, some deceptive, none entirely trustworthy. Their words may reveal truth… or bury it deeper.
A labyrinth of vents and passages twisting into the dark. Something moves inside, creatures that stalk and listen in the silence. Paths split, shift, and close behind you. There is no turning back.
Though your journey branches in countless directions, they all lead toward the same haunting revelation. What you find depends not just on where you go, but on what you dare to see.
