Secret Lab Cleaner is a dark horror simulator where fear manifests itself in the smallest details. The player is assigned to work in an underground complex, where simple cleaning becomes an act of survival. An AI named ANNA speaks to you like a child, but knows too much. The assignments are strange, the objects take on a life of their own, and the air is thick with anxiety and the whisper of ventilation. Voidstep In the depths of the complex, reality loses its meaning. The sound of footsteps fades, the lights flicker, as if trying to blink. Something moves beyond the doors — without form, but with intent. It remembers routes and reacts to breathing. Every action carries weight: sound, movement, light can become a death sentence if concentration is lost even for a moment. The audio design creates tension without a single jump scare. Metal creaks, the air vibrates, and the AI's voice becomes a haunting echo in the mind. The lab is like an organism that refuses to be cleansed. There's no room for heroic deeds here — only the endless wait for the shift to end and the hope that the elevator will finally go up. Features of the game An atmospheric horror without the usual fear tropes. An AI companion with increasing unpredictability. Mechanics of sound, light and movement as elements of survival. An immersive environment that reacts to the player's actions.
