A year after the disaster, the bunker's life support systems fail critically. Communication with the outside world is completely lost. You are a mechanical engineer, awakened in your quarters by a piercing siren, alone and cut off from the world. You must descend into the depths of the bunker and come face to face with the nightmare that lurks within its walls.

Immerse yourself in an atmosphere of claustrophobic horror:

Maze of Fear: The Bunker is a tangled maze of dark corridors, flooded compartments, abandoned laboratories and claustrophobic ventilation shafts. Every rustle, every drop of water, every glow from your flashlight will keep you in constant suspense.

Psychological thriller: You are alone against the unknown. The enemy is invisible, playing with your sanity. Hallucinations become more and more real, whispers from the vents call your name, and shadows dance on the walls. Can you keep your sanity in this realm of paranoia?

Fragments of the past: Collect scraps of diaries, notes, documents to reconstruct the chronology of events and understand what happened to the inhabitants of the bunker. Every fragment you find is a step towards unraveling a terrible mystery.
