The year is 2066.

The Earth's surface has long been uninhabitable. Humanity has survived thanks to a system of underground bunkers, cut off from a world ravaged by disaster.

A group of volunteers sets out from the main bunker on a dangerous mission to obtain supplies. Eleven kilometers from home, everything starts to fall apart — the air filters run out, they lose contact with the base, and returning becomes impossible. Forced to make a desperate decision, they seek shelter and find a smaller, abandoned bunker. It is their only chance for survival.

• Realistic Survival Mechanics:
  Manage food and water intake, as every item affects your health in different ways. Poor choices can lead to deteriorating mental health.

• Mental Health System:
  Your psychological state is just as important as your physical health. Pay attention to your mental well-being by resting, taking medications, or listening to music. Neglecting this can lead to severe consequences.

• Exploration:
  The shelter isn’t as small as it seems. Explore every corner to find resources, hidden secrets, and essential items that could be the difference between life and death.

• Fuel Management:
  Keep the shelter’s generator running by finding and using fuel. Without it, the shelter’s systems could fail, leaving you in the dark.

• Maintenance:
  The flashlight’s battery life and other important devices need regular attention. Make sure you have replacements when necessary, or face the consequences of malfunctioning equipment.

  • Food and Water Impact:
    Each food or drink item affects your health differently. Pay attention to what you eat to avoid health issues that can affect your survival chances.

  • Music for Sanity:
    Listening to music helps maintain your sanity. Explore the shelter to find radios or other devices that can play tunes, keeping your mind intact.

  • Deteriorating Environment:
    Time is a critical factor. As you stay in the shelter, your supplies and energy will dwindle. You must constantly adapt and make smart choices to stay alive.
