The comet took the sky. Below the ash, a handful of survivors are counting on you — and up to three friends — to dig, build and keep the lights on.

📖 How to play

1–4 leaders, each on their own phone, run one bunker together in real time. A day lasts 3 minutes: 2 of daylight work and 1 of dangerous night.

Your leader

  • ⛏️ Dig rock next to a tunnel. Finds hide inside: scrap, seeds, water, puzzle boxes… and mutant nests.
  • 🏗️ Build rooms on dug-out tunnels, then help finish them.
  • 🔩 Scrap pays for rooms: dig rock that glints ✨, staff a Workshop, play Scrap Merge there, or scavenge the surface from the Entrance.
  • 🛠️ Work in a room (you count double) or play its mini-game for a big boost.
  • 🧯 Handle incidents: fires, floods, blackouts, breaches, outbreaks.

Your survivors

  • They need 🥫 food, 💧 water, 😴 rest, ❤️ health and 😊 morale.
  • Give them jobs in the farm, purifier, generator, kitchen…
  • Miserable survivors steal, fight, or slip out of the hatch with your supplies.

Winning

Survive the mission's days with enough survivors. Lose everyone, or let morale sink into a day-long mutiny, and the bunker falls.
