Build a Bunker

Dig deep. Get rich. Build the ultimate bunker!

Start with a tiny Supply Stand on the surface and turn it into an underground empire. Click to sell, upgrade your businesses and hire managers (your Roblox friends!) to run them while you dig deeper.

⬇️ 8 businesses to unlock: Supply Stand, Ration Factory, Water & Power, Research Lab, Drone Armory, Reactor, Command Center and the mysterious Xeno Lab.

💰 Earn enough and Mr. Rich lands by helicopter to invest. Rebirth for Investors: each one boosts your cash by 1%. Spend them on Powers like Manage, Run Faster and Stack Upgrade.

🚀 Evolve your bunker from Concrete to Steel, Titanium, Magma, Alien and Golden, with x42 income speed every time.

☢️ Ride out the Radiation Storm for x4.2 income speed, take deals on your bunker phone, and collect what your managers earned while you were away.
