Billion Dollar Bunker: Apocalypse Survival

This one billion dollar bunker is literally floating on springs inside a mountain to survive

the apocalypse. We toured everything from a one dollar bunker that was just a wet shipping

container to a three million dollar backyard tunnel system filled with flamethrowers. It gets crazier

because we found a thirty million dollar underground skyscraper with a pool and a jail,

and even a fifty million dollar mansion buried under a normal house that uses fake light to look

like the outdoors. But the billion dollar military base is the only place safe from

a nuclear extinction. It is so secure they even have their own Subway restaurant inside the mountain.
