Real estate agent Robert Vicino is selling about 200 spaces in a 13,000 square-foot Vivos underground bunker (originally designed as a cold war communications center) for $50,000 per person. He says he's gotten deposits on half of the spaces. His website has photos of what the shelter will look like after it's been renovated.
From the Vivos website:
The central theme to all end-of-the-world scenarios is to find shelter underground. The soil of the Earth itself can provide the best shelter for most catastrophes including a pole shift, super volcano eruptions, solar flares, earthquakes, tsunamis, and asteroids, as well as potential for many more manmade devastations such as nuclear bombs, bio terrorism, chemical warfare, and even the return of Planet X (known as Niburu or Nemisis) and the solar disturbances it will cause.
The Vivos complexes will be deep underground, airtight, fully self-contained shelters designed to survive virtually any catastrophe, or threat scenario including natural disasters, a nuclear blast, chemical and biological weapons, or even social anarchy. Each self contained shelter complex will comfortably accommodate a community of 172 – 200 people, in spacious quarters, for up to 1 year of autonomous survival to ride out the potential events. Every detail has been considered and planned for. Members need to only arrive before the facility is sealed and secured.
