From the Nuclear Threat Initiative:
While the mineshafts leaders retreat to at the end of 1964’s apocalyptic film Dr. Strangelove seem like dystopian science fiction from the Cold War, both the United States and Russia spend a fortune every year to maintain and improve an extensive complex of underground bunkers.
These sites are designed to maintain continuity of government during a nuclear war, even while the people those governments represent perish. To explain the scale of these facilities, we have reconstructed two, the U.S. Raven Rock and Russian Kosvinsky sites, roughly to scale using the popular immersive gaming platform, Minecraft.
You can play Minecraft in our models of American and Russian bunkers:
