You are so consumed with looking around, that you don't realize you have become separated from your tour group. With more than 150 miles of tunnels that form an eerie maze beneath the streets of Paris, you find yourself hopelessly lost. While being lost in a creepy, dark maze is enough to spook anyone, the catacombs are filled with bones of more than 6 million people. Can you find your way out, or are you destined to be among those whose bones fill these ancient tombs?
