Escaping Hades

In old Greek mythology, there was a man named Heracles that had not only defeated the mighty Cerberus, the "guard dog" that sat at the gates of the Underworld, but had entered and escaped the Underworld, the realm of the god Hades. Granted, the man was the son of the god Zeus, but that's an arguement for another time. My question is can I do the same? If so, at what cost? Rated M
