Phoenix and a beautiful psychic named Raven came to the nuclear graveyard of Houston to find the key to treasure. But they were captured by the Dark Messiah's stormtroopers and forced to play Metalstorm. Its rules were simple: there were none. And the winner? No one knew, for no one had ever survived.
