We're back to reveal the most savage, most innovative and most effective weapon of human history. If you didn't catch part one where we describe all the competitors please go back and listen. We'll be right here waiting... waiting... waiting... ok ready? You didn't skip any parts did you? Did you? 

Enjoy. 

In the name of misery and death, humankind has created (ok so mankind, men are the only ones sick enough to create such bludgeoning devices) some of the most innovative ways to kill each other. But what has been the most effective? The most catastrophic? The most expeditious? Sure there are more than one ways to skin a cat, but how many different ways have we killed our enemies? From ancient Chinese dynasties to Native tribes in the Americas to Egyptian battlfields, tune in this week for a March Madness showdown bracket-style as we break down some of history's best (or worst rather) killing machines.
