The Setup: DNF’s premise is simple. Since he last “blew up aliens good”, Duke has become a fulltime playboy living in the penthouse of his Las Vegas casino. When the aliens return to earth but initially does not attack there is some political debate on how to handle the situation. It is believed by some, including the President, that Duke was the cause of the last attack by striking first. Just as it looks like DNF’s story might be getting heavy, the aliens launch an assault, Duke punches of them in the nads, and we’re back to killing anything that isn’t human.
