Prestigious PP is an achievement/trophy in Dead Rising 2: Off the Record.
Earn a total of 2,000 PP with a single kill in order to unlock this achievement. There are several combo weapons that will allow Frank to achieve this, granted that he has the corresponding combo card.
This can easily be achieved by using the special attack of the Boomstick (Pitchfork + Shotgun) on a zombie. The combo card for the Boomstick must first be earned by obtaining a gold medal in the Sandbox challenge Rooftop Massacre.
