"Those who picked up the collector's edition of Heavy Rain (including myself) will be able to indulge in an extra chapter, courtesy to the exclusive content available. This can be accessed by redeeming the code which came free within the collector's edition on the PlayStation Store.
The Taxidermist is simply a break from the main story, which involves one of the four main protagonists, Madison Paige. Still on the hunt for the Origami Killer, her bosses send her to interview a taxidermist named Leland on the outskirts of town. With the front door locked tight, and an eerie feel in the air, Madison climbs through a back window to investigate at her own peril."
