The Heavy Rain Chronicles were intended to be a series of short, downloadable prequels to Heavy Rain. The only title released was Heavy Rain Chronicles: Episode One - The Taxidermist. The Chronicles were cancelled after one episode due to resources and time being allotted to adapting Heavy Rain to the Move system. Strangely, the DLC is only included on the PlayStation 3 release of the game; the PlayStation 4 remaster and PC releases do not contain it.
The Chronicles were meant to explain how Norman got his cheek scarred and became addicted to Triptocaine, as well as how Madison developed her insomnia, although the events of Episode One could explain this.
In 2010, Quantic Dream announced that development of the Chronicles was on hold. In 2012, the company announced the upcoming release of their next title, Beyond: Two Souls, at E3, further lessening the chances of the DLC. Beyond: Two Souls was released in late 2013 with no further news on the Heavy Rain DLC.
