Sony's just announced the the DLC for Heavy Rain that people who pre-ordered have already played will be available to all-comers... on April 1st for $4.99 USA money.
Called 'The Taxidermist' it features Madison Paige. Let's hope it explains that thing that happens to her early on with the...
Anyway, this is what Sony has to say, "The Taxidermist chapter provides an additional backstory to Heavy Rain and features one of the main characters from Heavy Rain, journalist Madison Paige, on one of her early leads from her investigation into the Origami Killer.
In a similar manner to the unique, cinematic gameplay style of Heavy Rain, you will play Madison, and be presented with a number of tense situations and decisions, as she digs further into the case, which of course, will determine one of many different outcomes."
We doubt this means a new killer or killers but we can hope.
