Heavy Rain's Story Will End If All Four Characters Die

Heavy Rain writer David Cage has revealed that if you manage to get all four of main character's killed by the final third of the game, the story will end:

“When all of the characters die, the story ends – that’s quite a sad ending."

“There are movies with happy endings and sad endings. In Heavy Rain, it is up to the player to tell his own story and decide what story he wants to tell. This kind of ending cannot happen before the last third of the game, so the experience won’t be too significantly shortened.”
