From the introduction: Session Zero is a game about characters. It is the story of the life they have already lived before your story with them begins. It is who they are, who has helped them, what has benefited them, and what has caused them harm. User summary: The game uses special Session Zero cards, but a standard French-suited pack of cards can easily be substituted, using tables included in the game. The game is distributed as a game document and a ZIP archive containing numerous print-and-play card images.
