The new content will march to the consoles this winter as paid DLC. It will cost you 1,200 MS points on Xbox Live and $15 on PSN. This DLC will unlock brand new explorable areas, terrifying boss fights, standard enemy types, characters and equipment.
Additionally, Namco Bandai confirmed that Prepare to Die Edition will be available in North American through Steam. This is, in fact, a response to the growing unrest in fans to the initial announcement of Games For Windows Live integration. Hopefully, this move will encourage more fans to try this game on PC.
