Exclusive to Amazon.it pre-orders, the game came with an RPD patch. The patch was placed on the front of the already sealed game with SIAE sticker, and an additional layer of shrink-wrap was applied. A DLC code for the Chris and Jill versions of the Samurai Edge was also included, distributed by email.
While not confirmed, the game itself is probably the regular edition.
