The Scott Pilgrim DLC has been on the PS3 for a good while now. The DLC contains additional Playable character Knives Chau, Drop in Co-op, and new Battle Royale and Super Dodge Ball esque mini games. Meanwhile, the DLC has finally been released on Xbox 360 to coincide with the release of Scott Pilgrim vs The World: The Movie in the UK. However, there have been various reports that after purchasing the DLC, none of the content is avaliable. This seems to do with an automatic update that the game requires after purchase however it is unclear as to whether this is the case or not. I bought the DLC today and have had no problem with the content so far however you may want to wait to get an official word about that.
