In an interesting turn of events, Namco Bandai has announced a special promotion. This promotion will bring collaborative items to the vita version of Katamari Damacy.
Currently anyone can request an item to appear in the game. This includes celebrities nominating themselves to appear. If you have a request simply head to their official site and give it a go. Please note that these maps will appear in other regions.
This promotion will last till December 1st and winners will be announced mid December. The DLC however won’t appear till March 2012 or later.
