The World Championship C-Gear, which has been released in the US and the EU but we apparently did no post about is now available in Japan. Just go grab it at the Global Link. It runs as of today until September 25th, which is only one month. If you haven’t got this one already for your international games, you can grab it with the password WCSCGEAR2012.
This C-Gear ties into the Beginning Cup, a tournament where Japanese BW2 owners can with the Pokémon of the extended Unova Dex. Registration is now open, and closes Thursday, with the tournament straight after that. So be sure to register if you want to take another chance at battling strong trainers!
