Remembered this post here at N-Handhelds? Yep. In Japan, if you are one of those individuals who registered 2 Nintendo 3DS titles at Club Nintendo, not only will you get the chance for a special themed Nintendo 3DS, but you get to have a free download of Kid Icarus too!
But if you haven't you can still get the chance to download the first game in the franchise for 600 yen on January 18.
