...mostly in shops that sells Taiko 3DS2. A new poster design promoting the handheld release will start to appear in game stores from early November (actual period varies by store), coming with a new QR code that grants the Santa Claus outfit. Not only does the outfit injects festive spirits into your drumming experience, but in Space-time Adventure Mode the outfit makes battle enemies drop items more frequently, like the jolly red man eh? (nope)
And another bunch of QR code has been put up on the 3DS2 official site, after their respective campaigns coming to a close, including Gurt! and more. Check them out now!
Also remember that the also wintry tune Do You Want To Build A Snowman is less than one week away, as well as 3DS2's fifth DLC song/quest pack and the next console release of Taiko no Tatsujin Tokumori! (Wii U2), all on November 20!
