Amazon Japan has revealed the packaging for the 3DS Extension Slide Pad. We think that's the official name for the peripheral, which we still refer to as thecontroversial 3DS circle pad add-on.
Adding a second analogue controller and shoulder buttons when attached to the portable, the cradle accessory will support games like Monster Hunter 3G, Resident Evil Revelations and Metal Gear Solid Snake Eater 3D.
It'll be released with Monster Hunter 3DS in Japan on December 10, but will also be available on its own for 1,500 yen (about £12.50). A UK release date hasn't been announced yet.
