We got a whole lot of new information in the latest Super Smash Bros. Ultimate-focused Nintendo Direct presentation. Among the announcements was that when the game launches on December 7, it will be available in a bundle called Super Smash Bros. Ultimate Limited Edition.

This version comes with the game itself, plus a Smash-branded GameCube controller and a USB adapter that lets players connect up to four GameCube controllers to their Switch. So far this bundle has only been announced for Europe, though it may come to the US as well. You can pre-order it here for £90.
