A new Smash Bros. release almost guarantees a newly designed GameCube controller will come with it, and Super Smash Bros. Ultimate is no exception. Recently announced, the latest GameCube controller is now available for preorder.
For the low price of $30, you can snag the controller on Amazon. However, Amazon has also opened up preorders for the GameCube controller adapter. The adapter costs $20 and will ship the same day as the controller.
It’s worth noting the current release date is listed as December 28, 2018. While it is likely a placeholder date to be corrected later, keep in mind it may not be, so if you want your controller or adapter on release day for Super Smash Bros. Ultimate, you may have to look elsewhere.
