Like Super Smash Bros. Melee and Super Smash Bros. Brawl before it, this year's Super Smash Bros. for Wii U will be playable with GameCube controllers. "Get excited!," Nintendo said on Twitter about the announcement.
The Wii U does not have GameCube controller ports like the Wii does, so how is that going to be possible? As shown in an image today, Nintendo will offer a special adapter, though there's no word yet on how much this will cost or if Nintendo will release a bundle that includes it.
There's also a special Smash Bros.-themed GameCube controller in the image, suggesting that Nintendo might offer that for purchase as well. We have reached out to a Nintendo representative and will update this story with anything we hear back.
Super Smash Bros. for 3DS launches this summer, with the Wii U version to follow this winter. You don't have to wait that long to play the game, however, as Nintendo has partnered with Best Buy to let gamers play a special four-person Wii U demo at stores across the country in June.
Nintendo will hold a special Smash Bros. Invitational event at E3 2014 next month, where 16 top Smash Bros. players will duke it out for the title.
