Early this morning, Nintendo shared some interesting news on Twitter. @NintendoEurope tweeted: Mewtwo will be available to purchase later in
#SmashBros, for those who don’t register both versions..
Through a special promotion with Club Nintendo, those of you who buy both the 3DS and Wii U versions of Super Smash Bros. will get Mewtwo along with the game’s soundtrack.
As of right now, there is no pricing for Mewtwo or expected release date. Club Nintendo says the free download of Mewtwo, for those who qualified, will be sent out in “spring 2015.”
You can see the North American announcement and how to redeem the games for the codes on Club Nintendo’s website.
