Nintendo announced today that it will be releasing the DLC for Lucas, the Miiverse Stage and the Splatoon Mii Costumes for Super Smash Bros. for 3DS and Wii U on June 14th.
Also, a K.K. Slider Mii Costume will be coming at a later date.
Here’s a screenshot gallery for you to take a look at the new additions:
(I think the fact we got Lucas before E3 kind of damages our chances of getting a Mother 3 localization announced… well, better luck next time, I guess!)
