This new DLC has been rumored for a little while and now, Nintendo's Smash Bros site has officially confirmed that the 3rd wave of Mii Fighters costumes is now available for purchase and download.
Just IMO, but I think personally that Nintendo may be overdoing the Mii Fighter costumes a tad, and why hasn't their been a Mario, Luigi, Wario & Waluigi overalls costume set yet? That needs to happen. But that's besides the topic, Nintendo has released new Mii Fighters costumes today.
Just to name a couple of them, there's a Bear suit, an SSB hoodie, a King K. Rool suit, a Flying Man suit and a Samus suit. The one that strikes me as truly odd is the bear suit.
Game on and Keep it Rehl!
