On September 30, both the Wii U and 3DS versions of Super Smash Bros. will be getting a neat new addition: a stage based on Mario Maker. It looks very cool.
As you can see, Maker’s giant hand comes in at the start of the fight, whips up a level and then you go at it. Good luck learning strategies for the fights, though, as the stage’s design is drawn randomly each time you play.
