Nintendo's been mum about what exactly is in the big 3.0 update for Super Smash Bros. Ultimate aside from Persona 5's Joker. However, it looks like someone on Nintendo's marketing team done goofed. A new Smash-centric commercial was uploaded onto the official Nintendo YouTube page earlier today, and it revealed a brand new mode within the first seconds of the video.
It's a bit blurry, but from the look of things, Stage Builder will be making a comeback. First introduced in Super Smash Bros. Brawl, players could create customized stages using pre-set blocks, platforms, and hazards. This feature was carried over to Super Smash Bros. for Wii U, where it was expanded upon thanks to the ability to actually draw the stage with the Gamepad. The feature was cut from the release version of Super Smash Bros. Ultimate, but it looks like it won't be long before we're able to create the stages of our dreams once again. Exactly how the new Stage Builder will work is unknown, but considering the exponential improvement it made from Brawl to Wii U, it's probably going to be even better than the last version.
What else will join Joker and Stage Builder in the 3.0 update? No one knows for sure. Many speculate that Home-Run Contest will make its return, or maybe a more traditional All-Star mode is on the way. All we know for sure is that it's swiftly approaching and will probably bring many, many amiibo along with it.
