Mute City SNES was a retro stage in the 3DS version of Smash 4 and it returns for Ultimate. It’s obviously based on F-Zero on the Super Nintendo.
Though I’ll admit, it’s very imbalanced. You basically fight as the cars are moving.
The biggest thing to avoid is landing on the road. It packs a harder hit than most foes.
It’s far from my favorite stage, but I like it a little.
