Laith "SDX" Hamdan has released a tutorial video detailing a newly-discovered advanced technique in Super Smash Bros. Ultimate: an instant wall jump from ledge. The technique was first discovered while watching match footage of Gonzalo "ZeRo" Barrios, who performed the technique seemingly by accident. After going over the footage, SDX quickly set to work figuring out how to replicate it, producing a video on his findings.
SDX notes that, while flashy, the technique doesn't seem to have many practical applications. Cloud also seems to be the only character the technique works with, and even then, it doesn't work on Pokemon Stadium, Lylat Cruise or the left side of Town & City.
