Last week’s Nintendo Direct presentation dumped a ton of news about Super Smash Bros. Ultimate, including the reveal of new fighters Simon Belmont and Richter from Castlevania, King K. Rool from Donkey Kong Country, Chrom from Fire Emblem and Dark Samus from Metroid. It also included a tease of content to come: a “mysterious mode” that’s apparently important enough to be included in the Switch game’s main menu.

Thanks to some digital reconstruction by a Smash fan on Twitter, we might know what that mode is called: “Spirits.”
