We're still two weeks away from Super Smash Bros. Ultimate's official December 7 release , but Nintendo is already struggling to squash holiday weekend leaks of everything from the game's animated cut scenes and hidden content to its massive, remix-filled soundtrack.

The earliest evidence of the game's availability "in the wild" dates back to a Wednesday post on 4chan showing an image of the game's purported retail packaging. In the following days, further online reports suggested that the game was being sold early and relatively widely at certain Mexican retailers.

From there, it was only a short matter of time before pirated versions of the game's data were leaking on to the darker corners of the Internet (thanks in large part to the unpatchable Switch hacking method published earlier this year). That in turn led to streamers showing off spoiler-filled demonstrations of the still-unreleased game on Twitch and YouTube. Nintendo has been working to take down many of these streams with copyright claims, but archived versions are not very difficult to find online as of this writing (we won't be providing direct links here, though).

Meanwhile, data-miners have been trawling through the game's data with hex editors to extract any and all hidden content, from lists of stage names to the hundreds of unlockable assistive "spirits" drawn from Nintendo history. The Smash Bros. subreddit has a relatively "spoiler safe" list of links to that kind of extracted information, with the caveat that "known dataminers are mixing in 'troll' information with their tweets, take anything without evidence with a grain of salt."

YouTubers have also been uploading copies of the game's 100+ remixed Nintendo theme songs extracted directly from the pirated files. While Nintendo is issuing copyright strikes and YouTube ban requests for these uploads, mirrors of the soundtrack remains relatively easy to find online as of this writing as well.

The leak reveals incredible twists to classic songs, with Gangplank Galleon and the SMB2 1-1 theme enjoying particularly impressive arrangements. Third party series Mega Man and Castlevania each boast a surprising number of remixed songs, too. And if you're a member of the "everything sounds better with the Guile theme" club, Smash Ultimate has you covered with a cool, synth-filled take there, too.

The Ultimate leak continues a long history of obsessive Nintendo fans discovering Smash Bros. details before they're officially revealed. For those that want to go into the coming game with some sense of surprise, though, treat the next two weeks of Internet surfing as a potential minefield of unintended spoilers.
