The leak means that those with ahacked Nintendo Switchand a copy of the dumped game are already playing the plumber’s yet to be released outing.

It is currently unknown, at least to the public, who it was that released the dump forSuper Mario World 3D + Bowser’s Furyto the internet, but the famously litigious Nintendo cannot be happy about the development. The Japanese game giant does have good cause to be upset about the new game being leaked online, however. Not only does this mean that some Switch owners will not be paying for their copy of the Mushroom Kingdom adventure, it also means that those who do wait to purchase the title might have elements spoiled for them as videos and images will surely continue to flood the web over the next few days.

The dump comes fresh off the heels of the first few earlyreviews forSuper Mario World 3D + Bowser’s Furyhitting the web. So far, according to critics, the expanded Switch port is a worthy addition to theMariolibrary and is receiving the praise and high review scores gamers have come to expect from a flagship Nintendo property. Whether or not Nintendo is aware of who released the dump of the game, if history is anything to go by, it will likely be coming after the person or people responsible with the full force of the law.

The company has previously sued and shut down websites that share roms of old Nintendo and Super Nintendo games, and a few years ago Nintendo’s Pokemon Company sued the parties responsible for thePokemon Sword and Shieldleaks. As theBowser’s Furyleak combines the two aforementioned crimes, history will probably repeat itself in this instance.

Of course, Nintendo has also been on the receiving end of several lawsuits in the last few years, most involvingJoy-Con drift on Switch controllers. Lawsuits aside, the company has had a strong few years. The Switch is selling in numbers that rival the original Wii, and longtime franchises likeThe Legend of Zeldaare as popular as ever. Still, theBowser’s Furydump has to be a frustrating blow a mere week away from release.
