Spoiler warning: Mario Bros. Wonder has leaked online

Super Mario Bros. Wonder has leaked online, nearly a week ahead of its official release date.

On Friday, images and videos appearing to show previously unseen sections of the game began to be widely shared across social media sites and private Discord channels. It’s claimed that the title is being shared illegally on ROM sites, but VGC has been unable to verify if this is accurate.

At the time of publishing, at least three individuals were even streaming the game on Twitch, showing levels beyond what’s been seen in press previews and Nintendo’s official assets.

Unsurprisingly, those looking to avoid significant spoilers before the game’s October 20 release date may wish to tread carefully on social media for the next few days.

It’s far from the first time a first-party Nintendo Switch game has leaked in this manner. Previously, Pokemon Legends: Arceus and Pokemon Brilliant Diamond and Shining Pearl made it into public hands nearly two weeks before their releases.

Earlier this year, The Legend of Zelda: Tears of the Kingdom also appeared on ROM-sharing sites almost two weeks before its official release.

On Friday, LA-based voice actor Kevin Afghani announced that he’s the new voice of Mario and Luigi in Super Mario Bros. Wonder.

Nintendo announced this summer that Charles Martinet – who has voiced Mario for over 25 years – would be stepping down from the role, but it didn’t announce who had replaced him.

“Incredibly proud to have voiced Mario and Luigi in Super Mario Bros. Wonder,” Afgahni wrote. “Thanks to Nintendo for inviting me into the Flower Kingdom!”

In a video posted by Nintendo last month, Charles Martinet and Mario creator Shigeru Miyamoto discussed Martinet’s new role as ‘Mario Ambassador’.

Martinet said the role will entail “travelling around the world, sharing the joy of the Mario family, and being able to continue meeting with all of you wonderful fans, who I cherish absolutely the most”.
