A Leak Just Blew Nintendo’s Cover On A Metroid It Wasn’t Ready To Show

The classification pins production down to 2026 and slaps a 12+ rating on the title in Brazil. That 12+ score sits right between Metroid Dread‘s 10+ and Metroid Prime 4: Beyond‘s 14+. The document flags a reviewed chapter of 41 minutes packed with violence, weapons, blood and death scenes. The provided web link traces back straight to Nintendo of America.

MercurySteam stands out as the most likely candidate to build this new entry. The Spanish studio already delivered Metroid: Samus Returns on 3DS in 2017 and Metroid Dread on Switch in 2021. A cloud hangs over the studio though, following the layoffs announced back in May 2026. YouTuber malo932 claims the team was working on a Super Metroid 2D pixel remake alongside a direct successor to Metroid Dread.

The Ravenous name locks in the 2D theory, since Nintendo reserves the « Prime » label for 3D FPS entries of the franchise. The timing lines up with the franchise’s 40th anniversary in 2026. The original NES Metroid from 1986 reshaped the action-exploration genre. This launch drops in a few months after Metroid Prime 4: Beyond hit shelves on December 4, 2025. The Metroid franchise might just be heading into its densest run since the early 2000s.
