Metroid fans have had a rough year. Prime 4: Beyond finally landed after nearly a decade in development, and it split the fanbase right down the middle. Now, less than seven months later, a ratings board leak out of Brazil has surfaced a title nobody was expecting: Metroid Ravenous.

No trailer. No announcement. Just a filing that appeared, then vanished, and a screenshot that’s now doing the rounds on every Nintendo forum. So let’s break down exactly what we know, why this matters so much for the series right now, and why a return to 2D might be exactly what Metroid needs.

WHAT WE ACTUALLY KNOW

Let’s start with the facts, because there aren’t many of them.

On June 30th 2026, a listing appeared on the site of Brazil’s Ministry of Justice and Public Security. It referenced a game called Metroid Ravenous, filed by Nintendo of America, with 2026 listed as the year of production and the United States listed as the country of origin. The rating itself was 12+, based on a review of around 41 minutes of submitted material, flagged for violence involving weapons, blood and death, along with light sexual content.

That listing was pulled almost immediately. But not before it was screenshotted and shared, first by a user called Necrolipe, then picked up across the usual outlets — Nintendo Life, IGN, GoNintendo, and My Nintendo News among them.

That’s genuinely it. We don’t have a platform confirmed, though a 2026 Brazilian ratings filing from Nintendo of America all but guarantees Switch 2. We don’t have a genre confirmed. We don’t have gameplay, screenshots, or a release window beyond “sometime this year.”

What we do have is context, and context is doing a lot of heavy lifting here. This wouldn’t be the first rumour of a new Metroid. There have been earlier claims, including a YouTube leak pointing to both a numbered Metroid 6 and a Super Metroid remake in development for Switch 2. And on the day the rating surfaced, VGC’s Andy Robinson added fuel to the fire, saying more than one new Metroid project is currently in development at Nintendo, though he stopped short of giving specifics.

Put that together, and you get a plausible picture: Ravenous isn’t a one-off. It might be the first confirmation of a broader Metroid push on Switch 2, arriving at a moment when the series desperately needs some good news.

A HIGH BAR THAT’S HARD TO CLEAR

To understand why this leak has fans losing their minds, you need to understand what Metroid Dread actually did for this franchise back in 2021.

Dread wasn’t just a good Metroid game. It became the best-selling entry in the franchise’s history, eventually surpassing 3 million copies and overtaking Metroid Prime’s long-standing record of 2.84 million, which had stood since 2002. Developed by MercurySteam, it was the fastest-selling and most successful 2D Metroid ever made, and it did it by going back to basics: tight side-scrolling exploration, a genuinely threatening antagonist in the E.M.M.I. robots, and a story that finally paid off decades of lore.

Dread proved something Nintendo had struggled to prove for years: a modern, classically-styled 2D Metroid could be both critically adored and commercially viable. It gave the series momentum it hadn’t had in a generation.

Which makes what happened next all the more frustrating.

THE PRIME 4 PROBLEM

Metroid Prime 4: Beyond was finally released in December 2025 after a development saga that began in 2017 with Bandai Namco, was scrapped, and was restarted at Retro Studios in 2019. Eight years later, it arrived as one of the most anticipated Switch 2 exclusives of the year.

And the reception was, to put it plainly, rough.

The technical side landed. Reviewers consistently praised it as a genuine showcase for Switch 2 hardware, with stunning environments and rock-solid performance across both graphics modes. But almost every major review flagged the same core problems. The open-world structure felt padded rather than purposeful, with a barren central hub connecting the game’s areas. Abilities felt recycled under new names — the Psychic Boost Ball, the Psychic Spider Ball — rather than genuinely new tools. And the escort-mission dynamic with the Federation NPCs, whose deaths trigger a game over, turned exploration into babysitting for long stretches.

Multiple outlets went as far as to call it the most disappointing Switch 2 release of 2025. Not the worst game on the system, but the one that fell furthest short of expectations, given the pedigree of the studio and the weight of the Metroid Prime name.

That gap between hype and delivery matters here because it’s the exact backdrop against which Metroid Ravenous is emerging. Fans aren’t just excited about a new Metroid. They’re anxious for one that actually delivers.

WHO’S ACTUALLY MAKING THIS?

This is where the community is split, and honestly, both arguments hold up.

The case for MercurySteam: they’re the studio behind Dread, this era’s clearest Metroid success story. A numbered mainline entry with a name like Ravenous fits their established rhythm, and a side-scrolling Metroid is a significantly shorter, less resource-intensive project than another Prime-scale open-world game. If Nintendo wants a win on the board quickly after Prime 4’s mixed reception, MercurySteam building on the Dread formula is the fastest, safest route there.

The case against Retro Studios doing this one: they just spent the better part of a decade on Prime 4: Beyond. It’s hard to imagine that team pivoting straight into another full Metroid project without a break, especially with reports that Retro is already attached to a separate, unrelated project.

Nothing here is confirmed. Nintendo hasn’t credited a developer, and until they do, this is informed speculation, not fact. But if you’re betting on who’s steering Metroid Ravenous, MercurySteam is the shorter price.

THE REDEMPTION ARC

Here’s the honest read on why this leak is such a big deal.

If Metroid Ravenous is what a chunk of the fanbase is hoping for — a 2D, Dread-style entry, possibly the sixth mainline numbered game, continuing directly from Samus’s story after Raven Beak — it’s arguably the single fastest way for Nintendo to repair goodwill after Prime 4. Not because 2D is inherently better than 3D, but because it’s the format that’s already proven it can deliver both critically and commercially in this franchise’s era. Nintendo doesn’t need to reinvent Metroid right now. It needs to remind people why Dread worked in the first place and build from there.

There’s also a scheduling argument worth mentioning. Community chatter has already pointed out that Switch 2’s back half of the year is looking a little thin beyond Fortune’s Weave in September and the Ocarina of Time remake. A 2D Metroid slotting into an October or November release window, echoing Dread’s own October 2021 launch, would make a lot of sense from a release-calendar perspective, too.

None of that guarantees quality. Dread was excellent because MercurySteam nailed the fundamentals, not just because it was 2D. But the format gives this project a much clearer, lower-risk path to being genuinely good than Prime 4’s ambitious open-world experiment ever had.

THE VERDICT

So where does that leave us? We have a real, government-filed rating for a game called Metroid Ravenous, quickly deleted, pointing to a 2026 release. A franchise insider suggests that more than one new Metroid project is in motion. And we have a fanbase still processing a Prime 4 release that didn’t live up to eight years of anticipation.

Everything about the developer, the genre, and the platform remains speculation until Nintendo says otherwise. But if the timing, the rating content, and the community’s own leaked information from earlier in the year line up the way they appear to, Metroid Ravenous looks like the series’ best shot yet at recapturing what made Dread special.

We’ll be tracking this one closely. If there’s a Nintendo Direct or a Nintendo Today reveal on the horizon, expect a follow-up the moment anything official drops.
