If you've been hanging around survival worlds wondering when the next big Minecraft drop is coming — good news. Chaos Cubed is officially next, and it's looking like one of the weirdest, most experimental updates Mojang has done in a while.
Here's everything we know so far, what to expect, and when you'll actually get to play it.
When Is Chaos Cubed Coming Out?
Based on Mojang's current release cadence, Chaos Cubed is expected to drop June 16th 2026. The update will officially be known as version 26.2, since Mojang switched their version numbering earlier this year to be based on calendar year rather than the old 1.21.x system.
The previous drop, Tiny Takeover (26.1), released on March 24th, 2026, and Mojang has been pretty consistent about hitting roughly one drop per quarter. That puts Chaos Cubed somewhere in the back half of June.
What Is Chaos Cubed?
Chaos Cubed is the second of four planned game drops for 2026, and the theme this time around is — well, chaos. The update centers around a brand new underground biome called the Sulfur Caves, plus a genuinely strange new entity called the Sulfur Cube.
If that sounds vague, that's because Mojang has been deliberately mysterious about how this stuff actually works. We've got a rough picture from Minecraft Live and the snapshot releases, but a lot of the details are still being held back. Here's what we do know.

The Sulfur Caves
The Sulfur Caves are a new underground biome located beneath the Overworld surface. They're visually distinct from any cave system currently in the game, with red and yellow blocks giving them a much more vibrant, almost otherworldly look compared to the gray-and-stone aesthetic of regular caves.
Two new blocks generate naturally in this biome, and both can be crafted into a variety of building and brick blocks. So if you've been wanting to build a town that doesn't look like every other gray stone settlement, this update is going to give you a lot of new options.
Sulfur Pools
The biome is dotted with sulfur pools — bodies of water that look perfectly normal but absolutely aren't. Step in one and you'll get hit with a new "noxious" status effect that makes your character dizzy. Mojang hasn't fully detailed how the dizzy effect plays out yet, but it sounds like a screen-distortion or vision-impairment thing rather than direct damage.
The pools come in varying sizes, from small puddles to larger pond-sized features, so navigating Sulfur Caves is going to require some actual care. Just barreling through like you would in a regular cave is going to get you wrecked.
Sulfur Spikes
The new biome also features Sulfur Spikes — spiky versions of the new sulfur blocks that generate naturally and act like stalagmites and stalactites. They form on the floor and ceiling of caves and merge together when placed next to each other, creating cool natural cave formations.
Important to note: they hurt when they fall on you. So watch your head, especially if you're mining around the cave ceilings.
The Sulfur Cube
This is the headline feature of the update, and honestly the most genuinely weird thing Mojang has added to Minecraft in a long time. The Sulfur Cube is a new entity that absorbs other blocks — and depending on what it eats, it behaves differently.
A few examples Mojang has confirmed so far:

What Else Is Coming?
Beyond the Sulfur Caves and Sulfur Cube, Chaos Cubed is going to include a bunch of new building blocks and crafting options derived from the new biome's resources. The full block list hasn't been confirmed yet, but the promotional images suggest builders are going to get a serious palette expansion — particularly if you're into colorful, eye-catching builds.
The Sulfur Cube also seems to be central to a new mini-game-style interaction system. During Minecraft Live, the developers played a series of mini-games featuring the Cube, hinting that it might have applications beyond just being a weird mob. Whether that ends up being a structured game mode or just emergent gameplay from the Cube's mechanics remains to be seen.
Why This Update Matters
Most Minecraft drops over the past year or two have been pretty thematic and contained — Tiny Takeover was about cute baby mobs, Spring to Life was about ambient world detail. Chaos Cubed feels different. It's introducing a genuinely new mechanic (block-eating, behavior-shifting entities) that doesn't really have a precedent in vanilla Minecraft.
If the Sulfur Cube delivers on what's been hinted, this could end up being one of those updates that fundamentally changes how people approach certain situations in the game. Or it could end up being a fun novelty mob that everyone plays with for a week and then forgets about. Either way, it's the most experimental thing Mojang has shipped in a while, and that alone makes it worth paying attention to.
What to Do Before the Update Drops
If you're hyped for Chaos Cubed and want to be ready, here's what we'd suggest:
Stockpile some basics. Wood, ice, slime balls, and other common items are likely going to be Sulfur Cube food, so having a good supply on hand will let you experiment immediately when the update drops.
Mark out an unexplored area. Sulfur Caves will only generate in chunks you haven't explored yet, so if you want to find one in your current world, you'll need to travel somewhere new.
Keep an eye on the snapshots. Mojang releases snapshots for Java Edition before the official update, which is the best way to preview features and figure out what's worth being excited about.
See You in the Sulfur Caves
Chaos Cubed is shaping up to be one of the most interesting drops in recent memory, and there's still plenty we don't know. We'll keep an eye on the snapshots and update this post as more details get confirmed.
In the meantime, finish up whatever you've got going in your survival world — because once those Sulfur Caves drop, a lot of us are going to be heading underground for a while.
