Mojang has dropped the second major Minecraft update of 2026, and it’s a big one. Chaos Cubed officially launched on June 16, 2026 as Java Edition 26.2 and Bedrock Edition 26.30, and it’s available right now across PC, console, and mobile. First announced at Minecraft Live back in March, the update introduces a brand new underground biome, the most mechanically interesting mob Minecraft has had in years, two full new block sets, geysers, new music, and a handful of changes that even veteran players won’t see coming. Here’s a complete breakdown of everything that’s new.
The Sulfur Cube — The Star of the Show
The sulfur cube is the mob that’s going to have everyone talking. Found naturally in the new sulfur caves biome, it’s a passive, slime-like creature — it moves by hopping around, splits into two smaller cubes when killed, and can be scooped up with a regular bucket to transport back to your base. Small sulfur cubes can even be fed slimeballs to grow into full-sized ones, which is a neat little mechanic for anyone who wants to breed them.
What makes the sulfur cube unlike anything else in Minecraft is its core mechanic: it absorbs blocks. Drop a block near one or use a block directly on it, and the cube sucks it up, locks in place, and gains entirely different behavior depending on what it ate. Some examples of what happens:
- Wood block: The cube becomes bouncy and fast, pinging around like a rubber ball.
- Wool block: It becomes light and slow.
- Packed ice: Turns it into a sliding puck with minimal friction.
- Magma block: Gives it a “hot” archetype — it damages nearby players and mobs, essentially turning it into a mobile hazard.
- TNT: It becomes a live explosive that retains its mobility. Ignite it and something chaotic is going to happen. This also unlocks the new “Uh-oh.” Husbandry advancement.
You can remove the block from an absorbed sulfur cube by using shears on it, which resets it back to its normal state. The mob follows players holding blocks it can absorb, which means luring and experimenting with them is genuinely fun. Mojang has positioned the sulfur cube as a tool for minigames, contraptions, and Redstone builds — the kind of mob that the creative community is going to run wild with.
Sulfur Caves — A New Underground Biome Worth Exploring
Sulfur caves are the home biome of the sulfur cube and the heart of the Chaos Cubed update. To find one, look for sulfur pools or springs on the surface of the Overworld — the distinctive yellow and red coloring of sulfur and cinnabar blocks visible at the surface, along with noxious gas bubbling up, is your signal that a sulfur cave system sits below. Dig down and you’ll hit the cave biome.
Inside, the environment is visually striking. Yellow sulfur blocks and deep red cinnabar blocks line the walls, with sulfur spikes growing from the floors and ceilings similar in appearance to dripstone. Stepping on sulfur spikes is harmless unlike pointed dripstone, but they can fall and deal damage — it’s rare, but worth watching out for.
The most dangerous element of the biome is the sulfur pools. These bodies of water contain potent sulfur at the bottom, which generates noxious gas that spreads across adjacent water up to three blocks in radius. Any player or mob that enters noxious gas-affected water gets hit with the Nausea status effect. Navigating these pools requires attention, especially when you’re also trying to manage sulfur cubes nearby.
One other major change tied to the sulfur caves: cave spiders now spawn naturally in the biome, taking the place of regular spiders. This is the first time cave spiders have ever generated in the wild — previously, they only appeared from monster spawners inside abandoned mineshafts and trial spawners. It adds a genuine edge of danger to the new biome, since cave spiders are venomous, faster than regular spiders, and have a small enough hitbox to be genuinely annoying to deal with.
Geysers — A New Surface Feature
Geysers are a new environmental feature that connect the underground sulfur cave systems to the surface. They form when a potent sulfur block sits on top of a magma block and under one to four water source blocks, creating a high-pressure water column that launches players upward. You can build geysers yourself with the right materials, making them a functional vertical boost mechanic for creative builds or an interesting landscaping element. Geysers on the surface are also one of the easiest ways to identify where a sulfur cave is hiding below.
Two New Block Sets — Cinnabar and Sulfur
Builders are getting two complete new palettes with this update. Both cinnabar and sulfur come with their full block sets — stairs, slabs, walls, polished variants, bricks, brick stairs, brick slabs, brick walls, and chiseled versions. Cinnabar brings a rich, dark red tone to builds, while sulfur adds a vibrant yellow — a combination that opens up color options that Minecraft builds have never had cleanly before. Both can only be mined with a pickaxe, standard for stone-type blocks.
New Music — Composer fingerspit Joins Minecraft
The Chaos Cubed update also brings a significant music expansion. Composer fingerspit (Paula Ruiz) is the newest addition to Minecraft’s music roster, contributing multiple new tracks to the game. The headlining addition is the “Bounce” music disc, which can be found inside minecart chests in abandoned mineshafts located within sulfur caves — so hunting it down will take some exploration.
Beyond the disc, five new ambient tracks — Ebb, Home, Memories, Nightly, and Shores — have been added to the main menu music, Creative Mode music, and a wide range of biomes. The full list of biomes getting the new ambient tracks includes:
- Mesa, Bamboo Jungle, Cherry Grove, Desert, Dripstone Caves
- Flower Forest, Forest, Frozen Peaks, Grove, Jagged Peaks
- Jungle, Lush Caves, Meadow, Old Growth Spruce Taiga, Old Growth Pine Taiga
- Snowy Slopes, Snowy Peaks, Sparse Jungle, Swamp, Sulfur Caves
Technical Changes — Vulkan Support and Friends List
On the technical side, Java Edition 26.2 introduces an experimental Vulkan 1.2 renderer, which is a significant backend shift for PC players. Vulkan support is experimental for now, so don’t expect it to replace the existing renderer immediately, but it’s a clear signal of where Java Edition’s graphics pipeline is heading. Bedrock Edition also gains a new unified Friends List UI, making multiplayer connectivity cleaner across platforms.
A few other quality of life fixes round out the patch: volumetric fog now key frames with the time of day, the End dimension gets boss fog while the ender dragon is alive, and a variety of rendering fixes for Vibrant Visuals were addressed.
Where Chaos Cubed Fits in the 2026 Minecraft Roadmap
Chaos Cubed is the second of three planned major updates for Minecraft in 2026. The year started with the Tiny Takeover update (Java 26.1, released March 24), which flooded the game with new baby mobs and introduced the golden dandelion item that stops baby mobs from growing up — a surprisingly divisive addition that had the community debating mob farm mechanics for weeks.
The third and final drop of 2026 is the Dappled Forest update, arriving this fall. Based on what’s been teased, it will introduce autumn-styled forest biomes packed with orange, red, and yellow flora, along with new wood types to go with them. If you’re a builder or just someone who enjoys the atmosphere of Minecraft’s world, that one is shaping up to be worth the wait.
Minecraft also made waves recently at a Nintendo Direct with the announcement of an official Nintendo Switch 2 port featuring advanced lighting, volumetric fog, and a stable 60 frames per second — though no specific release date has been set yet. For a game approaching its sixteenth year, the pace at which Mojang keeps adding genuinely new systems and biomes is honestly impressive.
If you’re also keeping tabs on what else is going on in gaming right now, EA Sports FC 26 just landed on Xbox Game Pass with free World Cup DLC included, and over in the GTA world, GTA 6 preorders go live June 25 with analysts projecting record-shattering day-one sales. On the Pokemon side, don’t miss the Pokemon Pokopia Wish Upon a Jirachi event running June 23 through July 8.
