Minecraft launches Chaos Cubed update with Sulfur Cubes

Mojang released the Chaos Cubed update (Bedrock Edition 26.30) this week. The patch adds a new underground biome called Sulfur caves, a block-eating mob called the Sulfur Cube, new building blocks and a range of technical and gameplay fixes across platforms.

The Sulfur Cube is a new mob that appears in Sulfur caves and absorbs blocks it encounters. The patch notes say the cube’s physical properties change depending on the block it has absorbed, affecting its speed, bounciness and other behaviors. Players can capture a Sulfur Cube with a new Bucket of Sulfur Cube item. Feeding the creature special blocks produces distinct effects: giving it TNT can create explosive outcomes when ignited and feeding it Magma produces a hazardous “hot potato” interaction.

Sulfur caves form beneath Sulfur springs on the Overworld surface and include shallow pools, glow lichen and yellow Sulfur and red Cinnabar blocks. The update adds full block sets for Sulfur and Cinnabar that players can use for building. Geysers appear where a Magma block sits under potent Sulfur submerged beneath water; they can launch players upward and may apply a Nausea effect. Sulfur spikes grow on Sulfur and Cinnabar blocks, resemble stalactites and stalagmites, and can fall occasionally and cause damage.

The update also adds music and audio content. Composer Paula Ruiz, known in-game as fingerspit, contributed new tracks and a music disc titled “Bounce,” which can be found in minecarts with chests in abandoned mineshafts inside Sulfur caves. New menu and biome tracks were added to several areas of the game.

Several visual and performance changes are included. Texture streaming is enabled by default on supported PC and mobile devices, with an option to disable it in video settings. The patch fixes multiple Vibrant Visuals and ray-tracing issues, updates fog and volumetric effects for several biomes, and resolves rendering and animation problems on specific platforms.

Chaos Cubed includes many accessibility and quality-of-life updates. The Video settings list now contains a Panorama Scroll Speed slider for the main menu background, text-to-speech reads the ampersand as “and,” and text fields and UI navigation behavior have been improved. Gameplay fixes address mob behavior, item duplication, loot tables and vehicle movement. Realms and Realms Hub received updates to settings and save handling, and Windows players can access an early preview of cloud backup for worlds with increased preview storage capacity.

Mojang published the full 26.30 changelog and asked players to submit feedback at feedback.minecraft.net and report bugs at bugs.mojang.com. The Chaos Cubed update arrives ahead of Minecraft’s planned release on Nintendo’s Switch 2 later this year, where the game will support Vibrant Visuals enhancements, improved lighting and shadow effects, and the ability to carry over existing Switch worlds to the new hardware.
