Minecraft releases Chaos Cubed update with new biome

Minecraft's latest major update, titled "Chaos Cubed," is now available, introducing a new biome, a unique mob, and fresh building materials to the game. The update went live on June 16, 2026, for both the Java and Bedrock editions of the popular sandbox title.

The centerpiece of the update is the Sulfur Cube, a passive mob found in the new underground Sulfur Caves biome. Its defining trait is an ability to absorb blocks, which then alters its physical properties. For example, feeding a Sulfur Cube TNT will make it explosive, while giving it Magma Blocks will make it hotter. Developers have described the mob as a source of endless experimentation, with its speed, bounciness, and other traits changing based on what it consumes.

The Sulfur Caves themselves are a new underground biome filled with yellow Sulfur Blocks and red Cinnabar Blocks, which form two complete new building sets for players. The environment also features hazards like bubbling sulfur pools, which can inflict a Nausea effect, and Geysers that can launch players and mobs into the air. Sharp Sulfur Spikes can also form on cave ceilings and floors, potentially falling and causing damage.
