Minecraft's Chaos Cubed update will release as Java Edition 26.2 and Bedrock Edition 26.30 during the second quarter of 2026, introducing a fundamentally different approach to cave exploration. The new cave biome, the Sulfur Caves, will shake up the caving experience as we know it, moving beyond the standard water pools and lava flows players have encountered for over a decade.
The headline feature of the biome is its hazardous environment. The sulfur caves might look warm and inviting, but the pools are downright noxious and cause a strange dizzying effect if you get too close. The visual design is equally striking. Two new block sets are being added as part of this biome: cinnabar and sulfur, with bright reds and yellows shaking up the regular grey stone we are so used to seeing.
The biome is home to a new passive slime-like mob called the Sulfur Cube, immune to fall damage, which will split into two small cubes when killed and can then grow back up to regular size like other slime-based mobs. The mob has capabilities unlike anything else in the game. The Sulfur Cube has the ability to absorb different types of blocks that can directly affect its behaviour and movement; if a Sulfur Cube absorbs a wood block, it behaves like a bouncing cube, whereas if it absorbs ice, the cube slides around like butter.
Game director Agnes Larsson told developers that the Sulfur Caves are truly embracing the sandbox-ness of Minecraft. Gameplay tech lead Marco Ballabio suggested the mob's mechanics could unlock new types of player creations. The block-absorption system is designed to empower players rather than impose a single intended use. Instead of creating a specific experience, Mojang tries to enable and inspire players to create their own experiences.
Beyond the game update, Minecraft World, opening in 2027 at Chessington World of Adventures in Greater London, is a £50 million project that represents the next major evolution of the franchise. The land will include new attractions including a world-first Minecraft coaster, themed retail and dining, plus a host of fan favourites and ridiculous fun from the Minecraft universe.
Just a 35-minute direct train from London Waterloo, Minecraft World will open at Chessington World of Adventures in 2027. The partnership extends collaboration with a selection of iconic Minecraft creators to help bring the universe to life in the most authentic way possible for the game's global community of fans. Senior Creative Director of Entertainment Torfi Frans Ólafsson said Minecraft World represents a meaningful milestone in the journey to expand the Minecraft universe, adding that the team at Merlin Entertainments and Mojang have worked hard to craft an experience that feels immersive, authentic and welcoming.
The announcements reflect Mojang's shift away from annual massive updates towards smaller releases throughout the year. Both the game update and the real-world attraction aim to expand what Minecraft means beyond the screen, giving players and fans new ways to experience the world of blocks, mobs, and creative possibility.
