Minecraft unveils Ice Caves biome at Minecraft Live on the 27th

The Ice Caves use subtle lighting as a core visual idea: softly glowing ice crystals act as the primary light source and can be placed or stood on by players, which makes them useful both as lamps and building blocks. Stalactites grow on cave ceilings and will fall when exposed to strong light, dealing damage on impact; stalactites are also placeable blocks, so torch placement inside these caverns becomes a tactical choice rather than just decoration. A Mojang developer noted the deliberate contrast of lava and ice — not strictly realistic, but chosen because the pairing looked interesting and beautiful in their view.

The biome is intended for mining as well as exploration. Ores will still generate mainly in stone and deepslate, so players moving through ice-block interiors should still find resources in familiar layers, and Mojang plans to add a special ability that makes ice easier to mine. Alongside terrain and tools, the Frozen Zombie arrives as the biome’s signature hostiles: it inflicts a new Freeze status that slows movement and amplifies incoming damage, making encirclement by multiple Frozen Zombies particularly dangerous.

Frozen Zombies can spawn carrying an ice ball which they throw at players; the ice ball’s damage scales with its speed, so a close-range hit can hurt more. Killing a Frozen Zombie carrying an ice ball yields the projectile as an item, which can be used to craft a Freeze Potion that deals a small amount of damage and applies slowing effects—an item Mojang specifically positioned as useful in PvP situations. Mojang says the Ice Caves content will enter testing soon.
