Minecraft’s Overworld is getting ice caves and frozen zombies
The new caves will appear beneath cold biomes, where frozen zombies can drop ice balls or leave players frozen.
TLDR
Minecraft announced that ice caves are coming to the Overworld beneath cold biomes. The studio describes them as ore-rich underground areas with a frozen zombie variant. Defeating those enemies will yield ice balls, while an encounter can also leave the player frozen. The first-party announcement says the feature is “coming soon” but does not give a release date, name a Java or Bedrock preview version, or explain the ice ball and freezing mechanics in more detail.
