Minecraft Snapshot 18w09a

A Minecraft Java Edition snapshot

We're currently battling winter here in the office, but we managed to sneak out this small snapshot a little later than usual.

Changes in 18w09a

  • Added underwater ruins!
  • Added new coral blocks!
  • Phantoms no longer spawn in the end
  • Phantoms despawn in the daytime
  • Optimized particle rendering slightly

Underwater ruins

We've ruined the game. Again.

  • Come in many different shapes and sizes!
  • Cold ruins can be found in cold, frozen, ocean biomes - regardless of depth
  • Warm ruins can be found in warm, lukewarm, and deep lukewarm biomes
  • Can generate alone or in a big ruined village
  • You can also sometimes find them slightly underground or slightly above sealevel
  • They can contain mysterious treasures! So mysterious that we haven't even added the real treasure yet.
  • A few more things to come in a future snapshot...


Pretty blocks! Or should they be mobs? I'm not entirely sure.

  • Comes in 5 colors: blue, pink, purple, red, yellow
  • Requires water to stay alive
  • If it dies, it dies. Sorry.
  • Currently only obtainable in the creative inventory
  • World generation to come in a future snapshot...
