  • Run randomly around the map with no proper AI or movement animation.
  • The first mob to be added into the game.
  • 100 spawn at random positions upon world generation and loading.
  • Does not save into the level.dat file.
    • Once the world is closed and reopened, all mobs previously there would have despawned and new ones would spawn in.
  • Reused from Zombie Town, an abandoned project made by Notch before Minecraft.
  • Are referred to as zombies in the code.


  • This version contains unused functionality that will cause the player to slowly rise up to ground level if they spawn under the world. However, it is not possible to spawn under the world without modding, hence why it is unused.
  • The "rd" before the version number stands for RubyDung, a game Notch was working on before Minecraft, whose codebase was later reused for Minecraft.
  • The oldest publicly known Minecraft world level is for this version.[3][4]
