Flat Bedrock Layer is a mod that causes the Bedrock layer on the bottom and top of the world(s) to only form one layer, as opposed to random heights of Bedrock across the bottom and (for The Nether), top five layers.

This mod does not rely on either ModLoader or Minecraft Forge, and installs directly into MINECRAFT.JAR. An option is available for those running Minecraft Forge, to ensure full compatibility.
