Just got the 1.8 update on Xbox One, and I'm experimenting with the superflat editing options.

If you start to create a new Superflat world, go to advanced Superflat options, and then the Biomes tab, there's a Biome called Extreme Hills. If I create a world with this biome, even using the preset "Tunnelers Dream" which has this biome, there are no hills.

What is the effect of the Extreme Hills biome, if it can be applied to a Superflat?

  • Since the two are opposites of each other, I would say that one cancels out the other. And from what you have described, that is exactly what is happening.

  • Then why would that be an option?

  • And why would they make a preset that uses it?

    It would also affect the spawning of ores; Extreme Hills biomes will have Emerald Ore spawn when decoration is set; other biomes wont. Jul 25, 2015 at 2:18

    @pppery The current stance is that Xbox One version of Minecraft should use the bedrock tag, since that's what users finding this question will be using. I could be wrong, though, so feel free to start a meta discussion if you disagree.

When it means "biome" it really means what color the grass is, leaves, etc. The actual terrain does not get affected, because it is superflat. So extreme hills biome in superflat is basically NOT desert looking grass/leaves/dirt or not swamp looking. An example: enter image description here

See the different colors? That is the difference.

  • snow can also fall at high y-coordinates in extreme hills

Extreme hills biome may cause spruce trees to spawn in a Superflat world.

    Do you think you could go into a little more detail? Generally, one - sentence answers are discouraged, on Arqade. Maybe add information on how Spruce Trees can be more efficiently grown within the environment, what bonuses they give, maybe a picture?
