Today we reveiw the Underground Biomes Mod -By: Exterminator Jeff
Brief Description by Mod Creator:
I've always thought that there isn't enough variation underground in Minecraft with almost every cave or ravine looking the same. This mod aims to change that by adding 24 new naturally occuring rock types which occur in underground 'biomes' separate to the biomes on the surface. Ore distribution for Coal, Iron, and Gold has been changed to make these occur in larger desposits in certain areas to promote exploration and actual mines.
The rock types added comprise three base categories: Igneous, Metamorphic, and Sedimentary. Igneous and Metamorphic rocks form the base of underground biomes with Sedimentary rocks being found in layers called strata. Igneous and Metamorphic rocks drop their own forms of cobblestone when mined and can also be crafted into bricks. A storage block for coal has also been added as well as a very low quality coal called lignite. Both can be used for smelting.
All recipes from the base game have been incorporated with the new rocks types so for example a lever can be crafted with a stick and a metamorphic cobblestone block. Vanilla cobblestone can also be crafted by placing two rows of two cobblestone blocks. This is to support other mods whose recipes might need regular cobble.
This is the first version of the mod and may contain bugs but I have fixed all the issues that came up during development that I know of. The new ore system could potentially be unbalanced (too easy or too hard) but is quite hard to test. If this is an issue there is a config option to disable the custom ore generation.
In the near future I plan to add half slabs for most of the rock types as well as a system for adding new underground features similar to surface features such as temples and villages. I'm happy to hear any ideas anyone has for featues or anything else.
