Underground, non-important biomes are shuffled, providing a semi-random map experience.
There is some occasional graphical issues where some biome backgrounds do not appear around the mines entrance. This will allow you to "see" the map and enemies from afar.. But really you might be thankful for that once you realise what biome awaits you.
This mod should work with other map mods like Noita+ so long as those custom maps are overwriting biome_map.png before Shuffled Biomes is loaded. This mod changes the magic_numbers.xml file to specify biome_map_shuffled.lua as the map to load, which in turn loads "data/biome_imp/biome_map.png" -- which mods can overwrite easily beforehand.
Biomes that are shuffled -
Coal Mines
Collapsed Mines
Twisty Passages
Coal Pits
Fungal Caverns
Snowy Depths
Hiisi Base
Underground Jungle (Layer 1 and Layer 2 are separate biomes)
