An unofficial Fabric port of 'Alex's Caves' - Explore five new rare cave biomes hidden under the surface of the Overworld...
⬇ Download on Modrinth






Alex’s Caves adds 6 new cave biomes to the Overworld. Unlike most normal biomes, these cave biomes are exceedingly rare - yet they all contain a variety of unique blocks, items, mobs and mechanics that makes them considerable subterranean destinations. These six biomes are the Magnetic Caves, the Primordial Caves, the Toxic Caves, the Abyssal Chasm, the Forlorn Hollows and the Candy Cavity.
To find any of these cave biomes, you’ll need to discover an Underground Cabin anywhere in the overworld. From there, you will find loot barrels with cave tablets and a Cave Compendium - a guide book for Alex’s Caves that should provide you with all the knowledge needed to find and explore any biome added by the mod. For more information on getting started, see the 'Getting Started' section on the mod’s wiki.
Alex’s Caves is a very large mod with a great deal of effort put into the look and feel of each new biome. Each biome added may have its own ambient particles, fog, brightness, light color and more. Because of this, it is recommended to experience this mod without shaders, since many shaders can alter or worsen the unique appearance of several of the biomes. However, if you want to - Iris shaders and voxy work well with this mod.
This is an unofficial Fabric port of Alex's Caves. Please do not contact the original mod authors or submit bug reports to their official trackers for any issues encountered while playing this version.
This port is still in active development, so expect bugs. If you find any missing features, bugs, crashes or something that has not been properly ported, just open an issue on the dedicated GitHub repository: q4diffuse/AlexsCavesFabric so i can fix it. Ty! :)
