Alex's caves prioritizes exploration, creativity and trying to reintroduce a sense of wonder int he player - as if we were playing the game for the first time over again.

The mod is gargantuan, adding six detailed, spectacular and exhilarating cave biomes to the world - gigantic underground pockets of the world. Each one has a distinct theme, with unique aesthetics, osts, inhabitants and resources.

The cave biomes are rare, and require an exploration map and usually a multi thousand block journey to come across. Each biome uses its theme to the fullest, such as magnetic caves including attractive and repulsive tools, armor, pulleys/conveyors and even a gauntlet. The drops are really fun to play around with - and the caves are worth exploring.

From the time I've spent in the mod, its evident a lot of thought, time and effort went into it; effort which isn't wasted since the experience is some of the most fun I've had.

The unique aesthetic is incompatible with most shaders, and I did face some issues with mob spawns and behavior, especially on servers. But when it does work, it is a blast. This is a mod that deserves a place on most, if not all, fantasy/exploration adventurers' modpacks.

Description

Alex's Caves

This mod requires Citadel

Alex’s Caves is a Forge mod for Minecraft 1.20.1 that 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. The mod also has built-in compatibility with Just Enough Items and Alex’s Mobs.

Any additional questions can be answered on the Discord server, and bugs can be reported on Github.
