Description

I Survived 100 Days in the lost underground, and now you can too!

This is my latest multiverse adventure, a world of clashing dinosaurs, radioactive abominations, and... Unicorns and Candy?!?! Don't even get me started on the Sculk too... This Caves Only world is a nail biting adventure from beginning to end... and it ends with a BANG.

PLEASE NOTE

Due to the way this world generates (by default with the Lithospherical world type) - certain Alex's Caves structures will not generate. This includes the Primordial Volcano, Candy Cavity witche's tower, and the Abyssal Caves biome entirely. Due to this, some Alex's Caves bosses will be unavailable.

This modpack works entirely on it's own, but to download my specific map from the video, support me on Patreon!

This modpack is as featured in my Hardcore 100 Days video!
