Redstone aficionado Mumbo Jumbo doesn't waste any time jumping straight into the explanation for building this rather unique underground Minecraft bunker, but if you can keep up, it's a pretty amazing guide! He leaps right into a clever entrance-building walkthrough, following up with all the basics for bunker survival - food dispensary, water management, and more besides.
Whether you're looking to build a post-apocalyptic shelter, or just want a home away from prying monster (and player) eyes, this guide is sure to inspire. Enjoy!
