Echoes of the Void Mod brings the Upside Down dimension and dark threats into your Minecraft world. Your game starts out normally until you trigger an event called The Awakening. Once active, dangerous monsters like the Demogorgon and Vecna stalk your world through dark rifts. You can unlock psychic powers to lift enemies, tear open portals in reality, and use music to escape deadly curses.
