NLLCORE
by Error404ror
NLLCORE, a NeoForge mod for Minecraft 1.21.1 – 1.21.8, adds a surreal dimension of digital anomalies, glitch items and chaotic mechanics.
What it does
Players enter the dimension by building a portal from bedrock blocks. Its biomes mix in unstable ways, so one area can shift into the next without a clear boundary, and the content is built around digital anomaly and glitch aesthetics.
The mod adds anomalous tools and weapons, including the Creatrix, which lets a player change world properties and entity states in creative play. Glitch items and new food types with strong effects are included as well, and some armor sets give unusual interactions. Unique blocks assimilate the structures around them.
Client and server: the server and every player need NLLCORE. Builds are published for NeoForge across eight release versions, and the code is released under All rights reserved, so it is not open source.
