NullWorld
by meln_ik
Players who want a psychological horror layer on Forge 1.20.1 can add NullWorld, which puts a persistent entity into survival.
What it does
The entity stalks the player instead of attacking outright. It does not strike; it watches from a distance, and a player can spot it behind trees at the edge of render distance before it vanishes. The constant uncertainty about where it is shapes how the world is explored, even during routine tasks such as mining and building.
Randomized horror events add sudden shifts in the air, unsettling noises and creepy structures that appear at unpredictable moments. Entities use custom animations and AI logic, so encounters differ from vanilla mobs. The mod is intended for survival play, turning the base game into a survival-horror challenge. It is published for Forge only, targeting 1.20.1, with Client and server as the environment: the server and every player need it. The code is under the MIT License, and the mod is not open source. The author notes that the project is in active development, that phases and events are still being expanded, and that some bugs and performance issues remain.

Custom AI entities
