not_found.jar
by Milkk_
not_found.jar, a NeoForge mod by Milkk_, adds a cursed horror-themed adventure with entities to interact with, five dimensions to explore and randomly spawning structures.
What it does
Players meet around ten entities that they can interact with, and the world holds thirteen randomly spawning structures to come across while exploring. Five dimensions are available to explore, and more than fifteen random events can happen during play, so two sessions rarely unfold the same way.
The mod is built for single-player and for multiplayer servers, since the server and every player must run it. Files are published for NeoForge only, on 1.21.8, with version 1.1.3 as the latest file from 2026-08-16. The mod was first published on 2026-02-09 and the license is All rights reserved, so it is not open source.
Key features
Interactive entities
Around ten entities respond to the player, turning encounters into interactions rather than simple fights.
Five explorable dimensions
Five dimensions add separate places to travel to, each with its own layout and atmosphere to discover.
Random structures
Thirteen structure types spawn at random across the world, so their locations change from one world to the next.
Random events
More than fifteen random events can occur during play, adding unexpected moments to exploration.
