missing.jar (Discontinued)
by Cool modz
Players who want a horror experience in their worlds can install missing.jar, a NeoForge mod by Cool modz for 1.21.1 that adds three entities across one dimension.
What it does
Entities lurk around the world and can appear while the player explores, and the mod also changes time, plays sounds and spawns creatures. It is meant for single-player and multiplayer worlds, and the author describes the new content as added over time. Client and server both run it, so the server and every player need the mod. Files are published for NeoForge only, for 1.21.1, and the mod is discontinued; the latest file is 1.1.1 from 2025-06-11 on the alpha channel. The code is all rights reserved, so it is not open source.
