Description

THIS MOD REQUIRES GeckoLib TO WORK!

Want to immerse yourself in a very suspicious world? You'll see the strangest and most terrifying dimensions, and you'll have to escape from them!

Try to avoid entities that want you dead. Try to save your world! Otherwise, you'll lose access to it. This is a psychological meta-horror mod. You don't just survive in the game—the game interacts with you.

  • Features:
  • Terrifying Dimensions: You will travel through glitched, liminal levels (Level 2 to Level 6) featuring endless mazes, strange libraries, and the creepy "Worldbrick". Custom Entities: Avoid monsters that hunt you in different ways. You will meet LostSteve, the Skinstealer, the 2D black void called Nothing, and the demon steve (who aggressively breaks blocks to get to you and shows exactly how many blocks away he is on your screen). Chat Puzzles: You will need to figure out specific passwords and type them into the Minecraft chat to open doors and survive.

⚠️ Warning:

  • Be prepared for something to possess your computer. This mod features screamers and loud sounds. But more importantly, here is what the mod will ACTUALLY do to your PC:
  1. Create .txt files: It will drop text files with clues and binary codes directly onto your real-life Desktop.
  2. System Pop-ups: It will create custom Windows error pop-ups (dialog windows) outside of the game.
  3. DELETE YOUR WORLD: If the "brokengod" entity kills you, the mod will crash your connection and permanently delete your world save (level.dat). Do not play this on your main survival world!

Note for Multiplayer: You can play this with friends! To protect servers, the world-deletion feature automatically disables itself in multiplayer. Also, the real-life .txt files will only appear on the Server Host's computer.

This horror mod was inspired by The Broken Script and wonderland.jar so that it too could do something terrible.
