corrupted_worlds.jar [Horror]
by Artmsrd
With corrupted_worlds.jar, the Overworld and other dimensions gain unsettling spaces, entities and random events built around a horror theme on Forge for 1.20.1.
What it does
The mod spreads its horror content across 15 dimensions, 11 entities, 9 random events and 9 structures that spawn in the Overworld, so a player can meet strange places and creatures during ordinary play. A small set of random events can also appear at any time, which makes the world feel less stable than vanilla terrain.
Some features reach outside the game window. The mod can take screenshots and save them to the desktop, and it can change game settings such as render distance. Its sounds are loud, so players may want to adjust their volume before playing. Because the mod is still in development, some dimensions look incomplete and parts may be buggy.
Corrupted Worlds targets only Forge 1.20.1. It runs on the client and the server together, so the server and every player need it, and it is released under the MIT License without being open source.
Key features
Fifteen dimensions
Fifteen dimensions are added to the game, each with its own terrain and atmosphere, and some are still incomplete.
Eleven entities
Eleven new creatures and mobs appear in the world, set up for the horror theme of the mod.
Nine random events
Nine events can happen unexpectedly during play, changing the surroundings or the mood of the world.
Nine Overworld structures
Nine structures generate in the Overworld, so explorers can find the horror content without leaving the main world.

What the author says
A small horror mod that adds scary (maybe) liminal dimensions into your minecraft world. It was inspired by SixAlphaSix.jar and Wonderland.jar. (But that doesn't mean I stole the content from there.) This mod adds: - 15 dimensions - 11 entities - 9 random events - 9 structures that spawn in Overworld
