HJs Chaos Mod (AKA The Chaos Expansion) is a mod full of random ideas and memes. It adds a whole list of ores, armor, items and blocks.
The Mod is able to be used in creative AND survival as most of the items have crafting recipes.

The Chaos Mod currently only has 1.16.5 support but that is planned on being changed later.
New Ideas are being added semi-frequently and new mod versions will be released soon.

A full list of crafting recipes will be uploaded soon

Some Major Additions:

Many New Biomes
2 New Dimensions
New Weapons (Melee and Ranged)
New Ore Set
2 New Mobs
An Orbital Strike

Overview

The HJs Chaos Mod (or just 'Chaos Mod') is a mod focusing on adding more things to do and explore in the progression of the game, via new mobs, biomes, and dimensions. Most of this mod is centered around various meme items, however this mod began production 3 years ago, so much of the content is now dated (and unfunny).

Features

The Chaos Mod has many features that can be enjoyed by both survival and creative mode players.

Biomes

Explore the new variety of biomes, such as the Joe Biome, Joe Hills, Chaos Ruins, and Depleted Chaos Biome, each with their own special generation and structures, as well as mobs.

Mobs

Fight the AmogUs hordes that spawn at night, and beware the mysterious entity that can be seen lurking in the darkness.

Dimensions

Explore the dangerous joe dimension, or if you afford it, build a portal to the Chaos Dimension, where nothing is as it seems...

Ores and Armor

Using the new materials found throughout the Chaos Mod, craft powerful armors, each with special effects!

Weapons

Craft a variety of weapons, some being overpowered, and others being... not so much.

Creative Mode

Admin Tools (W.I.P)

The Chaos Mod features some admin tools and items, such as admin weapons and orbital strike launchers.

Commands (W.I.P)

Want to give yourself exactly 690 amogus items? Theres a command for that!

Update Plans

Forward Ports

The Chaos Mod currently only supports 1.16.5. However, a 1.20.1, 1.21, and 1.21.7-8 version is in the works. However, due to large changes between updates (specifically with how biomes generate), not all features will work exactly the same. Once the 1.20.1+ port is stable, production will stop on the 1.16.5 branch.

New Content?

Progress is slow with the mod, but a new content update is being worked on and should arrive alongside the second version of the 1.20.1 port.

TLDR

Update 2.2.2 (Current Version) will be updated to 1.20.1, Update 2.3 (next content update) and all future updates will only be on 1.20.1 and above.
