SUHC(Super Ultra Hardcore) is a datapack designed to provide a harder survival experience for the player. The goal is to survive the harsher minecraft world, which progressively scales in difficulty as time passes.

There are many, many tweaks to the difficulty, along with custom mobs, items, loot tables, and many custom structures. SUHC is based around Ultra Hardcore, but there is a lower difficulty for players for whom this is their first experience with anything UHC-related.

SUHC has been in development for quite a long while, and we've done tons of playtesting! Give it a try and give us some feedback!

There is an optional resource pack .zip located in both of the download links, which just contains music for our boss! Music credit is located further down in the post.

(btw if you just want our standalone bossfight, go here: www.planetminecraft.com/project/cadeyrn-the-wretched-boss-fight-multiplayer-compatible/)


  • A unique, challenging boss fight(mini-trailer thing here: www.youtube.com/watch?v=naA3JYDduOY )!
  • Tons of difficulty tweaks(potion rework, mob drop/loot table reworks, mob upgrades, etc).
  • Mob Progression(mobs become stronger over time).
  • 50+ custom crafting recipes.
  • A bunch of custom items.
  • Several custom structures that spawn as you explore the world(such as the graveyard/tree cove/floating island in the gallery).
  • Mobs with custom abilities/effects(Zombies that group up gain the ability to break blocks, creepers can chain explode nearby creepers, etc).
  • Multiple custom loot tables, both for mobs and for structures(including vanilla minecraft structures!).
  • Mini luck rework(luck actually effects loot from some mobs and all chests, and there are new items that grant luck).
  • 34 Random events(mobs may randomly gain temporarily upgrades, major/minor natural disasters may occur, etc).
  • A more challenging survival experience.
  • Nether corruption(coming out of the nether may spread nether around the portal area).

NOTE: One VERY important note - This datapack should only be used in a new world! Using it on a world where you already have stuff will cause mayhem and destroy your beloved stuff!

*Note again: Do this on a newly created world. This datapack is meant to be played on a fresh survival world.

Download the .zip above(kyuandqssuhc.zip), and move it into the datapacks folder that is located in your world file. Then, right click and do 'extract here'. Join the world, type "/reload", and there you go! There's a little important readme that will popup in-game after you type it, it's very important that you read it!
(this is what it should look like in the datapacks folder)

Alternatively, there is also a pre-made ready to play world available to download, just download the zip, put it in your saves file, and do 'extract here'. Then hop into the world, and press the button directly in front of you to begin! The premade world works in 1.17+, if you want one that works in 1.14/1.15/1.16 then check out the Legacy Downloads a bit below.

NOTE: In order to type '/reload' your world/server must have cheats enabled/done by a server op. If you forgot to enable cheats when you created the world, you can open the server in LAN with cheats enabled by going into the world, pressing Esc, and then clicking 'open to LAN' and having cheats enabled in there.
Note 2: If you are on multiplayer, command blocks must be enabled in the server properties.

To change the difficulty, type "/function minecraft:changedifficulty". The difficulty will be toggled, and you will be prompted with a message telling you the difference between the difficulties.

For other settings, such as turning off hardcore mode or grief-y stuff, type "/function minecraft:overridechecksettings"
for the list of settings that can be changed. To change them, type "/function minecraft:override", and the autofill will show you the list of settings that can be changed(entering the command will toggle the setting between on and off):

If you want hardcore mode on but want a certain amount of lives, type "/scoreboard players remove @s KyuDeath 1", with the number being the amount of extra lives that you want.

14 Update Logs

VERSION 1.4.6(10/17/2021) aka the Pumpkin Patch : by Kyu_And_Q 10/17/2021 8:22:49 pmOct 17th, 2021

Some bug fixes and a few spooky things for the spooky season.

VERSION 1.4.6(10/17/2021) aka the Pumpkin Patch:

- Fixed the Nether Corruption not working properly.
- Fixed the BARBIE-KYU random event.
- Fixed the day timer occasionally breaking forever on some worlds.
- Fixed the HELLFIRE! random event.
- Fixed oak leaves dropping oak leaf blocks all the time.
- Fixed the Surprise! gold nugget drop from mobs not working properly.
- The A random event has occurred! text spam now happens less. This does not lower the amount of random events that will occur.

Spooky stuff:
- Regular Skeletons/Zombies now wear spooky pumpkins and carved pumpkins, replacing leather helmets and iron helmets respectively.
- The It's Time to get Spooky! random event now occurs roughly twice as often.
- Added 2 new spooky(also particularly strong) Elite variant mobs, one for Zombies and one for Skeletons.
- Added a new spooky structure, Big Plump. Nothing suspicious about this structure, not at all.

Final Note:
We're stiiiiiiiiiiiiil working on a big upcoming soon(tm(tm(tm))) update. But for now, enjoy the spooky Halloween season, and until next time - Stay fresh, cheesebags.

Is there any report/bug about monsters not spawning?

I used other datapacks with SUHC in realm and also bukkit, but both doesn't spawn monsters.

Monsters spawned very well for early days/nights.(maybe until 30days?)
But, monsters not spawn after!

I think that coming back from nether made some problems.

I'm now testing without other datapacks, only using SUHC.
1. not entering nether for 40days
2. enter nether in 30days and come back after 1hour(real time).

SUHC is so fun, but friends are tired of being no-monsters.

I know you already got your stuff fixed in our discord sever, but in case anyone else sees this. we are not really sure what is causing it, but fixing it we can seem to do if you teleport to 1000000x 90y 1000000z you will get some lag probably, hang out there for a tiny bit just to make sure you see a big bedrock thing with command blocks, then tp back to your old cords and this should fix it.

Should this be compatible with all other world gen datapacks and true survival?

So, I am fairly sure they are compatible, though it is possible some of our stuff may override some of true survival

Will have to look into them, but we have yet to really have any compatibility issues. If you have any specific world gen packs that would help.

Do you plan to update it to 1.17?

Kyu_And_Q avatar
We do, just 1.17 is being rather difficult. Hoping 1.17.1 will be little easier to work with, but if not we will just power through and get the update out

I would like to know if the structures are compatable with biome datapacks, specifiacally

if so, is there any other world gen datapacks you would recommend with this?
