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).
  • Boris
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 1.16/1.16.1/1.16.2+, if you want one that works in 1.14/1.15 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.

Legacy Downloads
These are downloads to older version(s) of premade worlds:
https://www.mediafire.com/file/djcsqm9luy6kas7/Premade_SUHC_World9.zip/file (works in 1.14)

https://www.mediafire.com/file/a5yjay4dk6k5rc5/Premade_SUHC_World10.zip/file (works in 1.15.2)

Credit goes to Mudeth for giving us permission to use his music in this map! You can find him(and the specific track) here: mudeth.bandcamp.com/track/the-hammer-of-pompeii-necropolis

This datapack works with 1.16+, with downloads to older versions that will work in 1.14.4/1.15.2(above). When you do '/reload' you will be given a few notes and a disclaimer - It is VERY important that you read this!!!

12 Update Logs

VERSION 1.4.4(3/27/2021): : 03/27/2021 5:46:51 pmMar 27th

The Tree Cove has returned after being deleted in Version 1.4, with a much-needed revamp.

VERSION 1.4.4(3/27/2021):

Tldr version :

- tree


The Tree Cove has returned to the SUHC world, with a totally different and slightly less ugly look. It also comes with a few probably friendly inhabitants living inside its expansive roots:

- Fletchers who hoard randomly-tipped arrows. They also sell the Alchemical Crossbow, which possesses the ability to launch potions from your inventory. Almost any potion can be fired, with only a few specific custom potions being excluded.
- Farmers who stock their chests with apples, wood, and bonemeal. In order to fund their apple collection, they will sell you Pure Refined Apples, a juicy potion that grants Speed II and Haste I.
- Toolsmiths with an expansive collection of golden hoes, and (for a price) will gladly transform any golden hoes you may have into the Ringo Reaper, an unbreakable golden hoe that has an exceptionally higher chance at reaping apples from leaves.
- Clerics that collect random potion ingredients and have developed the Deliciously Sweet Golden Apple, a type of golden apple that sits between the regular golden apple and the much more powerful enchanted golden apple.
- Librarians which embarrass their fellow villagers with their invention of Pure Refined Paper: Refining Equipment, a magical scroll that will "refine and shine thine tools to mine, with a fine bind of Unbreaking Nine".
- Pillagers and Vindicators that have razed the tree cove and gotten rid of its inhabitants.

The villagers each have custom loot chests relating to their descriptions above, and they scale particularly well with luck.

Misc. fix(es):
- Fixed a bug where the Nether Dungeon would rarely fail to spawn some of its tunnels.

Final Note:
We're currently working on the next major update, which is a revamp of all of our other structures(similar to the revamp of the tree cove in this update!) in addition to a bunch of new structures. We'll most likely have one other small update before then, with a couple of minor additions and some loot table changes.

It should work near as I can tell. As long as the bottom of the world is still bedrock

I replied to you on discord, but I will say again here in case anyone else is wondering. The main 2 download links are in fact for 1.16.2 just if you add it via the in-game datapack manager there is on odd thing where it says it isn't for the current version of the game. ignore that and put it in anyway , because it is actually and will work. To be extra sure in game once you reload you should see at the bottom of the text that shows up in chat "version 1.3.1" this is the latest release of SUHC

Such a cool datapack! Very hard, but I like that. I'm playing with natural healing on though because I can't even get to the nether without dying to invisible creepers and stuff like that lol

"/function minecraft:overridetoggletrackerzombie" will turn off one of them, the other you'll have to go into the functions and disable it manually. The easiest way is to go to datapacks < superuhc < data < zzzzdonotuse < functions < 7sec < main2.mcfunction, and put a '#' at the start of line 24( the line that says "function zzzzdonotuse:7sec/zombiemobment") or just delete line 24 entirely.

Deleting the line 24 does not help.
