Install Creeper Eater: Ultra Hard #
Install Fabric Loader for 1.21.1 (plus Fabric API if the downloads page asks for it), place the JAR in your mods folder, and launch with the Fabric profile.
- Install the Ultra Hard build for your Minecraft version — files named uhceu-2.1-… (1.21.1 → 1.21.11 published, 26.x experimental).
- Do not mix these files with the standard Creeper Eater jar — they are independent projects.
- Start a world knowing that every mistake may be your last — difficulty is forced to Hard/Hardcore on load.
- Learn what changed: 1.3× wall-tracking chase AI through walls up to 15 blocks, fast devour timers, doubled spawns, cross-dimension and daytime spawning.
- Optional: fine-tune in the JSON5 config — but there is no 'easy'; the curve is single and ruthless.
- Survive — if you can.
Working with Creeper Eater: Ultra Hard #
Product-specific steps, separate from the general install guide above.
Use the uhceu builds
Install the file named **uhceu-2.1-…** for your Minecraft version (1.21.1 → 1.21.11 published, 26.x experimental). Do **not** install this together with the standard Creeper Eater jar — they are independent projects and mixing them breaks the hunt logic.
What you'll see. The mods screen lists the Ultra Hard build under its uhceu name. Difficulty is forced to Hard/Hardcore the moment the mod loads — there is no easy mode.
What is different
Devour replaces the explosion (no block damage), the chase AI tracks through walls up to **15 blocks at 1.3× speed**, difficulty is forced to **Hard/Hardcore**, spawns are **doubled**, and creepers spawn **cross-dimension and during the day**. A dodged devour **fizzles** rather than punishing instantly — but the chase continues.
- Heightened detection — creepers spot you from further away and pursue without mercy.
- Fast devour timers and aggressive spawning tuned for maximum tension.
- Single ruthless curve — fine-tuning lives only in the JSON5 config; there is no 'easy'.
Tips
- Built for players who finished Creeper Eater and asked for more.
- Play hardcore from the start — the mod enforces it anyway, so plan for it.

Tips for Creeper Eater: Ultra Hard #
- Keep Creeper Eater: Ultra Hard on the version range shown on its product page.
- If it doesn't load, confirm the JAR is in the right mods folder for the launcher and version you chose.
- Bedrock Edition, mobile, and console can't run Java Edition mods or packs — for a port or custom variant, request a commission.
