ExtremeCore - The Ultimate Minecraft Hardcore Experience
Tired of the usual Hardcore?
ExtremeCore gives you a chance to experience true difficulty and feel what it's like to be completely helpless. This mod completely overhauls survival, turning the familiar world into a hyper-aggressive environment where every single mechanic works against you.
Core Features & Brutal Changes:
- You begin your journey with only 3 hearts and 5 hunger points. To make things even more stressful, your hunger bar is completely invisible, and natural health regeneration is disabled (hearts can only be restored using potions or golden apples).
- Zombies have learned to break blocks if they know you are hiding behind them, and they apply "Slowness II" when standing near you.
- Skeletons now have +200% HP, an increased follow range, and apply "Weakness I".
- Endermen get angry even if you just look near them, paralyzing you for a short time if they catch your gaze.
- Creepers are always charged. Drowned have a 100% chance to spawn with a trident. Bats have become untouchable killing machines dealing 1 HP of damage, and even dolphins have turned hostile.
- Mobs completely ignore boats and minecarts.
World & Resource Scarcity:
- Days are now three times shorter. Your underwater air bubbles are reduced to just 5.
- Ghast fireballs can no longer be deflected.
- Iron Golems no longer drop iron, Villagers refuse to trade, and chests inside structures are either entirely empty or completely stripped of useful loot.
Dimensions Reimagined:
- Piglins will no longer spare you just because you're wearing gold. If you try to barter or offer it to them, they will simply ignore you and continue the hunt.
- As for The End... Don't worry about it.
Important Information:
Make sure to enable vanilla Hardcore mode, otherwise the mod's features won't trigger.
