Description
🔥 Improvised Zombie AI
A dynamic difficulty mod for Minecraft Forge 1.20.1
🧠 What does this mod do?
Improvised Zombie AI makes your Minecraft survival experience more intense by progressively increasing the intelligence and power of hostile mobs as in-game days pass.
As time goes on, zombies and other monsters adapt to the environment, learn new behaviors, and become more dangerous.
⏳ Progression System
| Day | Behavior |
|---|---|
| Day 1–4 | Normal behavior |
| Day 5+ | Hostile mobs begin breaking doors |
| Day 10+ | They gain the ability to break blocks |
| Day 20+ | They start placing blocks and receive combat stat boosts |
All of these behaviors are automatically configured using Enhanced AI, so no manual setup is needed.
