# Lethal Breed - Predator Evolution

> [!IMPORTANT] > **This mod is currently in active beta testing.** Minor bugs may occur. Your feedback is essential to refining the AI! --- > "Zombies are no longer brainless meat sacks. They are now intelligent, adaptive, and relentless hunters." --- ## Overview **Lethal Breed** is a total overhaul of zombie AI for Minecraft Fabric 1.21.11. Forget passive monsters waiting to be hit. Our zombies use a complex **Finite State Machine (FSM)** to analyze their environment, track prey by sound, and overcome any obstacle — whether by mining through your walls or building makeshift bridges. --- ## Capabilities ![Capabilities](https://img.shields.io/badge/Advanced-Capabilities-darkgreen?style=flat-square)

Mechanics

### Dynamic Hearing Zombies no longer just see you. They **hear** you. * **Sound Reaction:** Footsteps, broken blocks, or explosions attract their attention. * **Persistent Tracking:** Once a sound is localized, they will investigate the area even if they lose visual contact. ### Swarm Engineering No base is safe. Zombies adapt dynamically to the terrain: * **Bridging:** If faced with a gap, they will place **dirt** blocks to cross. * **Scaffolding:** They can stack up and place **dirt** under their feet to climb. * **Tactical Mining:** They analyze obstructions and dig intelligent tunnels towards you. * **Crawling Adults:** Baby zombies are gone. Instead, you will face adults capable of crawling through 1-block high gaps. ### Behavioral States Each zombie follows a logic of survival and tracking: * **Chase:** Aggressive pursuit and agile climbing. * **Distress Call:** A wounded zombie will scream, sending its exact position to all allies within a 12-block radius. They will converge to form a punishing swarm. * **Looting:** Every zombie can pick up and use your equipment. Dying to them often means they will wear your own armor against you. ### Performance Lethal Breed offloads heavy calculations (block scans, building AI) to separate threads. Hundreds of intelligent zombies can coexist without impacting the server's TPS.

Details

### Variability The statistics system makes every individual unique and unpredictable: * **Scale/Power Correlation:** A zombie's size (Scale) directly multiplies its **Max Health** and **Attack Damage**. * **Variable Agility:** Smaller specimens are often faster, compensating for their fragility with frantic speed. ### The Mutant There is a 5% chance (configurable) for a zombie to become a **Mutant**. * **Dark Aura:** Recognizable by its squid ink particle aura. * **Final Breath:** Upon death, the Mutant explodes, releasing a swarm of minions to avenge its fall. * **Boosted Stats:** Larger, stronger, and much more resistant. ### The Kamikaze Some zombies carry an unstable explosive charge (recognizable by the **TNT** block on their head). * **Scalable Detonation:** Explosion power depends on the zombie's size. * **Visual Warning:** Electric sparks and flames appear just before the explosion. Run.
