Zombie Horde

Zombie Horde turns vanilla zombies into a scalable siege system for Fabric.

Zombies do not simply run toward the player anymore. Depending on the selected settings and progression, they can break blocks, place blocks, build stairs, create bridges, sprint, jump across gaps, and use different combat roles to keep survival challenging over long play sessions.

Core Gameplay Features

• Block Breaking AI
  Zombies can destroy valid obstacles to open paths toward players.

• Block Placing AI (Hardmode)
  Builder zombies can place blocks to create vertical routes, overcome obstacles, and apply pressure to defensive structures.

• Bridging Behavior
  When no direct route exists, zombies can place blocks to bridge gaps and continue advancing.

• Stair Building
  Zombies can build stairs to reach elevated areas and overcome height differences.

• Sprinting and Gap Jumping
  Zombies can sprint while pursuing players and jump across small gaps.

• Special Zombie Variants
  Multiple variants with different combat profiles are available, including Normal, Tool, Brute, Scout, and Trapper zombies.

• Role-Based Pressure
  Different zombie variants can focus on direct combat, high durability, speed, tools, building, or route creation.

• Zombie Animations
  Additional animations improve the visual presentation of zombie movement and actions.
