Advanced Zombie AI Pro

Documentation | Support

Advanced Zombie AI Pro is a complete, profile-driven zombie behaviour system for Unity, designed for horror, survival, shooter, stealth, and open-world games.

Instead of giving you a simple “see player, chase player, attack player” enemy, this asset gives you a full zombie AI framework with detection, investigation, searching, hunger, crawling, damage reactions, audio behaviour, ragdoll death, and easy integration with your own weapons and player health systems.

Build slow shamblers, aggressive runners, crawling zombies, stealth-sensitive infected, hungry corpse-eaters, or mixed zombie types using reusable ScriptableObject profiles.

Key Features

• Profile-driven zombie AI: Create multiple zombie types using reusable ZombieProfile assets. Configure movement, vision, attacks, health behaviour, search logic, crawling, hunger, stun, and death settings without rewriting code.
  
• Advanced stealth-friendly detection: Uses up to five target body regions such as head, chest, lower body, left, and right. You can decide how many visible regions trigger inspect mode or full chase, making partial visibility and stealth gameplay possible.
  
• Complete zombie behaviour flow: Includes Idle, Wander, Alert, Chase, Inspect, Search, Attack, Hit, Stun, Eat, and Dead states for more believable zombie behaviour.
  
• Standing and crawling zombie support: Zombies can walk, crawl, fall into crawling mode, or enter a second crawling phase after taking lethal damage.
  
• Combat, damage, and death system: Includes hit reactions, stun behaviour, health events, animation death, ragdoll death, and easy weapon/player health integration.
  
• Hunger and corpse eating system: Zombies can detect and eat dead bodies or food targets, useful for horror scenes and dynamic enemy behaviour.
  
• State-based zombie audio system: Configure idle, wander, chase, inspect, attack, hit, stun, eating, crawl, and death sounds using ZombieAudioProfile, with loop audio, timed one-shots, random clip selection, and 3D audio settings.
  
• Noise reaction and group alerting: Attract zombies using gunshots, explosions, alarms, footsteps, or custom noise events. Zombies can also alert nearby zombies when they detect a target.
  
• Editor setup tools and custom inspectors: Quickly prepare zombie prefabs with setup tools that add required components, audio sources, health, AI, ragdoll support, and other references.
  
• Debug-friendly workflow: Built-in debug options help visualize and tune detection, behaviour states, targets, health, and audio playback during development.
