NEXUS – Modular Melee Enemy AI System

Create fully functional melee enemies in minutes.

NEXUS is a drag-and-drop enemy AI system that includes ready-to-use NPC prefabs with combat, patrol, chase, procedural animation, audio, VFX, health, and optimization systems already configured.

Just place an enemy in your scene and start building your game. Add the "Player" tag to your character and you're all set.

The included NPCs are fully modular. Replace the character model, mesh, textures, skins, materials, or visual style while keeping the complete AI, combat, animation, and optimization systems.

Choose between three AI behavior modes depending on your project:

• Utility AI for context-aware decisions

• Persecutor for relentless enemies that never stop chasing

• Territorial for guards and enemies that defend an area before returning to patrol

Designed for games that require scalable enemy AI while remaining easy to customize.

Ideal for:

• Action RPG

• Survival

• Dungeon Crawlers

• Hack & Slash

• Horde Games

• Open World

• Voxel Games

• Stylized Games
