Turret AI System is a fully C++ driven, modular turret Plugin for Unreal Engine 5, designed for developers who need flexible, production ready turret behavior with full network replication.

The system is built around clean C++ architecture with minimal Blueprint usage and is intended for seamless integration into existing UE5 projects. All gameplay logic, AI behavior, targeting, shooting, and replication are implemented in C++. Blueprints are used only for configuration, visuals, and optional debug or cosmetic extensions.

This asset includes a demo level with multiple turret examples, showcasing both standard and experimental setups. All meshes, VFX, and sounds included in the project are placeholders intended for demonstration purposes. Developers are expected to replace them with their own assets.
