Ambient City Characters – Security & Emergency is a modular character pack focused on uniformed and emergency service roles commonly found in modern urban environments. This includes military personnel, police officers, and firefighters designed for believable background population and environmental storytelling.

These characters are intended for ambient use cases such as patrols, emergency scenes, security presence, and crowd simulation rather than hero gameplay.

Each character is fully rigged using Unity’s Humanoid system and is compatible with standard Mecanim animation controllers, including the Ambient City Animations pack and other humanoid animation sets.

Characters include a comprehensive set of blend shapes, including full ARKit-compatible facial blend shapes, enabling facial animation, lip sync, and expressive performance if required.

This package is designed to integrate seamlessly into simulation-driven city scenes, AI-controlled crowds, and large-scale urban environments where authority and emergency roles are needed.
