About TMZulu/ZHC

ZHC is a headless client system for Arma 3 that enables server administrators to distribute AI unit processing across dedicated headless clients to improve performance. It was originally developed for The Myrmidon Legion community before being released as a standalone mod for the broader Arma 3 community. The system relies on CBA (Community Based Addons) for its core functionality and configuration.

The mod provides extensive customization through CBA settings and keybinds, allowing administrators to adjust timing, set headless client limits, and rebalance unit distribution. Core features include real-time FPS monitoring for both server and headless clients, a message-based debug system for troubleshooting, and support for emergency offloading when headless clients or Zeus disconnect. It also includes compatibility with popular mission-making tools like Achilles, Ares, and ZEN for garrison operations, plus utilities like unit blacklisting and prevention of improperly equipped units.

The project is designed to be flexible and expandable, accommodating both small community servers and large-scale operations. ZHC is distributed under the GPLv3 license and welcomes community contributions through bug reports and pull requests on its GitHub issue tracker.
