Safe Zones
Safe Zones was described as an Arma Reforger add-on for damage-free areas that could be managed through Gamemaster or commands.
Archived and unpublished: The current repository README says “Not published - YET,” and the site's project catalog marks the repository archived. No Workshop install link is listed here.
Documented scope
The README describes protection for players and vehicles, temporary or persistent zones, configurable shapes and sizes, and entry or exit notifications. It lists #safezone help and #sz help as command hints.
Because the README says the mod was not published and the project is archived in the current catalog, do not treat these notes as installation guidance for a live server.
