What does it do?

The Headless module allows mission makers to quickly offload large numbers of AI units, crewed and uncrewed vehicles, and static objects to the headless client using a powerful caching and respawning system. Headless AI also includes a series of AI functions which will allow a mission maker to issue various commands to AI groups and units. The use of headless AI requires a headless client to be connected to the server. This module should always be tested in the single player editor, do not use the multiplayer editor.
