This BepInEx plugin adds headless dedicated server support to ATLYSS, enabling you to run the game in a terminal as a dedicated server — no graphics or UI needed.
⚠️ This is for hosting servers only. It will disable itself when the game is being launched normally.
As long as the mod loads under BepInEx and applies during host/server initialization, it will work seamlessly with this dedicated server plugin.
-batchmode -nographics -server
ATLYSS.exe -batchmode -nographics -server [options...]
You must include at least-server before your own custom arguments for the mod to activate.
Specifying -batchmode -nographics is optional, but desirable to enable proper headless support.
The mod also generates start_dedicated_server.cmd on Windows and start_dedicated_server.sh on Linux that do it for you, however you might need to have the Steam client active for it to work correctly.
