How To Update Your Action: Source Server

By default, Game Host Bros Action: Source servers check Steam for a new Action: Source update whenever they restart and download only the files that changed, so your server stays on the same version as players. Your configs, maps and settings are kept.

Turning Automatic Updates On Or Off

While Automatic Updates is on, your server checks for an update every time it starts, so a restart installs a new version once it comes out. With it off, your server stays on the version it has; turn it back on and restart to update.
