The Launcher is a helper application like any patcher but with one difference; It’s completely coded and designed in Unity. It basically allows the user to download your game, keeps your game updated at all times and checks file integrity.
With only one editor window, you can upload your build to your server. Compressing, version checking, file integrity control all handled by the window.
With only one single inspector script, you can configure the client completely.
Checking out the demo scene will provide lots of useful information on both
configuration and structure of the client.
