Use the Unity Analytics Service Remote Settings feature to change values on your Analytics Dashboard which control aspects of your game or application. For example, if you are concerned that some levels in your game might be too hard or too easy, you can create settings that control the difficulty of your level bosses, letting you tune gameplay without releasing an update.
After you make changes to your Remote Settings, every computer or device starting a new session of your application downloads the new configuration values. No update to the application is necessary. You can connect Remote Settings to individual GameObject properties, or you can read the key-value pairs directly in code and provide your own logic for handling setting changes.
