Overview
The PUN packages from the Asset Store include several demos.
None is a full-blown game but each shows a practical setup of scenes and prefabs for some aspect of a multiplayer game.
Below, we highlight a few demos of the PUN Free and PUN+ package.
Download Photon Unity Networking Free
The Hub Scene
When you import PUN into a new, empty project, this scene should be loaded automatically.
If not, use Unity's menu:
"Window" -> "Photon Unity Networking" -> "Configure Demos (build setup)".
All included demos can be started from this "Hub Scene".
You just need to setup your AppID, build and run.

You can run the Hub in the Editor as well.
Some demos use the Console of Unity to log hints.
Double click a Console output line and you usually get to the code that printed it.
To learn more about the demos, open their individual scenes, too.
