It’s based on Epic’s Multiplayer video series so there’s not much to it - it’s just an interface for creating and joining sessions (in Lobby_Level) and after joining a session you enter Network_Demo_Level and can spawn a male or female character and assign a name to it. You can try it out with Launch Game from the .uproject file, the menu will open on BeginPlay. Supposedly you can have other PCs join through the Steam subsystem by unchecking LAN but I haven’t tried it out.
