The map is definitely being cooked into the package as I can open the command console (tilde key) and type “open MAPNAME” and it opens without a problem. I’m packaging it by adding it to the map listings under the packaging settings. The game is attempting to run in Offline mode (as done in the BeginMainMenu function of shooter game) and then loading the map. Theoretically this should just run the map, unless I specifically need something like ?listen at the end of the URL.
As for the string shootergame is using, it’s the following (taken from the config game file):
[/Script/ShooterGame.ShooterGameInstance]
WelcomeScreenMap=/Game/Maps/ShooterEntry
MainMenuMap=/Game/Maps/ShooterEntry
