So I am trying to play offline mode, my network is a secure network that requires a password and I dont want to have to disable it to play offline mode. There is supposed to be a message that shows up that says authetication required and gives me the option to play offline, that does not happen. So anyone has any ideas please let me know.
The only way to play offline is to launch the game while the computer is disconnected from the internet. If you want to keep your network up, you can disable the network card on the computer itself.
Know that there is DRM that requires you to log the game client into Battlenet every 30 days in order to continue playing offline.
