Hi,
normally you should be able to start the game in offline mode.
When the main menu is loaded, it will give the message that
only the single player is available in offline mode and you accept
and play.
Is there any error when you try to start the game?
I have this problem with BF1.
Just bought it on steam and I can't play it offline. I need to log in but how when I don't have net?
As ar as I recall, then you need to have an internet connection first time to register your account and soldier on the game.
After this, then yo can play the Campaign in off-line mode.
