Is battleborn Online only.?

Does battle born require you to have an online connection. Or can I play it offline at home with a friend.

Always on - see here

I have downloaded the open Beta (played CTT) and was also under the impression that Battleborn was offline playable for Story missions. Gearbox were a little hazy about this.

They have confirmed online only so i will not be purchasing. I read this after downloading so that was a mistake on my part.

I currently play Rainbow Six Siege and cannot play solo terrorist hunt offline and this pisses me off.
