Call of Duty Black Ops 4 may not have a campaign but could have battle royale

There is also a rumor CoDBO 4 will get a battle royale mode, just like PUBG and Fortnite. We'll have to see, personally I don't know how I feel about this. I never really cared that much about the single player, but this would turn Call Of Duty into a strictly multiplayer game. No internet, no game. On the other hand, how many people spend most of their time in Call of Duty single player?

I feel conflicted about this, what are you all thinking?
