I was re-reading this topic and had no idea that Call Of Duty Black Ops 4 had no single player campaign, that is unusual for Activision, most times Activision were always known for their game quality, well, looks like I won't be ever getting Black Ops 4. More recently I purchased Call Of Duty 2 for the Xbox360, and Call Of Duty Black Ops 2, and Call Of Duty Black Ops 3 for Xbox360, I however had a lot of copies of Black Ops 1 for the PlayStation 3 that had disc rot.
I still had not ever played an online COD match, and have no interest in doing so.
