Its probably never going to happen ever again and it wouldn't make much sense considering how the story is going for BO7 but lets just imagine what if we saw a celebrity cast map in BO7
How would feel if for that map specifically, you can't play as any other character that it isn't one of the celebrity cast crew?
For context for the map and how much it would cost activision to get the celebrity cast for the map, it wouldn't made sense if they didn't force you to use them
