I'd be all for an achievement / trophy hunt co-op campaign type of thing. I've got most of the call of duty games (scattered across various sony and xbox platforms). I've forgotten which have coop campaign (seems like modern warfare and world at war at least do) but they're all pretty fun.
I did get around to playing a few rounds of gun game in blops4 today and enjoyed myself. I can almost forgive cod for not having a campaign since the mp is so robust BUT revisiting the game years later will be unlikely.
I feel sorry for those that bought into the limited edition variants -- it seems like spending tons of money on an investment that you know is going to tank
@BLUEVOODU wouldn't you agree?
