All I want to do is play the single player offline campaign and do you think I can do it. I've spent hrs and hrs if installing and downloading updates and repeating that and I still can't play a game. It keeps telling me I'm missing one or more single player dlc packs even know on the xbox its telling me game has no ipdates available. I'm a older guy that doesn't get much time to play games so this is very disappointing for me. Worst call of duty ever.
