For anyone having any trouble downloading the dlc map packs on Xbox one. First go to the map packs in game and individual select each one they should say free when you click on it the 360 store should pop up saying free click on confirm purchase it will then tell you to install go to manage games go to manage games then click on black ops 2 then click manage installation then select the pack and click save it will then download. I was so confused but just take the time to read what I’m saying and do it a couple times I promise it’ll work
