Popeyes Chicken

i just spent some time downloading the game maybe a hour or so. I was expecting to be able to play multiplayer or campaign at most. come to find out it only install warzone. my game case doesn't say Warzone its says modern warfare. now why did it only install the free part of game instead of the game i actually paid for. now i have to spend more time downloading modern warfare just to play multiplayer. warzone should not be a addon to a game since the addon seems to be bigger than the actually game which is crazy in my opinion
