Finally, somebody agrees with me. "The campaign is the part that the developers spend the most time on and it's the heart and soul and the foundation of the multiplayer which people will inevitably spend days, even weeks on," -M3RKMUSIC
remember on mw remastered the End Game and the Mile High Club, that was the best, especially "All ghilied up" Now, if your talking about infinant ware- fare, yes it needs improvement.
IW was an epic fail of a multiplayer and zombies mode, but its campaign was one of the best in the series. My favorite campaign was either ghosts, COD 4, or bo2.
