The remake of the best Call of Duty is almost here. When the Modern Warfare remake launches alongside this year’s Call of Duty: Infinite Warfare, the disc will be required to actually play the remake, or at least, through the digital copy.
At launch, Call of Duty: Modern Warfare Remastered will contain only 10 MP maps from the original Call of Duty: Modern Warfare game. Additional MP maps will be made available by 12/31/2016. Modern Warfare Remastered is a full game download (game disc must be inserted to play Modern Warfare Remastered).
I guess it isn’t surprising, as you could have theoretically bought the game, sold Infinite Warfare and kept the remake.
