Would it be amazing if they actually made a game that included everything from Black Ops 1 & 2 and Modern Warfare 2 & 3 to make the Ultimate COD game, the game would included every map from these 4 games including Spec Ops and Survival with 8 new maps and a whole new campaign and 4 new Zombie maps and Spec Ops Levels. This would be the Ultimate COD game ever. Leveling up your guns like in Black Ops 2, level up to get new stuff like in Modern Warfare 2 & 3, play against bots offline, have up to 10 slots to customize your classes.
