Call of Duty Modern Warfare is going to be the first AAA game to feature full cross-platform play between PC and consoles, but not much has been said about how things will work. Today, we have learned how the development team at Infinity Ward will make things as fair as possible.

On her official Twitter Profile, producer Candice Capen confirmed that Call of Duty Modern Warfare will employ input matchmaking when matching players with those playing on other platforms. This means that those playing on PC with a controller can be matched with PS4 and Xbox One players, while those playing with mouse and keyboard will not, just like in Fortnite.
