Fortnite Keyboard and Mouse for Xbox One
Fortnite will allow mouse and keyboard play on Xbox, with one caveat, mouse and keyboard players will only be matched up with mouse and keyboard players.
Meaning, you can’t stealthly hook up your mouse and keyboard to your Xbox, and go against players playing with controllers and pretend you are MLG. So, that’s good.
This was announced at the Microsoft #X018 Expo in Mexico City, November 10, 2018.
