Microsoft has previously shown that it is working to bring mouse and keyboard support to its Xbox One. This was not a formal stand-alone announcement and instead, the first vice president of games, Phil Spencer, was announced in the Inside Xbox episode on September 25, 2018. The company added that the first game to get this support will be "long-running free-to -play MMO " Warframe. The support was scheduled to arrive in October through the Xbox Insider Program. But now the company has declared that mouse and keyboard support will arrive on November 14, and it will not be exclusive to the Xbox Insider Program.
Microsoft has now confirmed that the support will not be limited to Warframe at the launch, and there will be a list of other games that will receive support as well. And one of the early games to get support will be one of the most popular combat royal games in the world, Fortnite, from epic games. But that means players using mouse and keyboard on Xbox One play Fortnite will only be matched with other players who do so well to maintain parity.
Other games that will also receive support in November include Vermintide 2, War Thunder, Strange Brigade, Bomber Crew, Deep Rock Galactic. While other games like DayZ will receive support in the coming weeks.

Because most mouse and keyboard do not work with Xbox One, Microsoft starts a "Designed for Xbox" application that shows that hardware is manufactured with Xbox One in mind. Razer is currently an exclusive partner for the Xbox, and develops a designed Xbox mouse and keyboard combination that will be featured on CES 2019.
