Microsoft is making good on their September promise to bring mouse-and-keyboard input support to the Xbox One. Starting this Wednesday, November 14, select titles will receive updates that will allow them to be played with a mouse and a keyboard instead of a traditional controller. The first titles to receive the update will be Fortnite and Warframe. Microsoft will also partner with Razer to release "Designed for Xbox" branded mice-and-keyboard sets.
