The Xbox One has moved to implement mouse and keyboard support on a system level, but in a concession to concerned fans the support can only be enabled on a game-by-game basis.
Microsoft announced the news through a post on the Xbox Wire, saying that platform level support for mouse and keyboard will be added to the Insider branch of Xbox One builds — basically the beta version — within the coming weeks.
The new functionality will be disabled by default, however, meaning that developers will have to actively enable and decide how they want mouse and keyboard support to be implemented. "It’s important to note that mouse and keyboard support for games is added on a title-by-title basis, entirely at developers’ discretion. For all other titles, nothing changes," Microsoft wrote.
One of the first titles to begin testing the functionality will be Warframe. Xbox corporate vice-president Mike Ybarra also noted that developers would have free reign to establish matchmaking pools based on inputs, if they so choose.
The platform level support, however, will do little to qualm anecdotal complaints about players already using mouse and keyboard in multiplayer games through third-party accessories.
Any Xbox users that want to trial the new support as soon as it rolls out can do so by joining the Xbox Insider ring. Details on how to do that can be found here.
