Xbox One games are heading up to the cloud and down onto myriad other devices starting in 2019. Microsoft on Monday announced Project xCloud, which it refers to as “global game-streaming technology” that will allow users to play their console and Windows PC games on mobile devices and more.

With Project xCloud, Microsoft aims to provide a similar play experience on mobile devices as they get on Xbox One systems and PCs. The biggest hurdle, as is typical with game streaming, is minimizing lag. As the company continues to work on that, Microsoft said that it has also come up with a way to translate Xbox controls to mobile.
