Once xCloud integration kicks off on consoles, anyone using an Xbox One, Xbox Series S or Xbox Series X can simply click play on an Xbox Game Pass game and immediately start playing it via stream, effectively allowing players to try games before they downloading them (costing you both time and data).
Microsoft is bringing its Xbox Cloud Gaming (xCloud) service to Xbox One and Xbox Series X/SX consoles later this year, allowing you to download games and try them out before you commit to saving them to your console.
The service will also allow you to play Xbox Series X/S exclusive games (such as Microsoft Flight Simulator and The Medium) on Xbox One, though the former won’t be viable at launch – though it is “coming in the future.” xCloud integration will be available for Xbox Insiders in fall, before coming to other users Holiday 2021.
As per Microsoft, over 100 Xbox Game Pass titles will be available as part of this first wave of xCloud integration.
