Stadia Pro includes monthly free games such as GRID, Destiny 2: The Collection, and Thumper, along with 4K resolution and 5.1 surround sound. Google did say it'll default the resolution to 1,080 pixels in order to reduce the amount of bandwidth the service uses as more people are online due to lockdown orders implemented across the US because of the coronavirus pandemic. New users who get the upgraded pro subscription can cancel it at any time during the free two months or continue with the $9.99 a month membership.
Stadia can be played on select Android phones on the official app, which is also available on iOS although it doesn't play games on iPads and iPhones. Users can also stream games on the Stadia website on their computer or laptop while those interested in using Stadia on a TV will need a Chromecast Ultra connected to it. There is an official controller for the service sold by Google, but some Bluetooth controllers will work, including the ones used for the PS4 and Xbox One.
