The popular Ubisoft Plus service has been confirmed for a Google Stadia release within the final few months of this year. The uPlay Plus service is being renamed to Ubisoft Plus after the announcement of Ubisoft Connect which combines all Ubisoft services into one place.
Ubisoft Plus will continue to do what uPlay+ has been doing and will remain to be a subscription service to access over 100 games. This service will be coming to Amazon Luna first as a beta but will then expand to Google Stadia by the end of the year. Stadia Pro is not a requirement so those on the free version of Stadia can also sign up to the subscription service. Linking your Ubisoft Plus account to Google Stadia will allow you to play those games on a variety of platforms like normal with Stadia.
The exact release date for Google Stadia is still unknown but we do know it should be available by the end of December.
