The Google Stadia controller's wireless capability will only work on TV with a Chromecast Ultra at launch, Google has revealed.

This means that if you were planning to play Stadia games on your computer or phone while using its official controller, you'll have to use a USB-C cable.

Google also clarified that you'll need the official controller to play games through Chromecast Ultra.

The Stadia controller uses Bluetooth technology for setup and connects via WiFi for gameplay, mso you can't use it without a cable at first. It's still not clear when wireless play will be available for the other Stadia-compatible devices.

Google's Stadia game streaming service will debut on November 19th in the US, Canada, UK, Ireland, France, Germany, Italy, Spain, Netherlands, Belgium, Denmark, Sweden, Norway and Finland. The Stadia Founder's Edition costs $130 and includes a controller, a Chromecast Ultra and two three-month Stadia Pro subscriptions.
