Here's How Google Chromecast Will Play Stadia Games Without An Official Controller
As Stadia version 3.15 begins to roll out through the Google Play store, a new feature called “bridge mode” has been spotted. As it stands, if you want to play games on Stadia using a Chromecast Ultra, you can only use a Google-made Stadia controller that works over Wi-Fi. With the bridge mode feature, however, you could use your phone’s touchscreen as a controller, similar to what you'd do when playing games directly on the phone.

It's not clear how Bridge Mode will be enabled just yet or how to link a phone, but we're sure an official announcement from Google will be made soon. Of course, you will need to be on the same Wi-Fi network as the TV or Chromecast Ultra for this to work. In any case, it is a rather nice feature that will allow more people to play games anywhere they have a broadband connection, phone and a Chromecast Ultra without the need for the Stadia Controller. It will be interesting to see what the control layout ends up being on a mobile device, so stay tuned to HotHardware for more info as this unfolds and let us know what you think.
