Valve announced that the Steam Link app will let players get a Remote Play streaming experience for their Steam games to their iOS and Android devices, offering the same kind of service that Microsoft, Sony, and Nintendo all variously offer or have offered previously. Now, the beta for Steam Link App (which is what the app to enable this will be called) is available for Android.
The Steam Link App will work with a variety of Bluetooth Controllers (including the Steam Controller). The app is available to download ow, and will have a really straightforward setup process, Valve promises. For now, the Android client is available to download from the Google Play store, but you should soon be able to download the iOS version off of the App Store as well.
Hopefully, this works as well as advertised! I would love to play Civilization 5 on my iPad Pro, for example…
