Portal Coming To Android Devices 'Soon'

Valve, in association with NVIDIA, is bringing Portal to Android devices. A full port is in the works, and the same will arrive for NVIDIA Shield 'soon'. Additionally, the game won't be locked down to NVIDIA chipsets, meaning just about any (powerful) Android device will be able to run the game (which can be sideloaded using the APK file). Portal could be released for all Android devices at a later stage.
