Play Portal on any Android

Ah yes, who doesn’t love a good game of Portal? If you are lucky enough to own an Nvidia Shield (or any Tegra 4 device), you already have access to the game plus more exclusives. But what if you do not own an Nvidia Shield? Well there is still a way to play Portal thanks to an app called GLTools. GLtTools will emulate the Tegra 4 drivers, so that the app thinks you are using a Tegra 4 device.
