Popular GPU developer Nvidia has today announced that Valve's classic titles Half-Life 2 and Portal are now available on their Android-powered handheld device, the Nvidia Shield.

This marks the first time Valve's titles have made their way to a handheld or Android platform, where they are currently available through Google Play for $10.99 each. "Nvidia has done a remarkable job bringing both Half-Life 2 and Portal to Shield," said Valve's vice president of marketing Doug Lombardi in the announcement. "We're playing both games here on our Shields and fans of both franchises can expect the same gameplay they've come to love on the PC."

A more recent update to the handheld has also enabled users to remotely stream games from their PC to the handheld, however this is currently still in beta.
