Nvidia CEO Jen-Hsun Huang had a "one more thing" announcement at his GTC keynote this morning, and that was news of Valve's Portal game coming to the Shield handheld.
While Shield owners can already play Portal on their devices through GameStreaming from their Steam accounts, this new version will be entirely standalone running natively on Tegra 4 and won't require an Internet connection.
"Nvidia has created a very powerful and unique device with Shield," said Doug Lombardi at Valve. "Our companies have a strong history working together and we're looking forward to Portal's arrival on Shield."
Neither company would commit to a release date other than "coming soon." We hope that this ushers in other ports of popular Source engine Valve games to Shield.
Also announced today is a temporary price drop for Shield down to $199 and remote GameStreaming.
Stay tuned for more from GTC.
