Nvidia has announced that Valve's Portal will be available on its hand-held Shield console as of May 12th as well as launched a rather interesting teaser campaign which suggest that Half Life 2 is coming to Shield as well.

Portal will hit Google Play store for US $9.99 and will be exclusive to Shield. It will definitely be nice to see how this classic 2007 game will look on Shield but it is surely a great win for the hand-held console.

On a similar note, Nvidia has sent out a rather interesting teaser to select members of press in form of a green crowbar. Although there are not many details regarding it, the sentence "What would Gordon do?", as well as clear Half Life 2 and Shield logos suggest that we will see Gordon Freeman and Half Life 2 on Shield sometime in the future.
