Portal now free on Steam

Download and play the hit puzzle game for nothing.

Valve's only gone and made everyone's weekend by making the original Portal free to download on Steam - obviously if you've already got Portal then your job is to ensure everyone you know goes and downloads it.

Sure it's not as amazing as Portal 2, but it's still pretty great and free. Once you're done with Portal be sure to check out Portal 2 too.
