Get Portal for FREE
Having been a fan of the title for a while, I wanted to take a few mins and let you know (just in case you havn't played it) that Valve is giving away their unique puzzle game for the awesome price of FREE.
No doubt to celebrate the arrival of their Steam service on the Mac platform all you really need do is download steam, make an account and claim for free copy of the game. Yes you read that right, Steam is now available for any Mac pc :)
The offer is valid up till the 24th of may 2010, so make sure you get there quick.
Head to their promotion page here, which directs you straight to the steam store where you can get your download.
Then just for kicks, here's a nice fanart pic of the main character of the game, or rather the one you play :P Chell: (original here)
