Jason Trent with GoozerNation writes: "I had a very special opportunity to get some hands-on time with Portal 2's cooperative campaign during this year's PAX Prime. Upon parting ways, the Valve employee I was playing with handed me a card and directed that I take a picture of a code on the back and send it to him in an email. About a month had passed when I received an email from the person in charge of the Valve store asking for my physical address so that they could send me some "swaggy goodness." Finally, a few days ago a package arrived from the Valve Corporation, and what did I find inside? Well, have a look for yourself. April 18th can't come soon enough."
