*slaps selp on head*
I subscribe to PC gamer, but after I read the magazine, I give it to my wife to take into work. (Had no idea about this code thingy)
I've given the wife a call and if the magazine is still there, she will grab it and pull it back for me. If she does manage to grab it, you can gladly have the code (I plan on buying Hellgate eventually, but not until I can get it for about $10 - so that should be a year or so)
