Just got back from e3.
Hellmutt, I couldn't find any home codes. I even asked a few Sony employees and they said they didn't think there were any this year. However, if you're interested in buying Gauntlet on Steam, I have a code for a free helm. Funny story: for promo for Gauntlet, they had a food truck and were giving away free turkey legs so long as you tweeted NEED FOOD BADLY.
As a consolation, the gauntlet codes is yours, or I can mail you a Sony lanyard or a large t-shirt for the game Dying Light (http://dyinglightgame.com/
) PM me if you're interested.
Happy to share my impressions of what I got to play if anyone wants to hear. Spent the full 3 days there, so I got to play/watch almost everything I could on the show floor.
