From now on, enter the draw by replying with either "360" or "PS3". Winner will be picked on Monday morning after Gamescom has ended. Good luck!
Right now, these codes can only be picked up at Gamescom. So unless you're at the Expo in Cologne, getting one of these codes is going to be pretty though.
I'll try and get more. However, for now, I will give out a code to one lucky Xbox 360 user.
Make a reply in this thread confirming your interest and I'll pick a winner (at random) at 5pm tomorrow. Depending on interest and if I can get more codes, I'll put back the deadline until after Gamescom finishes on Sunday evening.
