A winner will receive his key via email.

p.s. don't jump at conclusions,i did win same type of DLC here a week or so ago,but it is activated and on my account.Check before you point fingers.
I even had a case where i won 2 of these DLC's here at the same day,and i reported 2nd one,requesting a reroll since it was unfair.
This key is new,unused,and is not related to this site(other than i'm giving it away here,since i've got it already).

Cheers
