No, it’s not through us, but if you go to Behemoth’s forums, all you have to do is post “Behemoth loves me!”, and they’ll send you a code for a free King DLC pack. Act fast; there are around 1,834 replies at the moment, and I’m not sure how many codes they have, but you might as well try! Go here now!
Update: They just ran out, but bookmark the page. Behemoth says they might unlock the thread again if they have more codes.
