If you’ve got an Xbox and Castle Crashers (and if not, why not, damnit!? ;)), then you’ll be interested to know that the King Pack DLC that adds a few characters, weapons, and a pet; can be obtained for completely free if you act fast enough. The Behemoth, the developers of the wonderful little game, wanted the DLC to be free, but MS said no, so they priced it at 160 points (2 of our human dollars). So The Behemoth went and bought a ton of these DLC packs and are now giving them away for free.
So, what do you have to do to get a code? Well, just go to the Behemoth Loves Me thread on the official forums and make a post stating, you guessed it: “Behemoth Loves Me”. Then wait patiently as they manually send you a code that you can punch in on Live.
