I'm not sure if this is the correct name, I don't have the base game and it says "Riptide Survivor Pack DLC Retail".
In case there's anything wrong with the key, the giveaway name is incorrect, or whatever, I hope the winner would agree to delete this GA. If the giveaway name turns out to be wrong and we have to delete this GA, I wouldn't care whatever the winner does with the key. Once taken, it belongs to him/her.
