Hikkan is famous with his scams. This time he gives a dlc to a game that no one can play and full refunded at steam because it asks your phone number and even you have the phone number game wont let you in. Just check steam comments and you will understand what I mean. So this dlc is all fake. You can ask your friends for which fake key he gives to you. They can check through steamdb extension or other ways. He gets punished for scamming few days and regain his id back later. One of the indiegala flaws.
press his id and you cant find it now. He is punished but oh yeahhh he will return back.
