We would like to inform you that the following days the current DLCs of the game will be retired. This means that you won't be able to purchase them through the Steam Store.
All our DLCs so far sell cosmetic avatars. Since the latest patch these avatars can be purchased through the shop in the game under the Avatars section without the use of DLCs using the In App Purchase system of steam.
If you have purchased any DLC and since then you didn't log into the game make sure that you login so that your DLC will be enabled and you will get the avatar saved in our database.
