Our products using "Steam License Keys" are delivered via email, containing your personal serial key. All products which need to be activated on Steam are not delivered as a download, you will receive a so-called Steam License Key. In this case, we will send you the activation code for the product. After activating your Steam License Key in the Steam application (http://store.steampowered.com/), your product will be automatically downloaded and added to your Steam library. For more information about using Steam, visit the Steam Support page (https://help.steampowered.com/en/).
