Hello Brute, The requirements of this emblem are not completely known. Here is a Bungie employee's reply regarding this emblem. https://www.bungie.net/en/Forum/Post/197022346/0/0/1 [quote]Occasionally, Bungie will disperse in-game items, such as Emblems, through emails to select groups of players who meet specific qualifications. These qualifications change from offer to offer. However, the initial qualification to receive these emails is that players need to have their Bungie.net profile settings configured to allow us to send announcements and notifications to their verified email address. If you are unsure if your settings are configured correctly, please see our help article: https://www.bungie.net/en/Help/Troubleshoot?oid=13784 Also, please note that once your settings are configured as shown in the picture in that linked article, it may take some time for you to begin receiving emails from Bungie.[/quote]

From what I understand Bungie gave it out only to certain people and only that once, the requirements were unknown.
