I happened to be doing some reading up on IGN about the release and decided to start backtracking through some of their articles. In the process I found an old article in which they give ALL of the redeemable codes that appeared on the trading cards thst bungie gave out at the world tour live destiny events. So without further adieu I present to you the link to access these codes. YOU MUST ENTER THEM UNDER YOUR NAME @ BUNGIE.NET. they will not work on this app. I already tried both ways. http://www.reddit.com/r/DestinyTheGame/comments/2fc0rt/am_i_missing_any_codes/ These codes simply unlock grimoire cards for your in game collection. EDIT***** The link listed above is now from Reddit, NOT IGN, it was provided by Svs, and it has an updated list of 25 codes to unlock various grimoire cards, emblems AND shaders.
