New Destiny Editions and Redeemable codes.

Collectors and Limited Editions should be available for pre-order.

Also, for those of you interested I'm pasting this from the Destiny forums on Bungie.net:

For those of you who did not know, on 14 AUG 2013, Bungie did a 5 trading card release at a live event! The participants were given five Limited Edition trading cards which contained online CODES to be redeemed at a specified Bungie site, which they wanted to be shared with anyone who was interested: Bungie: News: Destiny Trading Cards.

Since that time, a grand total of 17 cards have been released. At this time, it is unknown what these codes unlock, but there is speculation that each code may unlock exclusive content in Destiny or perhaps related content accessible only through Bungie.net.

Regardless, following you will find a COMPLETE list of all known cards that were released, which you can redeem immediately HERE. Best to get these entered before Beta begins!
