Same problem, no code, contacted amazon got same reply. Not happy with this, contacted them again, got this reply This is Shaun from the Games and Software Downloads department, I'm sorry about the issue with Destiny - Rise of Iron DLC and the Gjallarwing bonus. We are aware of this matter and we've reported it to the relevant team, who are researching the issue further. At the moment, however, I can confirm that only the Gjallarhorn is mentioned on the Amazon product details page (https://www.amazon.co.uk/dp/B01GSJ1RU8). "Pre-order and get the black and silver Iron Gjallarhorn Rocker Launcher." Situations such as this are rare and our goal is to help resolve any problems you encounter as quickly as possible. Thanks for your patience while we look into this. Watch this space?
