Everything seems pretty much stock. My inventory doesn't contain anything special either. Are the items level restricted? I completed the introduction portion and can't find anything extra at the tower vendors also.
You are not the only one. At Bungie's forums, there are posts similar to this, and they say to have solved the problem. http://www.bungie.net/en/Forum/Post/68975633/0/0
"If you are missing any content when you log into Destiny, simply close the app, go to your playstation (or xbox) settings, restore licenses, Go to Destiny - related content, Download expansion pass and limited edition content, Go back into Destiny, Talk to Tess ...???... PROFIT"
If you're looking for a definitive answer to this... The solution is to download the add-ons. The items are not unlocked in-game but rather as separate downloads. These downloads should be available without charge if you have purchased the package. If not, you may have to 'restore licenses' in your dashboard settings.
- Destiny Collector's Edition Digital Content Pack
- Vanguard Armory
- Destiny Expansion Pass
You may need to close and re-open Destiny if you download these additions while the game is running.
Afterwards, you can claim the items themselves by visiting the the special orders kiosk and the Vanguard Armory by visiting the Tower.
To locate the Vanguard Armory, visit the Quartermaster using the location in the map below.
You will have a selection of level 5 weapons and armor, each at a cost of 250 Glimmer.
