Black Dog Pack:
Anyone who has redeemed their code should now see this being available from today's client update. If you are yet to receive your code, the final batch of these are being sent out this week. NOTE: if you ordered through any retailer other than the official Xbox/Windows Store, you will need to contact the retailer to receive your code as this is not handled by Rare.
PC: Launch the Xbox App and keep a lookout for a message from Xbox Live containing the Black Dog Pack code.
Xbox: Keep an eye on your messages. A message from Xbox Live should appear containing the Black Dog Pack code.
Mobile App: Codes can't be seen on Mobile. Please check through one of the methods above or through the browser.
Already redeemed your code but can't find your items?
Under normal circumstances, items can be found in the relevant in-game chests after the code is redeemed (e.g. outfit will be in the clothing chest).
The link below will provide a step by step process on how to find these items.
Other bonus items:
The guidance in the paragraph above also applies to the Ferryman Pack, Mercenary Pack, Midnight Blunderbuss and other bonus items redeemable by code. However, distribution of these codes is not handled by Rare.
