Redeeming Call of Duty items with a CDK is a simple process. However, keep in mind that each Activision account linked to a Steam account can only redeem a CDK once. For example, if you receive two CDKs of the same type, you will only be able to use one. Attempting to redeem a second CDK will result in a message indicating that it has already been used.
Follow the steps below to redeem your items:
Complete the tasks outlined in the event to earn redemption opportunities. If you win the "90's MIX PACK," the prize will be sent to you as a CDK.
To redeem your CDK, you need an Activision account that is already linked to your Steam account. After logging in to the Activision website, you can enter the CDK and complete the redemption process.
Once the redemption is successful, log into the game, and you'll find your new items in your inventory.
