Hi TheChosenElite1!

Thanks for posting! For pre-ordering Call of Duty: Infinite Warfare, you will have access to a 1,000 Call of Duty points, which you can download following the steps below:

• From the Home Screen, navigate to Store and then select Games.
• Select Search games store.
• Search for Infinite Warfare.
• Locate and select Call of Duty: Infinite Warfare CP Incentive.
  
• Select Download.
• Re-launch Call of Duty: Black Ops III after the download is complete. Your points have been added to your account.
  

As stated in Call of Duty: Infinite Warfare's description, you will receive 1,000 Call of Duty points instead of Crypto Keys.

Let us know if you're able to download that!

Hey there!

You can grab the supply drop by searching "Infinite Warfare" on the Xbox Store with the account that purchased the game and selecting "Call of Duty: Infinite Warfare CP Incentive". This supply drop is not going to be sent out as a code.

This only applies to those who've purchased digitally through the Xbox Store.

Hey there Magik Manny!

To make sure, are you searching for Infinite Warfare while in the Xbox Store and selecting Call of Duty®: Infinite Warfare CP Incentive? You'll need to download that content in order to receive the 1000 CP. Let us know if you're still having trouble
