You will have a chance to win 1 of 25,000 Call of Duty: Vanguard beta code drops. If you are lucky enough to win a beta code, you will also be given an extra to share with a friend of yours. CDL Championships are mostly streamed on Youtube. You have the option to either watch it directly on Youtube or from the official CDL website. If you want to guarantee your spot in the giveaway, you must watch the CDL championships through the official CDL website, not Youtube. Make your way to the CDL website, log in using your Activision and/or Battle.net credentials, and watch the live stream. The beta codes will be given away randomly. The codes are in a limited quantity, so make sure you get to the site as soon as you can to increase your chances of getting the code. If you win, you will be notified on the CDL website and your companion app, if you have it installed on your phone.
