I know most of you probably don't like Call of Duty, but I'm going to post the extra "Beta" keys that were sent to me by Xbox below. The "Beta" starts on October 21 at 10AM PDT/5PM GMT. The "beta" will run through October 24 at 10AM PDT/5PM GMT. I know this is when Battlefield 1 launches, but... meh.
All I ask is that you tell me which code you use. Thanks.
