[Update: Funny! The contest at PAX that has you scanning QR codes hidden around the convention center doesn't work on a Windows Phone. It requires an app that is only available on iOS and Android!]
You've seen the Halo 4 Mountain Dew App, you've even taken a journey into the very Hall of Mountain Dew itself, but are you prepared for the new Dew and Doritos Xbox One giveaway? I thought not. A promotion called "Every 2 Minutes" will be running from September 30th until November 5th (a hint at a release window perhaps?), allowing you to win an Xbox One console by "banking" codes from packages of Dew and Doritos.
If you're at PAX you can win one on Sunday at a live event along with a bunch of other goodies, and there are over 100 QR codes signs hidden around the PAX Prime convention center that you can scan for points. You can also stop by the Dew/Doritos booth near the PAX queue room.
Yep, this is a thing.
