Amazon is promoting Activision’s Modern Warfare 2 with a campaign that tracks pre-release sales of the game across the US to find the city with the most pre-orders. As reported by Kotaku, the online retailer’s Call of Duty-est Town in America promotion is tracking orders placed through its Release-Date Delivery system for US cities with a population of 5,000 people or more. Once the winning city is determined, Amazon will donate a $5,000 gift card to a local charity. The winner will be announced on November 10. Read more at Kotaku.
