Showing their appreciation and support to those serving in the military, Activision is partnering with the USO to bring entertainment to the troops this holiday season. The company is using Call of Duty and Guitar Hero to make a difference in the lives of service members around the world, by offering them a taste of home and giving them a break from their day to day duties.

Veterans Day will mark the official start of the holiday promotion when Activision releases the highly-anticipated Call of Duty: World at War. For the launch, Activision and GameStop, will host pre-release events at GameStop locations in San Francisco and Washington, D.C. Fans of the game can play in real-time, tournament-style competitions against active servicemen and women stationed at Fort Drum, NY, and 29 Palms, CA.

A $10 donation will be made by Activision to the USO for every copy of the game that is purchased, up to $20,000 total, at the Washington, D.C., GameStop store during the pre-release event.
