Call Of Duty: Modern Warfare 3 features a multitude of mission-based like Modern Warfare 2 as well as survival Special Ops modes where players will have to keep fighting until they get overrun by increasingly tougher waves of enemies as you progress.

Activision celebrated composer Brian Tyler announced that they will donate all proceeds from the Call of Duty: Modern Warfare 3 soundtrack to The Call of Duty Endowment, a non-profit, public benefit corporation that seeks to help returning soldiers transition back to civilian life, find work and establish careers.

“We couldn’t be happier to have Brian Tyler onboard for Modern Warfare 3,” said Eric Hirshberg, CEO of Activision Publishing, Inc. “If you’re an action fan you certainly know his work. It’s a pleasure to partner with Brian Tyler and Call of Duty fans around the world to assist real-world soldiers in need.”

“I am so excited to be the composer for Call of Duty: Modern Warfare 3,” said Brian Tyler. “I feel privileged to be able to contribute to the building of the Call of Duty Endowment. It is a true honor!”

Tyler has scored more than 50 films, including Eagle Eye, Fast & Furious and The Expendables. His elemental grasp of the action genre has yielded a stunning 20-track original score for 2011’s most eagerly awaited entertainment release. The soundtrack is now available for digital download at iTunes, Amazon, Rhapsody and other major digital media retailers for $.99 per track.
