Believe

"A hero is more than a person, a hero is a belief. A belief that, against impossible odds, the world can be saved—and that the world is still worth saving. Heroes inspire that belief in us. They renew our faith and give us that most precious of all gifts—hope. The world needs heroes. That's why, when a true hero arrives, the world will honor him."

- Xbox.com introduction of "Believe". "A hero need not speak. When he is gone, the world will speak for him."

- Magazine Ad "He's received the highest commendations for bravery. Countless decorations for honor and selflessness. But Master Chief's greatest achievement reaches far beyond what any medal could ever hope to commemorate. For the men and women of the 26th Century, he is a human embodiment of possibility, the last Spartan standing against an angry tide. This strength of spirit is forged through his legend. Jericho VII. The Battle of Reach. High Charity. Tales rife with sacrifice and courage. Tales that grow, flourish, and inspire. And while he shapes his own history, he in turn shapes the history of all who follow. For no matter what horrors are released upon the day, they cannot match the reply of soldiers emboldened with his spirit, an army of Master Chiefs unto themselves."

- Magazine Ad Believe is a Microsoft marketing campaign for Halo 3 produced by New Deal Studios. It features the word "Believe" as a tagline, and appears to be honoring the legacy of SPARTAN-117, citing him as a hero of the United Nations Space Command whose brave actions inspired other servicemen during the Human-Covenant War.

It includes handouts, live-action TV commercials, magazine page advertisements, and Xbox live marketplace ads.
