Halo 3 is HERE. and It has proven to be worthy.

"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."
