Update: The video’s being pulled apart all over the web. See here.
It’s here. It shows city streets burnt out after a meteor impact and a “Halo 3″ logo, followed by the words “Prepare to drop.”
The video has the Microsoft Game Studios logo at the end of it.
And that’s that. Watch it. We’re just sorting out a local version.
Update: You can watch it after the break now as well.
