Bungie Studios has unvealed a trailer for Halo 3. The next instalment of the series, which is due out next year, is to be launched on Microsoft's Xbox360 games console, and apparently cinematics are going to be as vital a part of the game.

The trailer was built to have minimum impact on the development process, and while it required long hours and hard work from many, many Bungie staffers, it utilizes real-game assets, fiction and locations from parts of the "real" game.
