Video: The expanded Halo universe of Halo Wars

With the release of Halo Wars less than a week away, Microsoft has released a new video examining the expanded Halo universe present in the game. Believe it or not, Halo actually has a very detailed background. Over the years, it's been laid out in books, graphic novels, comic books and even ARGs. Still, for a great deal of Halo fans, Halo Wars will be the first time players get to experience the history behind the first three games.

Check out the video and learn your Halo history, because it's much more fun than learning about real history.
