The opening video for the Transformers movie video game is available online now and it is fan-friggin-tastic!  You can download it using this link.  Just right click and select "Save As..."

As an aside, some samples from the upcomming soundtrack are also available online.  There's Before It's Too Late, What I've Done, and Transformers Theme.  I don't know if they're any good or not as I'm downloading them as I type this.  I'll have thoughts on them tomorrow sometime.
