Bungie built a Destiny statue for Gamescom, and this vid shows them making it
In Destiny, you will be able to play as a class called Fallen Captain, and these types serve to further demonstrate Bungie's outstanding ability to design cool helmets. Also, they built a physical statue of one and are taking it to their Gamescom booth. They filmed a little featurette about it, which you can watch below. If you don't care about statues, you should watch for the sweet original Destiny score that plays in the background.
