Halo 3 ViDoc: And on the Seven7th Day...

This Halo 3 ViDoc was a promotional video talking about the release of Cold Storage and Bungie Day. Throughout the video several Bungie employees explore the Legendary Map Pack, explaining Cold Storage and how it's free. They then explain Bungie Day and how the Legendary Map Pack got a discount.

Trivia

 * In the video when the words "Love Bungie" the words "Keep it Clean" quickly flashes. Then when the Bungie logo appears at the end before the Xbox logo, you can see the Superintendent in the top right corner of the screen. These are references to the Keep it Clean trailer way before it was even released.
