The bonus DVD included in the Collector's Edition of World of Warcraft expansion Cataclysm features over an hour and a half of video.
Films include Who is Deathwing?, a World of Warcraft retrospective, interviews with programmers and a piece on game design, according to the British Board of Film Classification.
The bonus DVD also includes the Cataclysm intro cinematic and major content patch trailers complete with director's commentary.
Deathwing is one of five Dragon Aspects and leader of the black dragonflight. In other words, he's a pretty big deal. He's also the main bad guy in Cataclysm.
Cataclysm will be released on 7th December. It's the third WOW expansion, and follows The Burning Crusade and Wrath of the Lich King – both hugely successful.
It introduces two new races: the worgen and goblins, and increases the level cap to 85. The Collector's Edition costs £59.99 in the UK.
