After Destiny's cinematic introducing the story of the game's upcoming DLC, The Dark Below, leaked, Bungie opted to issue a more explanatory video. As seen on the video below, the developer diary-style trailer discusses the "one way trip" nature of The Dark Below's design. The trailer also introduces Eris Morn, the merchant and primary quest-giver that failed to defeat the DLC's main villain Crota in the past.
The Dark Below will launch on December 9 and adds new gear and maps to the game, which are also shown in today's video. The DLC will cost $20, and it is also part of the Destiny's $35 season pass program. Those that buy the expansion will also receive a new Sparrow vehicle capable of performing some fancy tricks.
