Destiny's upcoming expansion The Dark Below brings a boatload of new features to Bungie's multiplayer FPS, and the trailer above outlines what you can expect to see. Featured additions include new equipment, guns, environments, story missions, Crucible maps, a multiplayer Raid, and maybe even a Jacuzzi. Actually, that's probably not a Jacuzzi. Don't risk it. The Dark Below premieres on December 9.
