Treyarch has treated https://www.trueachievements.com/Call-of-Duty-Black-Ops....htm
players to a couple of preview videos of the upcoming "Awakening" DLC extension. The first preview looks at the "Rise" map while the second looks at "Gauntlet".

The sound in the exported stream is either very quiet, or my speakers are very poor. However, you will be able to see Treyarch's own David Vonderhaar taking us through some multiplayer matches as he does battle on the new map and screams at his team mates to "go-right, move here, flank left":
The "Awakening" DLC in Call of Duty: Black Ops III
is still without a solid release date and won't be available on the Xbox 360 version.
