After waiting to know the release date of "Call of Duty: Black Ops III's" third DLC pack, Activision finally announced the details surrounding the new expansion, which is titled "Descent."

The Origins characters will once again embark on a horrific journey after their escape from Zetsubou No Shima. In this new DLC, the characters will find themselves in Stalingrad in the new chapter of the zombie experience, "Gorod Krovi." In the war-torn city of Stalingrad, the heroes will yet again face unimaginable enemies described to be "remnants of a battle between giant mechanized soldiers and ferocious dragons."

The "Descent" DLC introduces new multiplayer maps Berserk, Rumble, Cryogen and Empire.

Berserk is a Viking village that has long been frozen with ancient sentinels as the guards to its entrance. Players will need to brave the blizzards in this medium-sized map to seize control of the center bridge.

In Rumble, players will come face to face with giant mechanized warriors. This stadium map hosts battles between giant robots and players will need to survive through pyrotechnics and fallen robots.

Cryogen is an isolated compound off the coast of the Dead Sea. This is where the most notorious criminals in the world will be taken and placed in frozen isolation.

"Call of Duty: Black Ops III" also brings a reimagined Raid map from "Black Ops II" in the form of Empire. The reimagined classic map features an authentic Roman villa that has been revamped by a modern-day billionaire.

Apart from the new maps and enemies, it is expected that Descent will also bring new weapons. It was even spotted that one character was carrying a "dragon-themed shield" that shoots out fire.

The "Descent" map pack will be available first on PlayStation 4 on July 12. Other gaming platforms will have to wait a bit longer, but it is widely speculated that the game will hit Xbox One and PC sometime in mid-August.
