PlayStation 4 module owners may now enjoy the additional features of "Call of Duty: Black Ops III" with the release of the DLC 3, Descent, on July 12.

Descent contains a new chapter of the Origins Zombies storyline. Players are transported to a Stalingrad alternate timeline called "Gorod Krovi." The "Battle of Stalingrad" happened during World War II and is considered one the bloodiest battles in the history of warfare.

In "Call of Duty: Black Ops III" DLC 3 Descent, players go to battle against mechanized zombie soldiers and deadly dragons controlled by Group 935. Like the previous installations, soldiers are infected with Element 115, making them the most dangerous enemies yet.

Four new multiplayer maps are available on the new content. Players may explore an isolated cryo-prison, a Viking village frozen in time, a robot arena, and a lavish Roman villa.

One map is called the "Empire," which is a re-imagination of the fan favorite "Call of Duty: Black Ops II" Raid map. The popular chained movement gets a fresh upgrade as players explore the Roman Villa owned by a modern-day eccentric billionaire.

Another map is called "Berserk," a well-guarded frozen Viking Village. Ancient sentinels await players at the entrance and those who trespass the village should also fight their way through blizzards.

At the far off the coast in Dead Sea lies an isolated compound called the Cryogen where dangerous criminals are frozen. A lot of the action takes place in the prison's cryogenic tubes and it is where players get to enjoy wall running attacks.

The fourth map is called the Rumble, which is located in an arena where players go against giant robots. Action in this map happens in the arena as well as outside the stadium.

30 days after the release of Descent on PlayStation 4, it will be made available for PC and Xbox One.
