So far, Call of Duty: Black Ops 3's map packs have been quite impressive, mixing old and new content alike while keeping us engaged with new zombie chapters like Zetsubou No Shima and Der Eisendrache. However, we haven't seen anything yet.

Treyarch and Activision have officially announced Descent, the latest map pack for Black Ops 3, which will be arriving on July 12th for PS4, and coming at a later date for Xbox One and PC.

The main focus will be on a new Zombies mode called Gorod Krovi, taking place in the heart of Stalingrad. Not only will you have to contend with a slew of new zombies and robots, but also dragons. Yep, Call of Duty is getting all Reign of Fire up in here.

The four multiplayer maps that will be part of the pack are described below:

Empire: Treyarch adapts its Black Ops 3 movement system to the Call of Duty: Black Ops 2 fan-favorite map Raid. The re-imagining of this classic, medium-sized map features an authentic Roman villa that has been "recreated by a modern-day eccentric billionaire," where a classic map structure mixes with the new gameplay mechanics of Black Ops 3.

Cryogen: Located far off the coast in the Dead Sea, an isolated compound holds some of the world's most dangerous criminals in frozen isolation. Sentry towers keep watch over the small map's circular design as frenetic combat is funneled around the prison's cryogenic tubes, where opportunities for wall running attacks abound.           

Berserk: Ancient sentinels from a lost civilization guard the entrance to Berserk, a Viking village frozen in time. Players will fight through blizzards, and control the center bridge as they navigate this medium-sized map's wooden buildings, deadly rocky outcroppings, and tight chokepoints.

Rumble: Gamers battle amongst larger-than-life mechanized warriors in Rumble, a stadium where giant robots battle to the roar of the crowd. This medium-sized map funnels high-speed combat to the central arena, where players battle their way through fallen mechs and pyrotechnics.

The map pack goes for $14.99, and can also be downloaded by those that have purchased the Season Pass. Check out the trailer below!
