Call of Duty: Black Ops 3's latest DLC pack 'Descent' is available to download now on PS4. It will likely release on PC and Xbox One in early August.

Descent introduces four brand new multiplayer maps:

Empire: Treyarch adapts its Black Ops III movement system to the Call of Duty: Black Ops II fan favourite 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 III.

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.

And of course, there's a new zombies experience too:

Gorod Krovi: Set in an alternate universe of Nikolai’s motherland, the 1940s Soviet Union. Players face-off against a swarm of mechanized zombie infantry and dodge hell-fire from aerial dragon assaults, all in the middle of a raging battle within the remnants of Stalingrad.

Descent is the third DLC map pack released for Black Ops 3, with one more pack expected to launch prior to Infinite Warfare's release this November.
