The upcoming sequel to Treyarch's Call of Duty: Black Ops has just been officially revealed on May 1st, confirming details about the game's title, location, and other gameplay details. But for any fan of the first-person shooter franchise, one of the most anticipated features will be the new zombie mode.

New artwork teasing the undead shootout was recently launched, enticing fans to gear up for the next Black Ops release. The image itself doesn't reveal too much about gameplay, but illustrates a woman holding a gun behind her head. A red backdrop gives the picture a blood-thirsty feel, with the triumphant female shooter standing atop a pile of debris.

The developer also confirmed that the fan favorite mode will run on an improved multiplayer engine, which will allow double the amount of players and of course, double the zombies.

Treyarch have given their zombie team free reign to do pretty much whatever they want with the mode regardless of the direction the campaign is heading in, wrote in their Black Ops 2 preview.

The revamped second installment of Black Ops is set to bring new material and revitalize gameplay, with a war-torn Los Angeles serving as the futuristic Cold War battleground.

The campaign's pretty big and ambitious, Treyarch head Mark Lamia told VentureBeat. The multiplayer is pretty big and ambitious. And they really are creating another game with the Zombies there.

He also added that a staff of more than 300 people are currently working on the new game, most of which are located at Treyarch. This is different than the last title of the franchise, Call of Duty: Modern Warfare 3, which was developed by three different studios.

The zombie co-op mode usually features waves of the undead flooding in waves, which players must fend off in order to stay alive. Players receive money for each zombie kill, and are able to purchase more advanced weapons and upgrades. Different maps throughout the zombie campaign offer different offbeat features, such as the ability to play as JFK and Fidel Castro among other historical personas.

With the fresh theme featured in the upcoming Black Ops, it'll be interesting to see what kind of twists Treyarch ties into the game's undead version.

If you like zombies, you're going to be really happy with what we're doing with 'Black Ops 2.' It's our biggest, most ambitious zombies yet, Lamia said in the latest episode of Roll Call on Call of Duty Elite TV.

During the Activision world reveal on May 1st, the company promised that Black Ops 2 would take the Call of Duty series to the next level.

Pushing the boundaries of what fans have come to expect from the record-setting entertainment franchise, 'Call of Duty: Black Ops 2' propels players into a near future, 21st Century Cold War, where technology and weapons have converged to create a new generation of warfare, the site's pre-order page says.

With a Nov. 13 release date, the game is sure to be a hot item on holiday wish lists, competing with other heavy titles such as Assassin's Creed 3 and Halo 4.
