According to some lines of HTML and marketing copy found inside the code on Call of Duty's official website, it looks like Call of Duty: Black Ops 2's next DLC is going to be titled Uprising.
With a leak of this nature, we naturally don't have much information but what we do have is surprisingly descriptive. To start with, a line of code was found that revealed the name 'Uprising', linking to an image with the following bit of HTML:
background: #000 url(‘/content/dam/atvi/callofduty/blackops2/cod-bo2/dlc/dlc2-uprising-bg.jpg’) center top no-repeat;
Naturally, this image link is broken when you complete the link by following the syntax of the rest of the images found on the website.
Thankfully, more information was uncovered from the site, namely this little tidbit:
Download the epic Call of Duty: Black Ops II Uprising Theme, featuring Studio, Vertigo and the Mob of the Dead, Treyarch’s most terrifying Zombies experience to date.
While this alludes to a Black Ops 2 theme on Xbox Live, it's clear that they are also referencing what appears to be two multiplayer maps in Studio and Vertigo as well as Mob of the Dead, which would be the new zombies experience.
Hopefully, Treyarch will roll with this leak and spill some details in the coming days. We'll be here when they do, so check back in with us the rest of this week.
