Call of Duty: Black Ops II -- Revolution Content Breakdown

IGN writes:

"For Call of Duty: Black Ops 2 design director David Vonderhaar, the main creative idea driving the development of the Revolution DLC came down to one thing: diversity. With millions of people logging on to play competitive multiplayer and Zombies every day, Vonderhaar knows it’s up to the team at Treyarch to iterate enough on the experience to keep them hooked, and to make them feel like it’s worth the continued investment."
