According to Treyarch's lead designer Mark Lamia, the list of consultants and writers enlisted by Treyarch to take on the continuation of the Black Ops series will be more than ever, including David Goyer, the man behind the Joker in The Dark Knight, and Black Ops director Dave Anthony.
- "And it’s Black Ops 2, and with Black Ops, we really wanted to make sure that the historical fiction was plausible so we could just set you in that, and then we tell our story and let you play through our fiction. We took that exact same approach with Black Ops 2. To do that, we enlisted some experts, the kind of experts that advise world leaders right now on what they should be concerned about in the next decade."
Goyer was credited with helping to create Heath Ledger's the Joker in The Dark Knight, and saw the importance of creating a three-dimensional villain character. However, as he was only enlisted to help with the first game halfway through production, he instead rather proofread the story instead; this time he was able to write the story for Black Ops 2 from Day 1, meaning he'll have a more direct influence on the script.
- "[Goyer and Anthony] were so excited and so energized about the characters and the story that we created and the fiction we created for Black Ops, and they wanted to kind of push it forward, and they wanted to work together again on sort of rewriting the book on how we tell stories in Call of Duty and Black Ops," Lamia stated.
Oliver North, retired U.S. Marine and best-selling author, lent his expertise to advise Treyarch for Call of Duty: Black Ops 2. North was at the center of Iran–Contra affair in the late 1980s, so will no doubt be able to advise Treyarch on where to take players into the darkest stories of the U.S.'s conflict with the forces of Communism. In the 80's North lead the mission to hunt down those responsible for the 1983 Beirut barracks bombing and then in 1986 he helped carry out the invasion of Grenada and bombing Libya, so he'll definitely have a plethora of experiences to share with the developer.
