Central Intelligence Agency/Zombies

In Call of Duty: Black Ops II during the Grief mode of Zombies, they are in conflict with the CDC for survival after the aftermath of Richtofen's Grand Scheme.

In the Zombies mode of Call of Duty: Black Ops II there is no heard quotes or communication between the 4 operatives.

They appear as men in black suits heavily resembling the SSA seen in the Black Ops campaign mission U.S.D.D.

None of the CIA or CDC Operatives in Nuketown Zombies, Town or Farm survived the hordes of zombies (Unless playing on Grief).

Trivia

 * In Zombies, they will sometimes hiccup instead burping when drinking perks.
