Trivia

 * In Nuketown Zombies, some zombies can be seen eating the dead body of a CDC agent or they appear as zombies.
 * The Nuketown Zombies trailer depicts four CDC operatives fighting the zombie horde, interestingly, they are heard speaking, unlike the actual map, where they are silent unless the knife attack is used. Furthermore, the four operatives are seen with different voices, as if they were meant to speak, but it was cut out.
 * Furthermore, the trailer does not depict the CIA agents that are also present in the map.
