The Demonic Announcer is not fully included (except Fire Sale and Death Machine) in the German, Austrian, French, Spanish and Russian versions of Black Ops. However, upon completion of the Richtofen's Grand Scheme easter egg, she appears for the rest of the playtime on Moon.
The Demonic Announcer is only present in the revamped World at War maps in the French, Italian, Spanish and Russian versions of Black Ops.
In the French, Portuguese and Spanish versions of Call of Duty: Black Ops III, the Demonic Announcer on both The Giant and Shadows of Evil is Edward Richtofen instead of Samantha Maxis.
The eyes are yellow in Shadows of Evil, Der Eisendrache, and Zetsubou No Shima, despite Samantha not controlling the zombies as of Origins.
The Crusader Zombies have white/purple eyes in the Origins cutscene. However, their eyes are blue in-game.
In the Call of Duty: Black Ops III version of Origins, the Crusader Zombies now have yellow eyes like the rest of the normal zombies, implying that they canonically did not have a different eye-color, despite being portrayed as such within Call of Duty: Black Ops II.
Maxis remains silent when players pick up Power-Ups.
