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. The controller of this map is unknown, though when Richtofen turns to the announcer he speaks to Samantha.
In Origins, although Samantha talks to the characters in Origins, Richtofen claims several times that Samantha is not who she really is. For example, he says that "I do not intend to follow my former friend into insanity. Besides, I know what you really are, Samantha", and "My companions may be easily manipulated, I will not, I know what you really are.".
Treyarch's Origins intro cutscene has Samantha's voice completely demonic, supporting Richtofen's claim on the announcer identity. Samantha has a similar demonic voice when she gives power ups, during the Moon Easter egg, as well as Origins' zombie blood whispers.
The Crusader Zombies that spawn in main chamber have bright 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, which may imply that they canonically did not have a different eye-color, despite being portrayed as such within Call of Duty: Black Ops II.
During the last step of the Shadows of Evil easter egg, the color of the Margwa heads turns from yellow-orange to purple, suggesting someone else controls the Margwas.
In TranZit, Richtofen has special announcer quotes that appear only in the first game of the player. On console, they can also be heard upon playing on the "Local" mode. One of the most notable quotes play when the player picks up a power-up for the first time, to which Richtofen replies instead of the standard power-up name: "*Demonic scream that fades into Richtofen coughing* Excuse me, just getting used to the Aether, plays havoc on the pipes, ah.. right.".
In Buried, Maxis remains silent when players pick up Power-Ups. Similarly, when the Mystery box moves, the usual "Bye-bye" greeting cannot be heard, and only Samantha's demonic laugh can be heard.
