On Richtofen's page in the Call of Duty Wiki, someone claimed that while playing him on Ascension, you can actually hear voices, or a single voice, that whisper to him. The voice allegedly sounds like Richtofen. Presumably this isn't something you can hear while playing the other three characters.
The Wiki is probably one of the least trustworthy places to get information on Zombies for various reasons, one being that people have posted random, false, and, honestly, idiodic things in Trivia sections before. Not to mention, hearing Richtofen's voice while playing as him is far from unthinkable.
However, this was an interesting enough tidbit to warrant further investigation. Does anyone know anything about this? Or can anyone with a 360 try playing Richtofen on solo to see if you can hear anything?
The exact quote from the page goes: "In Ascension, it is possible to hear the voices in his head as when you play as him, the player might hear a whispering voice similar to his own telling him things."
Thank you for your time.
