...a while back there was an interview at the Codex with the sound designers for Myth. In the interview
it is mentioned that there are voices in the graveyard of Silvermines.
I finally just went and extracted them (with the help of The Fallen Sounds) and played them over and over and over and over till they were
superglued to my subconscious.
Indeed, there are several voices in the graveyard (their location
is "rato random tomb" in The Fallen Sounds). Being easter eggs,
the voices have been severely distorted, making it hard to hear
what they're saying.
After helpful e-mails from Geoffrey W. Barnett and Sam Earl all four voices have been deciphered. The voices say:
"Bungie rules the game world"
"Jason" (Jones, Bungie founder)
"Alex" (Seropian, Bungie Founder (thanks to orange for the correction)
"Tuncer" (Deniz, Bungie Production Manager... apparently I've
been pronouncing Tuncer incorrectly, and that's why the voice
made no sense to me)
You can download the sounds in Windows (.wav) or Mac (.aiff) format.
