Bioshock Infinite - Shakespeare Dialogue Hidden in Reversed Audio
April 13, 2013
When you first get the Possession Vigor at the Fairgrounds, a ghostly whisper can be heard. There's no intelligible dialogue, but when the sound is reversed, the whispers turn into several lines quoted from Shakespeare's Romeo and Juliet.
A longer version with some extra lines can be found by extracting the audio from Bioshock Infinite's game files. Part of this is used when you get the Vigor. The rest can be heard being whispered to victims of Possession during combat.
Getting the Possession Vigor:
Romeo and Juliet
Act 3, Scene 2
Come, gentle night, come, loving, black-browed night,
Give me my Romeo. And when I shall die,
Take him and cut him out in little stars,
The lines quoted above are in a different order in the whispers. Setting the Music and Voice volume to zero in the settings makes the whispers heard more easily in the game.
So intentional Easter Egg, or sound guys just having fun again? It could have some deeper meaning than that. When Possession wears off, they kill themselves like at the end of Romeo and Juliet. The Vigor's symbol is also a knife through a heart, like how Juliet stabs herself at the end.
