Trivia
The Rumbler type of Big Daddy in this game is a revision of the SLOPRO Big Daddy which was cut from the first game. The initial concept for the character had the shoulder mounted cannon as seen in BioShock 2 but instead of being able to set up mini turrets, the SLOPRO held a massive hook which it used to perform lethal melee attacks.
Sheryl Lee was hired for the recording session by accident, due to some mix up with the auditions. She plays one of the Splicers standing around a fire discussing what happened to Jack near the start.
Eleanor Lamb: [final lines]
If utopia is not a place, but a people, then we must choose carefully; for the world is about to change... and in our story, Rapture... was just the beginning.
Grace Holloway: You had me under a gun... and yet you just walk away? No monster alive turns the other cheek. No monster does that. A thinking man does that.
