Out of all of the stark imagery from the "Bioshock" game, the 'Little Sisters' may be the most unsettling. Upon first glance, they appear to simply be generic demon children from your average possession flick, until you notice the fact that they are carrying giant rusty syringes filled with ADAM, the precious genetic material of Rapture. As if the image of a gigantic syringe filled with glowing red gel isn't creepy enough, there's a baby bottle nipple on the end of the ADAM chamber so that the little sisters can imbibe the luminous goo; yikes!
