- "Seems like some poor blighters have started seeing ghosts. Ghosts! Ryan tells me it's a side effect of this Plasmid business. One poor sod's memories getting passed on to another through genetic sampling. Leaks. Lunatics. Rebellion. And now bleeding ghosts. Ain't life in Rapture grand?"
- ―Bill McDonagh[src]
Ghosts are the leftover memories caused by a crossover of genes during genetic sampling, caused by the use of recycled ADAM harvested from corpses by Little Sisters. Ghosts feature prominently in the story of BioShock, and are sometimes equally as important as Audio Diaries. They are also a way of displaying to the player the exact repercussions caused by excessive use of ADAM.

Behind the ScenesEdit
- Although BioShock 2 does not feature ghosts as portrayed in BioShock, the launch trailer for BioShock 2 does contain a scene featuring a large assortment of ghosts dancing. As revealed by BioShock 2 Creative Director Jordan Thomas in an interview with GamesRadar, the idea of ghosts and genetic memories would have originally played a larger role in BioShock 2 as more than just cutscenes: "There were a number of playable flashbacks, which had a prequel-like flavor, but were much more subjective, like memories that you were uncovering. But they were terrible. What Rapture was like in its heyday appeals on paper, but it meant you really couldn’t play the game. Players sleepwalked through each scene, which was pretty, but not particularly convincing."
- A removed "Eleanor vision" that is still present in the game files reveals that the developers at one point intended Subject Delta to be Eleanor's actual biological father. It would have stated that Sofia Lamb bought Delta's DNA while he was imprisoned in Persephone. Sofia did not explicitly choose Delta; she simply needed the seed by which she could make Eleanor.
- However, another unused file shows they also planned to make it clear she was not Delta's daughter. 
- The second memory seen after dealing with the second Little Sister in Dionysus Park is flawed. It starts showing a regular Little Sister, supposed to be Eleanor, and ends using Eleanor's actual child model.
- BioShock shares similar ghost apparitions with System Shock 2, Irrational Games' first game and the spiritual predecessor of BioShock. The reason for their apparitions aboard the Von Braun starship are however due to the protagonist's cybernetic implants, which like Plasmids upgrade his abilities. Also on the Medical Deck, a ghost is seen banging at a locked door, begging to be let in, just like at the Medical Pavilion in BioShock.
