BioShock 2 features a morality system centered around your interactions with Little Sisters and other key characters. Your choices directly influence the game's ending. Rescuing Little Sisters (instead of harvesting) and sparing certain characters (Grace Holloway, Stanley Poole, Gilbert Alexander) will lead to a more positive ending for Subject Delta and Eleanor. Conversely, harvesting Little Sisters and killing these characters will result in a darker outcome. There are three main endings: a 'Good' ending, a 'Neutral' ending, and a 'Bad' ending, with slight variations based on specific character choices. If you aim for the 'Good' ending, always choose to rescue Little Sisters and spare the optional characters. Your choices are tracked and will be reflected in the final cinematic.
