BioShock Endings and Secrets: Little Sisters, Cohen’s Room and More
On this page
Short answer: BioShock’s ending depends on the Little Sisters. Rescue them and you get the good ending, in which Jack takes them to the surface and raises them. Harvest them and you get a bad ending; harvest all of them and the narration is at its angriest. Sander Cohen’s locked room and the “Irony” photo are two more secrets worth knowing.
The endings
| Ending | How to get it |
|---|---|
| Good | Rescue the Little Sisters after beating their Big Daddies. Sources differ on whether harvesting a single one still gives this ending, so rescuing every one is the safe route. |
| Bad | Harvest Little Sisters. |
| Worst variant | Harvest all of them: the same cinematic, with harsher narration. |
Secrets
- Sander Cohen’s room: leave Cohen alive in Fort Frolic. When you return later and kill the two splicers dancing in his apartment, he comes out to fight and his room opens. Killing him early means you miss it.
- Irony: take a photo of Cohen’s dead body for the achievement of that name.
- Free health: hitting a health station with the wrench a few times can knock out free first aid kits.
The series: BioShock, BioShock 2 and BioShock Infinite. More guides: all BioShock guides.
