Throughout Rapture there are numerous holes in the wall surrounded by metallic fixtures. These vents allow Little Sisters access to all areas of the city so they can collect valuable ADAM from corpses. The Little Sisters are the only thing small enough to fit into these vents and crawl through them, therefore they can use them as a means to safely move around the city without a Big Daddy.
Big Daddies are always awake and vigilant. When they do not have a Little Sister with them, they roam to the nearest vent and pound on its rim. The noise summons a Little Sister out. When the Little Sister is tired of or finished gathering ADAM, she goes back to the vent and the Big Daddy usually helps her up into it.
The design of the metallic plate, which includes stylized leaves and plant stems, insinuates that the vents may all lead — possibly through a pumping system — to Arcadia, transporting oxygen and carbon dioxide to and from them. Some areas of Rapture contain vents that are in disrepair with water flowing over or out of them. The Little Sisters were conditioned to use these vents by educational posters in the Little Wonders Educational Facility in Point Prometheus. However, the names of the vents were simplified to seem more innocent and/or friendly, as they are nicknamed, 'Hidey-Holes.'

If the player uses Hypnotize Big Daddy or saves a Little Sister after taking down a Big Daddy, she will scurry back to the nearest vent and crawl away. On levels where Jack has already rescued or harvested every Little Sister, lone Big Daddies roam around and continue to pound on the vents, but no Little Sister comes out. They will show physical signs of aggravation and disappointment, then trudge, in vain, to the next vent.

In BioShock 2, vents are one of the only locations that Subject Delta can directly interact with an adopted Little Sister. After approaching and interacting with a vent, the player is given the option to harvest or save the Little Sister. If she is saved, the little girl will thank Delta for his kindness, climb up into the vent, and disappear.
Throughout Rapture there are many vents which have been decorated as shrines by The Rapture Family. At these locations the Splicers hold services and offer themselves up to the Little Sisters to have their ADAM harvested. Other vents have been decorated by the Little Sisters with crayon drawings. The vents in Dionysus Park, like the one seen to the left, are rusted and covered in barnacles, muck, and starfish.
Vents are how Little Sisters safely travel around Rapture without their Big Daddies.
BioShock 2 MultiplayerEdit

Usually three vents can be found in every multiplayer map for BioShock 2. The vents are only in use during matches of Capture the Sister, which divide the players into two teams, taking turns on capturing the Little Sister from the other team, and returning her safely in to an active vent, while the other team tries to stop them.
Burial at Sea - Episode 1Edit
- Main article: Burial at Sea - Episode 1
In episode 1 of Burial at Sea heating vents take on a similar role to the Little Sister vents. The first of these is seen outside the Little Wonders Educational Facility on Market Street. They are gold painted with a closable grate over the hole.
After traveling to the Housewares department of Fontaine's Department Store, which is now a prison, to find the missing girl Sally, Booker DeWitt and Elizabeth manage to see the girl, fleeing from a Splicer and crawling in to a vent for protection. Elizabeth figures out how to get the girl to them: Closing the vents found throughout the department and turning up the heat will force Sally to come out from one particular vent; the last one to be closed. Apparently, Booker and Elizabeth are not the only one wanting the Sally out: Splicers are trying to lure her out with toys and candy, with no luck.
There's a total of seven vents:
- Tram Station (Closed by Elizabeth)
- The Bistro at Fontaine's
- Customer Service
- Outside Appliances
- Toys (exhaust)
Burial at Sea - Episode 2Edit

Following the end of episode 1, Elizabeth finds herself in dream-like "Paris," which quickly turns into a nightmare after meting Sally. Chasing the young girl leads to DeWitt Investigations, where Elizabeth's conscience takes a toll on her: She is haunted by the memory of her leaving Sally to die in the hot vent, becoming surrounded by several screaming Sallys trapped in the closed vents. Elizabeth then wakes up where the previous episode ended, by the vent in the Toy department, which Atlas and his men has infiltrated. Elizabeth sees Sally being pulled out of the heated vent and manages to compromise a deal with Atlas in exchange for both Sally's and her own life: providing a prison break for Atlas.
