Little Sister



"Mr. Bubbles, Mr. Bubbles, are you there? Are you there? Come and give me lolly, come and bring me toffees. Teddy bears... teddy bears."

"Good girls gather, gather......"

Little Sisters are young girls appearing to be around seven years old (perhaps five or six, as their nature suggest), who have been genetically altered and mentally conditioned to reclaim ADAM from the dead around Rapture. Little Sisters are almost always accompanied by a Big Daddy. They are completely immune to damage and have no offensive abilities. Attacking them, however, will incur the wrath of their protector. And like a run-of-the-mill Splicer, exposure to ADAM also drives the Little Sisters completely mad unless they are rescued.

History
ADAM is excreted by a Sea Slug found near Rapture. However, the sea slug did not naturally produce ADAM in large enough quantities for serious research and exploitation. Brigid Tenenbaum developed a procedure whereby a sea slug was implanted in a host's stomach. After the host fed, inducing regurgitation yielded up to thirty times the amount of usable ADAM. Female children were found to be the only viable hosts, and after implantation they were known as Little Sisters. Although Tenenbaum hoped to keep the children in a vegetative state, they had to be fully functional in order to produce ADAM. They still maintained many of the ordinary characteristics of children: laughing, playing, smiling, and singing.

Frank Fontaine used his Little Sisters Orphanage in Apollo Square as a front to obtain a supply of hosts for Tenenbaum. When that failed, Andrew Ryan's men began to take the little girls from their parents directly, promising they would become the salvation of Rapture. Naturally, Ryan told them nothing about the process through which that would occur.

Mental Conditioning
Dr. Suchong, realizing that the need for ADAM was greater than the amount produced by the Little Sisters, pioneered a way for them to recycle Adam from the blood of dead Splicers, greatly increasing their ADAM yield. Naturally, the children were resistant to this demand. Dr. Suchong was able to mentally condition the children to have a neurological impulse to feed and made them associate the bodies of dead Splicers as "angels" to make the process more appealing for the girls. With a physical and neurological drive in place, the Little Sisters now eagerly pursued harvesting of ADAM in Rapture. Like many of the objects in Rapture, the Little Sister's needle was cobbled together out of whatever the makers could salvage: a large needle, a hose nozzle, and a baby bottle in this case.

The Little Sisters were conditioned to see the world of Rapture very differently than the other inhabitants do. Instead of seeing the dark, deteriorated state of the city, they saw an idealized world, with rosy marble floors, pink drapings, and flowering vines growing everywhere. Statues appear as a Big Daddies, and the "angels", which are in reality the dead bodies of Splicers, appear as bodies lying on the ground with the outline of a halo and angel wings surrounding them. Splicers themselves appear as beautiful, elegantly dressed men and women in masquerade masks. However, the little girls world view is brought abruptly back to the grim, twisted reality of Rapture's decay whenever they are frightened or in the process of gathering from a corpse. It is speculated, that flashing back to reality may be a psychological defense mechanism that is activated when threatened by an outside source, or to be able to interact with reality more efficiently.

Pair Bonding
The ADAM coursing through their bodies made them virtually indestructible. However, they still had the stature and strength of small girls. They would be a constant target for abduction and exploitation. Dr. Suchong conceived of partnering each Little Sister with a Big Daddy, a heavily spliced human grafted into an armored diving suit. A pheromone produced by the Big Daddy attracted the Little Sisters, and its counterpart produced by the Little Sisters drove the Big Daddies to defend them with their lives. The first successfully bonded Little Sister was Eleanor Lamb, who paired with the Alpha Series Big Daddy, Subject Delta.

The Little Sisters, because of the pheromone and Suchong's mental conditioning, are strongly attached to the Big Daddies, affectionately calling them "Mister Bubbles" or "Mister B". However, the strong bond between the pairs made the Big Daddies highly aggressive, prompting Ryan to issue public warnings against approaching any Little Sisters. When a Big Daddy is killed, its Little Sisters will stop whatever they're doing and mourn its death.

Curing the Little Sisters
Removal of the sea slug from the host under normal circumstances is fatal. Although the host does not die immediately (their heartbeat can be heard), it was likened to taking a patient off life support: their demise was inevitable. In a forced removal, a large amount of ADAM could still be obtained from the sea slug. However, Tenenbaum's constant contact with the Little Sisters and their unsuppressed childlike behavior eventually caused her to seek a way to safely remove the sea slug. In time, she was able to design a Plasmid to accomplish just that. However, the Plasmid could not reverse the mental conditioning: only time could accomplish that. Tenenbaum established a safe house for restored Little Sisters in the tunnels beneath Olympus Heights for that purpose.

Big Sisters and New Little Sisters
After the events of BioShock Tenenbaum left for the surface, taking many of the saved Little Sisters with her. However, Sofia Lamb soon came into power in Rapture and restarted the Little Sister program to supply The Rapture Family with much needed ADAM and to further her own plans. There were not enough young girls left in Rapture to supply the ADAM cycle, and many of those who remained had matured to the point that they were only useful as Big Sisters. Thus, Lamb began a program of kidnapping young girls from the surface to convert them into Little Sisters. These new Little Sisters developed a unique psychological bond with Eleanor Lamb, who could see through their eyes and control them to a certain extent.

Number of Little Sisters in Rapture
There are a total of 21 Little Sisters which can be rescued or harvested, disregarding any extra Little Sisters which may appear as a result of glitches. If the player harvests all 21 of these Little Sisters, he or she will gain a total of 3360 ADAM throughout the game. If the player rescues all of the Little Sisters, and finds all of the gifts from Dr. Tenenbaum, he or she will earn a total of 3080 ADAM. Accessing the start menu will reveal the number of Little Sisters in the player's current level, as well as their current status.
 * Welcome to Rapture: 2
 * 2 Little Sisters can be seen in one Little Sister Vent each, extremely briefly; and one Little Sister is seen for a moment, but none of them can be rescued or harvested.

 * Only the second Little Sister is protected by a Big Daddy.
 * Neptune's Bounty: 3

Little Sister Rewards
Every three Little Sisters rescued nets the player a reward in the form of a teddy bear clutching a present left at a nearby Gatherer's Garden. The cured Little Sister who delivered the present can sometimes be seen running to the nearest vent.

Strategy
Every three Little Sisters the player harvests will grant them 480 ADAM (160 x 3), whilst every three they save will grant them 440 (80 x 3 + 200), plus many excellent Gene tonics as well as the Hypnotize Big Daddy Plasmid, as well as a bountiful quantity of First Aid Kits or EVE Hypos.

Harvesting represents the short-term solution: Not only will the player end up with more ADAM than if they had saved the Little Sisters, but the first few levels of the game will be much easier to achieve. Coupled with the potential for sampling many different Plasmids and Gene tonics at once, this is the ideal strategy for someone playing BioShock for the first time. This path unlocks the unhappiest ending to the game.

Saving, on the other hand, is a long-term investment. While it is harder to survive the first few levels with this path, it ultimately offers greater rewards. The gene tonics and Plasmids the player receives are among the most powerful in the game and cannot be obtained otherwise. The ADAM gap between a Harvester and a Rescuer (280 ADAM in total) is also compensated by these bonuses. However, these rewards may or may not suit one's playstyle (due to the benevolent nature of Dr. Tenenbaum, all of these rewards offer non-aggressive boons), so it is recommended to either look up the rewards individually or play the game as a Harvester first. This option is recommended for experienced players or for those who have already played the game. This strategy will also unlock the happiest ending in the game.

Mixing both strategies is not excluded. By both harvesting and saving the Little Sisters the player offers themselves a generous dose of ADAM, with unique Plasmids and Gene tonics to boot. Please note that the player only gets their rescue reward after saving three Little Sisters, so if one is feeling scrupulous do so in blocks of three so as to get that reward as quickly as possible. Also note that this strategy will never get the player as much ADAM as a pro-Harvester, nor as many unique rewards as a pro-Rescuer. However, with efficient planning and harvest/rescue alternation one can combine the advantages of both paths, making one's life easier during the first stages of the game while being able to use a Big Daddy as a bodyguard. This option can be taken by any type of gamer, regardless of their skill or experience level. This path will also offer the player a unique ending to the game, similar to that of the Harvester ending but less miserable.

BioShock 2


In BioShock 2, the tactics of gaining ADAM are very similar to the first game. Once the player comes across a Little Sister, they can either Harvest her, or Adopt her. It should be noted that a Little Sister rarely carries much ADAM when first met. Instead the player can put her on their shoulders and look for an ADAM-rich corpse. This will attract the Splicers' attention, forcing the player to set up a perimeter. Once she has harvested the ADAM, the player will have two choices. They can either send her to a Little Sister Vent back to Tenenbaum or they can harvest her, as she will contain a lot more ADAM after gathering. The Little Sister will give the player ADAM every time she harvests a Splicer.

This system is meant to be an even harder choice for the player, since the potential gain from harvesting is much greater. However, by saving little sisters, the player can earn a present, including a Gene Tonic called Proud Parent, increasing the ADAM harvested per corpse by 20, and the Demanding Father tonic that increases the speed at which the Sister gathers ADAM.

Storyline
To acquire a Little Sister her Big Daddy protector must be killed first. Afterward she stalls for a few seconds then replies to the player "Mister... Mister B? It's you, you're all better again!" This is due to Eleanor Lamb's psychological affinity to the player (Big Daddy). Being the first Little Sister (in addition to her ADAM augmentation), Eleanor Lamb possesses a psychological link between all Little Sisters. This allows Eleanor's affection to the player transfer over to every Little Sister and allows the player to adopt any Little Sister in Rapture.

Near the end of the game, Delta is captured by Sofia Lamb and is immobilized. To help him escape, Eleanor Lamb sends a Little Sister to him with a plasmid to take control of her. Upon the Little Sister injecting Delta with the needle, the player will take on the viewpoint of the Little Sister. During this, the whole level will look pristinely beautiful, since the Little Sister's mental conditioning affects her perception of the world around her. The nightmarish prison cells and environment will be completely replaced by spotless white curtains and plush red carpeting. Splicers will be replaced by masked men in tuxedos, blood stains by flower petals, etc.

Additionally, to the choices the player has made throughout the game,the Little Sister may see different statues throughout the level depicting Delta's actions. The only times the view will show the level how it actually is is when harvesting, moving toward a Splicer held in a cell, picking up parts of a Big Sister suit, and heading back to where Sofia Lamb was. Once Eleanor has been given suit parts, she will save or harvest the Little Sister Delta was controlling (depending on the player's actions towards the Little Sisters), returning him to his body.

The players choice of whether to save or harvest Little Sisters affects the ending of the game and how Eleanor treats the other Little Sisters.

Little Sister Rewards
A reward is hidden in a teddy bear at a nearby Gatherer's Garden for every 4 sisters rescued. A bug sometimes prevents the Little Sister from moving away until Delta is right next to her. There are three gifts total, each granted after four Little Sisters have been saved.

Strategy
While the harvest/save dilemma is still present in the sequel, a new mechanic is introduced: adoption. This section will cover the latter strategy. For information on the two other mechanics, see the previous section.


 * Each Little Sister can harvest up to two corpses each. Since ADAM is the most precious resource in the game and can only be found in (very) limited supply, it is heavily recommended to have the Little Sister harvest as many corpses as possible.


 * Each successful harvest yields 40 ADAM, meaning the player can harvest up to 80 ADAM per Sister by adoption alone. Use of the Proud Parent Tonic increases the gain from 40 to 60 ADAM per corpse, the final amount given upon harvesting or rescuing the Little Sister is unaffected.


 * When having spotted a corpse, secure the entire area: hack every machine, equip the right gene tonics] (especially [[Proud Parent and Demanding Father, if the player has them), fill up on ammo, health and EVE, and buy enough First Aid Kits and EVE Hypos to be able to wage a small war. Having done that, take note of all the passages that lead to the corpse and devise an adapted battle plan. Next up, lay traps (Trap Rivets, Trap Spears, etc) on those passages and around the corpse. If one has any Miniature Turrets, deploy them too. If the player considers themselves sufficiently prepared, signal to the Little Sister that she can start harvesting.


 * Upon adopting a Little Sister, an icon to the middle left of the HUD will indicate the Little Sister's status: if the Little Sister is on Delta's shoulders, the icon will show a Little Sister standing in front of a Big Daddy. When the Little Sister starts harvesting, a progress bar will appear, showing how much time the player has left before the Little Sister will have finished extracting ADAM from the corpse (thus ending the waves of Splicers). When harvesting, the icon will change to a Little Sister sticking her needle into a corpse. If the Little Sister is being assaulted by a Splicer the icon will change to a vivid exclamation mark, and the progress bar will pause until the Little Sister is freed from her aggressor.


 * The best form of weaponry when dealing with multiple waves of Splicers, besides traps, is ordnance and plasmids capable of dealing very quickly with several enemies, for example the Machine Gun or the Launcher. However, it is recommended to conserve resources and use the cheapest ammunition types if possible.


 * In BioShock 2, a Rescuer can gain up to 3180 ADAM (assuming the player follows the full adoption routine for each Sister and collects every Sea Slug) while a Harvester will earn a total of 3320 ADAM, creating a gap of 140 ADAM. In the long run, this means a Harvester will be able to buy more and better plasmids, although a Rescuer will be better sticked up on resources and will have the Demanding Father tonic to boot. However, the difference isn't as marked as in the first game, and both alternatives here are equivalent.


 * If one chooses to harvest the Little Sisters after obtaining the Proud Parent gene tonic, one will earn a total of 3520 ADAM, 200 more than what a pure Harvester would receive, coupled with a few extra resources. However, doing so will prevent the player from earning the Demanding Father tonic. In the long run, it is better to save the first four Little Sisters and then switch to harvesting them, rather than do the latter from the start.

BioShock 2 Multiplayer
In the Multiplayer, Little Sisters feature in several game modes as a capturable objective.

Bugs/Glitches

 * In the PC version 1.0 of BioShock 2 if the player chooses to bind a different key for "use" they will still be prompted to press the original "use" key when adopting a Little Sister, but this will do nothing. Pressing the key that has been re-bound to "use" will allow the player to adopt a Little Sister.

Trivia

 * Originally the Little Sister could be killed by physical damage. Presumably due to the difficulty the AI had in keeping her alive she is nearly invulnerable by the final game. It is stated in an Audio Diary, that the Little Sisters are invulnerable to damage due to the regenerative ability of the Sea Slugs within them. This explains why they cannot be hurt by the player or other splicers. However, the little girls will still be immune to damage even after they have been rescued by Jack. Attempting to harm them as they run to the nearest vent will have no effect, possibly due to residual ADAM still in their bodies. In BioShock 2 a Little Sister will glow an unnatural golden color if struck by the player, showing the effects of regeneration, but will otherwise give no reaction.


 * The "Little Sister" seen in the BioShock X06 Trailer features little to none of a Little Sister's characteristics, besides her ADAM extractor. This is most likely because the teaser presented content that was still under development.


 * There are three corpses of little girls found in one of the Mercury Suites apartments in BioShock. Each of these little girls are actually reused rescued Little Sister models. Interestingly, they are not affected by Telekinesis.


 * In Cohen's Collection in Fort Frolic, there are many plaster-coated figures sitting at a table including plaster-coated Little Sister models. However, these are actual statues rather than real Little Sisters, as they produce plaster when hit instead of blood.


 * When Jack first approaches the Little Sister Vent found in the Kashmir Restaurant, he can catch a glimpse of glowing eyes. The same thing occurs to Subject Delta when he first awakens in the Adonis Luxury Resort with the first vent he comes across.


 * Originally, the player was to collect ADAM directly from the sea slugs that produce it. However, the developers wanted to give the choice of harvesting ADAM more impact, so the host design went through many changes, including a small chipmunk like creature (like in the Utropolis story), but the effect was deemed too comedic. The concept of Little Sisters stemmed from the need to find a more empathetic victim for the player.


 * There is a slight discrepancy in the method of recycling ADAM from dead bodies. In theory, Little Sister would have to drink ALL the body fluids of a corpse in order to recycle all the ADAM. However it is observed that the Sisters stab the corpses in a random place with their needles and only extract a small amount of fluid. There is a possibility that ADAM is stored in a specific place or organ of the human body that only Little Sisters can find. The Spider Splicer's organ, an item that can replenish health, could be an example of said organ.


 * In BioShock 2 the Little Sisters are voiced Jodelle Ferland (who is much closer to the apparent age of the Little Sisters) with a distortion effect.


 * Using noclip (with console commands on the PC), it is possible to see and explore the Persephone level in nightmare/brainwash mode as the Little Sister in BioShock 2. Not all areas that are rendered in the brainwashed world have a nightmare equivalent however, for example near Sofia's desk, there is no actual switch to be flipped to unlock the doors.


 * As revealed in the level Persephone, Little Sisters see their Big Daddies refashioned to resemble Golden Knights. They see Big Sisters as Brides or Princesses. When playing as Little Sister, if the player stays several feet away from the Big Sister Parts, the player can see the parts as Little Sister's see them. The Big Sister's suit will appear as a large dress, the Helmet as a veil, and the gloves as long, elegant ballroom gloves.


 * All Little Sisters are barefoot. While probably a means of lowering production costs on Little Sisters, since Little Sisters are nearly invulnerable passively, they should be able to walk on anything without problem.
