Splicer



"This little fish looks like he just had his cherry popped! I wonder if he's still got some ADAM on him."

- Splicers looking at Jack, searching for ADAM on his body

Splicers are the main enemies within the BioShock and BioShock 2 series. The remains of Rapture's human population, they are the result of the violent conflict during the Rapture Civil War. During this war and the chaotic days that followed, the Splicers apparently murdered most of the sane population of the city. Due to abusive ADAM consumption, their bodies and minds have been deformed beyond repair (though some of their physical deformities can be attributed to Dr. J.S. Steinman's plastic surgery), and they have become dependent on the substance, both mentally and physically. Many of them still wear Masquerade Ball masks, perhaps, as Atlas suggested, out of shame at how ADAM has deformed their bodies.

BioShock
In BioShock, Splicers wander the corridors and the tunnels of Rapture, searching for ADAM, usually in the form of Little Sisters, which often puts them at odds with their Big Daddy protectors—something which Jack can easily exploit to help him survive. Splicers tend to wear very little armor (if any), but they have advanced physical strength and tend to be extremely aggressive in contrast to the calmer Big Daddies. They will sometimes work in groups, use Plasmids and sometimes even play dead to get the advantage on the player.

Thuggish Splicer
The Thuggish Splicer attacks with melee weapons. They can be found throughout the game and are fairly weak, but make up for it by running fast and attacking in groups whenever they can. Later on in the game this Splicer type is more often equipped with the Electric Flesh gene tonic, making them immune to all electrical damage such as Electro Bolt and the Static Discharge Gene Tonic.

Leadhead Splicer
The Leadhead Splicer is still capable of wielding firearms, and attacks with either a Pistol or a Machine Gun. They can also be found throughout the game, but are more dangerous than the Thuggish Splicer since they can attack from a distance. Leadheads will always keep their distance from the player whenever possible, but at very close range they will attempt to pistol-whip them. It is worth knowing that they have to reload their guns, just like Jack, and are defenseless when doing so. They also have more health than a Thuggish Splicer, making them harder to take down, especially if there are more than one.

Spider Splicer
The Spider Splicer is the first Splicer the player sees when they arrive in Rapture, although the player only starts fighting them in Neptune's Bounty. These Splicers can crawl on the ceiling and throw hooks at the player from afar, which can be caught and tossed back with Telekinesis. When on the ground, the Spider Splicer will get near enough to physically attack the player, then immediately jump onto the ceiling or backflip away and come at them from another angle. Their agility and ability to crawl on walls make them difficult to hit, and their modus operandi, which involves ambushing the player by crawling on the ceiling, can easily surprise anyone who is unprepared, although one can easily hear their movement thanks to the telltale sound of cracking plaster.

Houdini Splicer
The Houdini Splicer is first encountered when the player enters Arcadia. These Splicers have the ability to teleport in the middle of combat, disappearing at a location and reappearing at another. They can be tracked through a cloud of smoke that appears around them whenever they do so, which becomes much more visible upon researching this Splicer to the fourth research level. The Houdini Splicer will most often attack by shooting balls of fire (and, in some cases, ice), but like the Leadhead Splicer, will attack physically when at close range. In combat, the Houdini Splicer uses a hit-and-run strategy by appearing, firing an elemental attack, and then vanishing to repeat the cycle.

Nitro Splicer
Nitro Splicers are rarely found throughout the game, mostly in Neptune's Bounty. The first one the player will encounter is in the Medical Pavilion. They will attack by throwing Grenades (and, later, Molotov cocktails) at the player from a distance. At melee range, they will either throw a smoke bomb to the ground, temporarily blinding the player, or they will attempt to flee, tossing an explosive over their shoulder or attempt to kick the player, doing moderate damage. Upon dying, they will drop a live Grenade, with the intent of damaging the player if they were at close range. A common way of killing this Splicer type is by using Telekinesis to catch its grenades and throw them back at it. Researching this Splicer type will increase the chance that their explosives turn out to be duds.

BioShock 2
After ten years of splicing and surviving, Splicers are fewer, more aggressive and much more powerful than those who were encountered in the original game. They are also far more deformed, with their faces often having conformed to the shape of the masks that they used to wear. Their limbs have heavily mutated, becoming lankier and, in some cases, the bone structure actually remodeling itself (such as the development of extra fingers, toes, or even talons). On top of their increased resilience, the remaining Splicers show a twisted form of unity, due to the influence of Sofia Lamb and the Rapture Family. The Splicers loyal to the Family are no longer hostile to Little Sisters, but they see Subject Delta as an enemy and attack him on sight.

Some Splicer models seen in the first game are still present in BioShock 2, such as Leadhead Splicers and Spider Splicers, among other newer or evolved models, now unique to the second game. Splicers are also able to throw grenades while firing their weapons at Delta.

Brute Splicer
A new Splicer type which makes its first appearance in BioShock 2. The Brute Splicer is much bigger, more powerful and bulkier than any other Splicer, and is able to pick up an array of items or debris strewn around Rapture, such as large rocks, and explosives, and throw them at the player. Brute Splicers can also perform staggering jumps several meters in length and height, such as off of balconies, or onto walkways above the ground.

BioShock 2 Multiplayer
As part of the narrative concept of the multiplayer game of BioShock 2, all players take the role of citizens of Rapture who enlisted themselves to the Sinclair Solutions Home Consumer Rewards Program for their own reason. They are testing weapons and genetic enhancement for the firm and conducting trials, which act as field testing on the account of Ryan Industries to test out their newest lines of "home defense" products. However, all those enhancements turn them into Splicer and slowly drive them mad.

Burial at Sea
Most of the Splicers encountered in Fontaine's Department Store are either leadheads or thuggish splicers, But a new splicer type, the Frosty Splicer, has been added. The Splicers that have been locked up in the sunken department store aren't as mutated as those met during and after the civil war, but are showing the trademark mental instability associated with ADAM abuse and  show injuries from fighting against Ryan's forces and each other. Since they were cut off from the rest of Rapture long before the 1958 New Year's party, they lack the distinctive formal masks seen in earlier installments, opting instead to hide their faces with either wooden crates or crudely-drawn paper masks.

Frosty Splicer
Splicers covered in a crystalline, icy shell, they can fire blasts of ice at Booker DeWitt with multiple projectiles. Their transformation is a result of an overdose of the new Plasmid Old Man Winter. The first one is encountered at Rapture on Ice. They are likely immune to frost based (or similar) attacks.

Splicer Models
There are ten Splicer models in BioShock and eight in BioShock 2. Their names are not revealed in-game; instead, they are associated with the sound files used for their sound bites in the game data. The Pigskin, Plastered Splicer, Rosebud, and Waders only appear in the first game. The models that return in BioShock 2 have a more deformed appearance. Additionally, two new Splicer models were introduced with Minerva's Den, the narrative Downloadable Content for BioShock 2. Also, each of those models (with a few exception) feature their own appearance (with some variants in colors) personality and social rank, making them characters on their own.

In the same way as the two first singleplayer games, each of the ten playable characters in BioShock 2 Multiplayer also feature their own appearance and personality, as well as social rank. This and their associated Audio Diaries contribute to telling a different story for each of them.

Behind the Scenes

 * Early in the design process of BioShock, Splicers were known only as "Aggressors".
 * The term "Splicer" is a reference to gene splicing, a natural process that occurs during RNA transcription in cells.
 * Several Splicer models are based on soldiers who sustained horrific facial injuries from the First World War and subsequently underwent pioneering surgery to reconstruct their faces with varying degrees of success.
 * In BioShock 2, there is always one original model and three variations for each of the Splicers' models, plus some variations for specific levels or characters, such as Brute models dressed as orderlies and Toasty models dressed as inmates in Persephone Penal Colony, or Daniel and Simon Wales' Breadwinner and Crawler specific models. Most of these variations, which consist of different clothing, hair and skin colors, are shown in BioShock 2 ' s artbook, Deco Devolution.
 * Each splicer model (with the exception of Heady, Buttons and Crawler) has their own cartoon character which can be seen on Plasimid instruction videos as well as various advertisments.
 * In the Clash in the Clouds downloadable content of BioShock Infinite, completing each of the four levels will unlock at the Columbian Archeological Society a tear to a water puddle, which when activated will bring in a Thuggish splicer bearing the Toasty model and wearing a white rabbit mask. This Easter egg is advertising the next two DLC packs for BioShock Infinite: Burial at Sea - Episode 1 and Episode 2, which take both place in Rapture.
 * In Burial at Sea, the Frosty Splicer uses the same model of the scrapped Vigor Junkie from BioShock Infinite.
