All surgery requires a set of medical tools, typically found in the Operating Theatre, along with an operating table. Should the surgery tools be missing, more can be printed from the techfab in Medbay Storage.

Surgical Tools

Information about every tool used in surgery can be found here.

For every tools there are ghetto analogues. Using them lowers chances of performing a surgical step correctly, wounding your patient. Hover your cursor over the item's picture to see its name. Next to the items are the success rates.

Surgery Success Chances

Surgery success chances follow the following formula: (Surface + Chem) * Tool Success Chance

Surface refers to the surface the surgery is taking place on, whether it be an operating table, a bed or even the floor. The highest value will be used when multiple are taken into account (ex: Surgery done to someone on a tile with both a table and a bed will take the table's 80% over the bed's 70%. This applies even if they aren't buckled to the surface).

Chem refers to any applied chemicals applied via touch, vapor, or patches to the patient during the surgery (IV injecting a chemical or injecting it with a syringe will not count towards this value). This will not stack, and will only choose the highest applied chemical value.

Tool Success Chance is the chance of success intrinsically tied to a given tool. Surgical grade equipment is generally the best, and ghetto analogues are generally discouraged unless very desperate.

Beginning of any Operation

Step 1: Place the patient onto the operating table (or have them just climb onto the table). Do this by ctrl + clicking them twice to aggressively grab them. Then left click the operating table to place the patient on it. Be sure to turn combat mode off or your surgery will fail.

If there is no operating table, you can use: stasis bed (100%), any table (80%), any bed (70%), ask them to lie on the floor (50%). Operating tables give a 100% surface value.

Step 2: Exposed the patient's appropriate body part. This could vary from simply having the patient take off their headwear, to having them fully strip (This can be performed at any point in the surgery prior to Step 7, but it's faster that they strip rather than have you slowly strip them).

Step 2: Sedate the patient using a tank of anesthetic and any breath mask or inject them with Morphine. Keeping your patient awake for most surgeries will result in a 50% (100% if the step is failed) chance to cause a minor screw-up, causing damage and a chance for bleeding depending on how intensive the surgery step is. Pain killers such as (and currently only) Miner's Salve and the alcoholic drink Painkiller reduce the chance by half, and being unconscious for any reason reduces it by a fifth. Getting your patient drunk will also offset the slip-up chance depending on how drunk they are. If the patient has a disease containing the symptom Analgesia or the brain trauma Tenacity, they will count as being fully anesthetized.

Step 3: Ensure combat mode is off

Step 4: Aim at the appropriate body part (important!).

Step 5: Click on the target with the tool that is used in the first step of the operation. For example, use the scalpel to begin organ manipulation.

Step 6 (optional): (Optional) Splash on, spray or apply a patch with Miner's Salve (+10%), Sterilizine (+20%), alcoholic drinks (up to +46%), or Honey (+60%) to improve your success chance. This must be done after the surgery has been chosen or during the surgery itself in order for the bonus to be considered.

The stronger the alcohol, the more effective! The formula is: 0.1*(booze power/65). For example: Ethanol gives +10% success chance, Manly Dorf +15%, Bacchus' Blessing +46%.

Step 7: Do the surgery (see the steps below!). Afterwards congratulate the patient and kick them out.

Note that increases from the surface used and chemicals applied are multiplicatively applied to a tool's success chance, so adding sterilizer for a 20% success bonus while operating on an operating table or stasis bed will increase a tool's success chance from for example 80% to 96% rather than 80% to 100%.
Success boosts from chemicals additionally will not stack with other chemicals, only the highest increase is applied.

To abort a surgery, use the cautery in hand.

Procedures requiring no research or computer

Organ Manipulation

This surgery covers operations to remove/insert organs (brain, heart, appendix), lizard/cat tails, cyber implants and alien embryos.
The body part to target depends on which procedure you want to do.
See below for details about each procedure.

Procedure	Ghetto Analogues
Step 1: Scalpel: Make an incision	(75%) (65%) (45%) Any other sharp item (30%)
Step 2: Retractor: Retract the skin	(45%) (35%)
Step 3 (Head/Chest only): Circular Saw: Saw through bones	(75%) (65%) (50%) (50%) (35%) (25%)
Step 4: Hemostat: Clamp the bleeders	(60%) (35%) (15%)
Step 5: Scalpel: Make an incision	(75%) (65%) (45%) Any other sharp item (30%)
Step 6 Remove: Hemostat: Remove something	(55%)
Step 6 Insert: Hands: insert something
Step 7: Cautery: Seal the wound	(90%) (70%) Any other hot item(30%)

Ordinary organs that require Organ Manipulation

These organs are present in every normal human, and can be removed or transferred through the Organ Manipulation surgery type.

Brain

The source of consciousness, and where the player actually resides. Removing the brain from a body will make it unclonable through normal means. The brain can also be inserted into an MMI to allow it to speak, and to prepare it to be inserted into a Cyborg or an AI. Or it can be transferred into another body, which can then be cloned or defibrillated with the new host.

Changelings' brains are vestigial, and they can survive without them. Beheading a changeling will not prevent one from reviving.

Target: Head

Note: Brains can also be removed by beheading the target and using a sharp object on the head to extract the brain.

Note: There's also a non-surgery method to put a brain back in:

Step 1: Place the patient onto the operating table.

Step 2: Cram their brain back into their skull.

Step 3: Usually, you take the body to be cloned (this can be done without step 2).

Heart

Required for basic survival, removing it will cause a heart attack, dealing huge amounts of oxygen damage until a new, beating, heart is inserted, or death. This can be delayed with epinephrine, if you need more time.

On their own, hearts only beat for a short time when removed from a living body. To get a heart beating again, click on it while it's in your hand.

Heart attacks can also be induced by initropidril, and a heart attack may continue if you insert a still heart in a patient. In either case, to restore the heart to normal functionality, the patient needs to either be defibrillated or receive an electric shock. Target: Chest

**Heart Variants**
Name	Icon	Description
Cursed Heart		Provides a powerful regeneration effect to the host, but comes at the price of needing to be pumped manually, or else they begin to suffocate.
Heart of Freedom		When the user falls to critically low health, will heal a small amount of brute and burn injuries across the body, and also add ephedrine to the user. This effect has a random cooldown between 4.5 and 10 minutes. Often found after a Meat-eor storm event.
Maintenance Heart		Half as durable as a regular heart, and half as effective in generating blood. A terrible replacement option, but will keep someone alive in an emergency.
Cybernetic Heart		Functionally identical to a standard organic heart. Suseptible to EMP
Upgraded Cybernetic Heart		When the owner falls unconscious, will inject 10u of epinephrine. This effect has a 5 minute cooldown. Suseptible to EMP, but capable of restarting itself after.
Nanite Heart		Functionally identical to a standard heart, but with the added benefit of increasing nanite generation in the host. However, if the host's nanites are depleted, the heart will collapse entirely, resulting in a rapid death. Suseptible to EMP by way of harming nanites in the host.

Eyes

They're required for sight; removing them will, obviously, turn the patient blind. Some races' eyes can see in the dark.

Target: Eyes

**Eye Variants**
Name	Icon	Description
Mothman Eyes		More susceptible to flashes than other races.
Polysmorph Eyes		Slightly better at vision in dark environments than other races.
Flashlight Eyes		Basically just flashlights for eyes, provides toggleable light, but good luck seeing anything. Susceptible to EMP.
Robotic Eyes		Functionally identical to standard human eyes. Susceptible to EMP.
Preternis Eyes		Possess a night vision mode toggleable while in good condition, deteriorate when in a non preternis and heal themselves when in a preternis. Susceptible to EMP.
Thermal Eyes		Able to see living creatures through walls, but not the layout of the area they're in. Susceptible to EMP and more vulnerable to flashes.
X-ray Eyes		Effectively gives the wielder true sight, being able to see people, objects, and turf through walls. Susceptible to EMP.
Meson Eyes		Gives meson vision, letting the user see the layout of walls and floors around them through obstacles and in the dark, also protects the user from the hallucinations of the Supermatter Crystal. Susceptible to EMP.
Welding Shielded Eyes		Standard eyes with the added benefit of being flash proof. Susceptible to EMP.
Luminescent Eyes		Identical to robot eyes but glow extra bright. Purely for cosmetic showing off. Susceptible to EMP.

Ears

They're required for hearing

Target: Head

**Ear Variants**
Name	Icon	Description
Cat Ears		Take twice as much damage from loud noises.
Penguin Ears		Forces the host to waddle, rather than walk normally
Cybernetic Ears		Offers 20% more protection from loud noises.

Lungs

Required for breathing. Removing the lungs will cause the patient to suffocate, regardless of air or internals. Some species have mutant lungs that don't need air: transplanting them onto an breathing race will transfer this property.

Target: Chest

Lung Variants
Name	Icon	Description
Plasmaman Lungs		Unable to breathe regular air, needs plasma.
Polysmorph Lungs		Able to breathe oxygen and plasma, but take damage from hot gasses at lower temperatures than other lungs.
Preternis Lungs		Can safelty breathe air that's thinner and handle small toxin content in the air before taking damage. More sensitive to cold and hot gasses. Not sensitive to EMP.
Mesophyll		Able to breathe oxygen and CO₂, taste like fruits and veggies.
Aeration Reticulum		Able to breathe water and convert it into hydrogen and oxygen.
Grey Lungs		Breathe nitrogen instead of oxygen. Able to breathe the standard air mix for it is composed at 80% of nitrogen.
Ghetto Lungs		Half as durable as regular lungs, but will allow someone to breathe.
Extended Lungs		Half as durable, twice as efficient, but require twice as much air pressure to breath properly. These lungs are the result of performing the illegal and dangerous operation of using a crowbar on lungs to extend them.
Cybernetic Lungs		More durable than standard lungs and can breathe air that's thinner safely. Susceptible to EMP
Upgraded Cybernetic Lungs		Twice as durable as standard lungs, able to safely function with an air content as low as 10 psi, able to handle both colder gasses as well as hotter before taking damage, and able to handle a substantial toxin content in the air before taking damage.

Liver

Processes reagents in the body. Without this, you can't process any reagents, and even worse, you can't get drunk. Taking toxin damage or binge drinking will damage this organ.

Target: Chest

Liver Variants
Name	Icon	Description
Flyperson Liver		Slightly worse at handling alcohol than a human liver.
Polysmorph Liver		Takes 2.5x damage from toxins, but filters them much more efficiently.
Cybernetic Liver		Marginally more health than a human liver, handles toxins more effectively and filters them quicker, and takes less damage from alcohol.
Upgraded Cybernetic Liver		1.5x health compared to an organic liver, better toxin tolerance and filtering, better alcohol handling, and provides passive toxin damage healing.

Stomach

In charge of telling you when you're starving or stuffed. Handles the processing of nutriment to make a spessman full and happy.

Target: Chest

Stomach Variants
Name	Icon	Description
Ethereal Stomach		Rather than standard food, Ethereals need electricity to sustain themselves. Be it from borg chargers, capacitive cell plants, or literally being electrocuted (although this will still hurt).

Cursed Stomach		Gives the owner the ability to vomit on command and vomitcrawl. Sink into a pool of vomit and freely move around, but you must resurface at another pool of vomit. Disgusting, but powerful.
Cybernetic Stomach		Slightly more durable than a standard stomach. Reduces disgust 20% faster than a normal stomach.
Upgraded Cybernetic Stomach		Twice as durable as a standard stomach and able to stash nutriment inside itself while processing food to feed the host later when they become hungry. Reduces disgust 100% faster than a normal stomach.

Tongue

Affects speech. Lacking a tongue will make speech very hard to comprehend, while mutant tongues such as lizards' or flypeoples' will give the patient the race's speech quirks. Abductors' tongues carry over their telepathy, but they prevent normal speech.

Target: Mouth

Tongue Variants
Name	Icon	Description
Lizard Tongue		Makes the host hisssy.
Polysmorph Tongue		Also hissy, but capable of the real Xenomorph language.
Abductor Tongue		Lose the ability of spoken language, but speak silently through a network of other people with Abductor Tongues. Does not allow you to hear active Abductors however, as they are on a different network!
Snail Tongue		Your words are going to take a while to say.
Zombie Tongue		Makes speech slow... slurred... and occasionally forces the user to moan about Braaaiinnnsss.
Bone Tongue		Clatter and rattle your words in a special papyrus font.
Xenomorph Tongue		Growl out all your words like a real Xenomorph!
Robotic Voicebox		Effectively a cybernetic tongue. Capable of all languages (provided you know them), but your speaking verbs become monotone like that of a robot. Also, you can't taste as well.

Appendix

Removing it cures appendicitis and prevents it in the future, too.

Target: Groin

Other organs that require Organ Manipulation

There are also non-natural organs which can be added to give bonuses or to harm the patient in a few cases.

Cybernetic Implants

These offer benefits to the patient at the cost of being very vulnerable to EMPs, with malfunctions ranging from eye-flashing to heart attacks. Cybernetic implants always require the Organ Manipulation type surgery, even for arms. Cybernetic implants can be printed by Robotics or the medbay techfab after research.
Target: Chest/Head/Eyes/Arms/Legs

Table of Often Available Cybernetic Implants
Implant	Implant Region	Description
Anti Drop Implant	Target: Head	Gives the user a toggleable button capable of determining whether they can drop and item or not.
Anti Stun Implant	Target: Head	Greatly reduces the severity of all stuns on the user.
Med/Sci/Diagnostic HUD Implant	Target: Eyes	Eye implants that overlay their corresponding HUD elements without the need for eyewear.
Chemical Analyzer Implant	Target: Eyes	Allows user to identify reagents in a container by examining it without the need for science googles.
Breathing Tube Implant	Target: Mouth	Adds an internals connecting port to your back, protecting you from being strangled and allowing you to use breathing tanks without a mask.
Nutriment Pump Implant	Target: Chest	Automatically feeds the user when they reach the hunger state of starving, but they will still get hungry.
Nutriment Pump Implant PLUS	Target: Chest	Automatically feeds the user when they become starving, removing the need for eating.
Reviver Implant	Target: Chest	When the user falls into an unconscious or soft critical state (between 0 and -30 health), the implant will attempt to revive them by patching their wounds. Additionally, this implant will also stop heart attacks in the user.
Implantable Thrusters Set	Target: Chest	Effectively an implanted jetpack that works in zero-gravity environments. If there is at least 30 kpa in the surrounding atmosphere, the jetpack can function without any input. However in a vaccum it will still require internals to run off of. Susceptible to EMP
Surgical/Toolset Implant	Target: Arms	When implanted, will give the user access to a full set of fast tools. The tools available are dependant on the type of implant. Only one toolset implant per arm. A screwdriver can toggle the arm configuration of the toolset. By default, the implant is designed for the right arm.
Slip Resistance Implant	Target: Legs	When implanted, grants resistance to water slipping. More significant slips, such as lube, will still affect the user. Requires the implant installed in both legs to function. Only one implant per leg.
Jumpboots Implant	Target: Legs	When implanted, permits a rapid dash forward with a minor cooldown. Can crash into people or walls with the dash. Requires the implant installed in both legs to function. Only one implant per leg.
Wheelies Implant	Target: Legs	When implanted, will permit you to enter WHEELIE mode and zoom around the station like you're on a skateboard, but without the board. Requires the implant installed in both legs to function. Only one implant per leg.
Magboot Implant	Target: Legs	When implanted, allows activation to render stable movement in zero-g environments. Preterni inherently have this built into their chassis, though it does not count as an implant. Requires the implant installed in both legs to function. Only one implant per leg.

Cybernetic Organs

Cybernetic organs replace organs entirely. You need to remove the corresponding organ first to make room for the cybernetic organ. They are vulnerable to EMPs. Cybernetic organs can be printed by Robotics or the medbay techfab after research.

Target: Chest/Eyes

Xenomorph Embryo

An alien larva growing inside the patient. If not removed quickly enough, it will gib the patient and try to escape, growing into a dangerous Xenomorph.

Target: Chest

Plasma Vessel

Target: Chest

Romerol Tumor

A latent infection in the patient's head, caused by Romerol. If the patient dies while affected by Romerol, he will eventually rise as an aggressive Zombie. This will repeat as long as the infection lasts; removing it surgically, cutting the head off, or gibbing the corpse will prevent resurrection.

Romerol is infectious, and anyone hit by a zombie while unprotected will also acquire a Romerol Tumor.
