Genetics is a game mechanic related to collecting, researching, refining and combining genetic material for use in splicing into characters to augment their abilities.

Unidentified Genetic Material

Main article: Unidentified Genetic Material


Unidentified Genetic Material (also commonly called UGM) is the main resource required for the creation of all genetic materials. UGM is looted from containers or creatures, or is purchased. To extract useful genetics from it, UGM must be researched. Researching requires one sample of UGM and one Stabilozine to be placed inside a Research Station. The outputted genetic material will be of a random type, with a quality between 10% - 60%.

Genetic Material

Genetic Material is the output of researched UGM. There are 12 different types, and each item has a certain "quality" or "strength" (both terms can be used interchangeably; they both refer to the percentage of the genetic material). The type of genetic material determines the buff received from the item when splicing, and the quality determines the potency of the buff (quality of the gene correlates exactly with the strength of the applied affliction when spliced). Note that quality does not increase potency linearly for all gene types - some genetic buffs are increased for each 20% increment in quality (i.e. as quality increases, the effect increases in steps). For example: The effect of Mudraptor Genes increases linearly with its quality, but on the other hand 85% and 100% Hammerhead Matriarch Genes provide the exact same buff when spliced. See each genetic material page for exact numbers.


The different types of buffs are as follows:

Gene Type Effect Quality Scaling
Crawler Increases swimming speed by [10-50]% Linear
Mudraptor Causes the subject to grow a mudraptor-like beak. The beak decreases damage taken to the head by [20-60]% and increases the beak's damage by [20-60]% Linear
Spineling Causes the subject to grow spineling-like bony protrusions out of their back, which can be shot out with the [Creature Attack] key. Gene quality increases damage dealt with spikes by [0-100]%. Linear
Hammerhead Allows the subject to to do [20-100]% more damage with melee weapons Linear
Mantis Increases movement speed on land by [10-25]% Linear
Moloch Increases resistance to physical damage by [10-25]% Linear
Tiger Thresher Decreases the subject's oxygen consumption by [20-100]% Linear
Hammerhead Matriarch Makes the subject's physical injuries heal at a rate of [6-45]% per minute Step
Hunter Receiving physical damage makes the subject gain a [75-150]% boost to melee weapon damage Step
Mollusc Receiving physical damage makes the subject gain [10-60] seconds of Vigor Step
Skitter Receiving physical damage makes the subject gain [10-60] seconds of Hyperactivity Step
Husk Slows down the progression of Husk Infections by 30%. When the parasite is about to take control of the host, the progression is slowed by [50-90]% instead. Highest quality genes block transformation entirely. Step


Refining

Refining is the process of taking two genetic materials of the same type, and producing a single genetic material with a higher quality. The quality of the product depends on the quality of both genes - the product will be higher quality input + 0.275 * lower quality input% + 3, or higher quality input + 0.275 * lower quality input% + 3 + 10 with the Gene Splicer talent. (The quality increase follows the formula and is capped at 25% resulting in 0% and 80% quality providing 3% and 25% increase respectively, then a +10% is added if the character refining has the Gene Splicer talent).

When refining combined genes you use combined genetic material and normal genetic material that is one of the two types in the combined genes, the process outputs a combined gene with the resulting quality of higher quality input + (0.275 * lower quality input% + 3)/2 or higher quality input + (0.275 * lower quality input% + 3)/2 + 10 with the Gene Splicer talent. Due to this you can turn low quality combined genes into maximum quality, provided the normal gene is of high enough level. For example, refining a 1% quality Hammerhead and Hunter combined genetic material with 90% quality Hunter genetic material yields 100% quality Hammerhead and Hunter combined genetic material as long as the user has Gene Splicer.

Since Gene Splicer adds a flat +10% to the resulting gene quality no matter the qualities, the increase per refine goes up from [3-25]% to [13-35]% ([1.5-12.5]% to [11.5-22.5]% with combined genes) , which is a rather significant increase, especially with low quality or combined genes, so it is advised to not refine genetic material until this talent is picked up.

Refining allows for the creation of high quality genes, but also has some risk. When refining, there is a chance that the product will be tainted. This taint chance increases with the higher quality input gene, and reduces with the medical skill of the character doing the refining.

The formula for the taint chance is: 0.99 * [highest input gene quality] * [1 - 0.00375 * ([Medical Skill] + 70)]

For any gene strength, the required Medical Skill to have a 0% taint chance is 197. This is unobtainable for Medical Doctors, who can only ever get to 180, but Assistants who apprenticeship medic can reach up to 200 with skill-boosting effects. It is possible to get to 230 if an assistant graduates the Medic tree, however such a high medical skill is unnecessary for the purposes of gene refining, and if the assistant does not graduate the Xenologist tree, then they are missing the very important Gene Splicing talent.

The taint chance is shown when placing genetic two materials of the same type in the Research Station, so there is no need for the player to do this calculation.

The Genetic Genius talent does not decrease the taint chance when refining. It only reduces taint chance when combining.

Refining maximum quality genetic material with another one of its kind produces untainted 100% quality genetic material no matter what, which provides the player with the ability to untaint genetic material.

Tainted Genes

Genetic debuffs are applied when tainted genes are spliced into a character. Tainted genes still provide the genetic buff and give a single random debuff that persists on the material until removed. Genetic material that has been tainted will be named "Tainted Genetic Material ([type])". Similar to genetic buffs, the quality of the tainted gene correlates to the strength of the debuff affliction. All genetic debuffs scale linearly with quality, with the exception of Outside Influence.

Effect Name Description Effect
Decrepify Subject's endurance is decreased. Reduces Vitality by [10-15]%
Glass Jaw Subject suffers from longer periods of unconsciousness when knocked out. [25-30]% less Stun resistance
Hypersensitivity Subject's skin is sore and more sensitive to touch. [10-15]% less damage resistance
Inflamed Lung Subject has an adverse reaction to oxygen. [0-20] Vitality reduction; increases over time.
Can be reduced with Oxygen Low > 10
Muscular Dystrophy Subject suffers from decreased muscle mass. Do [30-40]% less melee damage
Outside Influence Subject hears unintelligible voices inside their head. +[0.08-0.14] Psychosis per second
Rigid Joints Subject's joints are stiff and moving is more difficult. Move [10-20]% slower
Tunnel Vision Subject's eyes are sensitive to light. Blurs and distorts the screen
Xenobiology Subject's organs are resistant to traditional medicine. Affected by medicine [20-25]% less

Combining

Combining is the process of taking two different genetic materials, and producing a single genetic material that has the effects of both. Combining allows for double the genetic buffs to be applied when splicing, but also has a base taint chance of 100%. Medical skill does not reduce combining taint chance, so the only ways to combine genetic materials without tainting them are to either take the Genetic Genius talent, which reduces taint chance to 1%, or combining at least one 100% genetic material. Combined genes can be refined.

Combined genetic material will have quality of the average quality between the two input genes or the average + 10% with the Gene Splicer talent (contrary to the description of the talent, it also applies when combining).

Since with the Gene Splicer talent the resultant quality from combining can be higher than the quality of the genes that were used, it is not necessary to use 100% genes to create a combined gene with 100% quality; with the Gene Splicer talent, an average quality of 90% will be sufficient to create a combined gene with maximum quality.

This quality will become the strength of both genetic buffs upon splicing, even if they were not the same strength before combining. For example, combining a 20% crawler gene with an 80% hammerhead gene could result in a combined gene with quality of 50%, and such a gene, upon being spliced, would grant the effects of both a 50% crawler gene, and a 50% hammerhead gene.

Combined genetic materials will use the sprite of the genetic material that was in the left slot of the Research Station when creating it, but this is purely visual; the order of placement of genes in the research station does not affect the output.

Splicing

Placing genetic material in a Gene Splicer or Advanced Gene Splicer allows it to be spliced, applying its buffs (and debuffs in the case of tainted genes) to a character. To splice genes, place the gene splicer in the health interface slot (accessible from the Health GUI, default H). Once spliced, these buffs will remain indefinitely until the genetic material item is removed from the splicer, the splicer is removed from the health interface slot, or the spliced character perishes. Dying with genetic material equipped will taint the gene, though the splicer will always remain intact. It is not possible to interact with other characters' health interface slot, unless they are unconscious, dead, or an NPC crew member.

When using an advanced splicer, having the same type of gene in both slots will sum their qualities together, however not past 100%. Using two 40% quality genes of the same type inside an advanced splicer will result in a genetic buff with 80 affliction strength, but two 60% genes will only result in a buff of 100 affliction strength. In general, it is usually more effective to refine same-type genes than to try to use multiple in the same splicer.
