Genes

This page is a list of genes. For a full explanation of the gene system see: Genetics

Genes are a system for adding capabilities to human pawns. They can be obtained from character creation or implanted via xenogerm.

Metabolic efficiency, denoted by the symbol, controls the rate at which pawns get hungry. Harmful genes will increase their metabolic efficiency, getting hungry slower, and thus consuming less food overall. Meanwhile helpful genes reduce metabolic efficiency, getting hungry faster, and thus consuming more food. A baseline human has a metabolic efficiency of 0 (100% hunger rate), and genes can bring it as low as -5 (225% hunger rate) or up to 5 (50% hunger rate). The game prevents you from giving pawns less than -5 metabolic efficiency; it doesn't stop you from exceeding 5, but hunger rate will not go below 50%.

Note that genes with over 5 cannot be extracted by themselves, and must be extracted in a pack with another gene that lowers metabolism cost.

Complexity, denoted by the symbol, affects how many gene processors you need to create a xenogerm from a set of genes. A gene assembler can create xenogerms with a maximum complexity of 6, plus 2 for every attached gene processor. Complexity also determines the base time it takes to create the xenogerm, ranging from 4 hours at ≤3 complexity, to 23 hours at ≥20 complexity (which is then scaled by the research speed of whoever operates the gene assembler).^{[Detail needed]}

Name	Description					Exclude
Scarless	Carriers of this gene have a special type of regenerator cell which can heal old wounds and chronic illnesses like bad back. Heals 1 scar, permanent injury, or chronic condition (Alzheimer's, Asthma, Cataracts, Carcinoma, Dementia, Frail, Hearing Loss and Blindness) every 15-30 days, akin to (and alongside) luciferium.	0	4	1		-
Gene implanter	Carriers of this gene can implant a copy of their xenogerm into another person through a somewhat gross-looking injector organ. Their own genetic material will then regrow very slowly. If they implant while their genes are regrowing, they will die. Adds ability: Implant Genes Implant this person's xenogenes into a willing subject using a special injector organ. If this person's genes are currently regrowing, they will implant their xenogerm and die in the process. When implanted, a xenogerm will overwrite the target's xenogenes. Germline genes will be unaffected. Passes on a copy of all xenogenes to a target. Causes genes to regrow for 2 years afterwards. Using this ability while genes are regrowing kills the pawn. If using this ability is lethal, then the caster will lose all of their xenogenes upon death.	0	3	1		-
Perfect immunity	Carriers of this gene have archite-enhanced immune systems which intelligently destroy invaders. They are totally immune to most normal illnesses. Immune to Flu, Malaria, Sleeping sickness, Plague, Infection, and Lung rot. These are all the diseases that are fatal and that adult colonists can acquire. Does not affect pre-existing conditions. Only prevents new illnesses.	0	3	1		Immunity
Non-senescent	Carriers of this gene do not go through senescence in the normal way. They never get chronic age-related diseases like cancer, bad back, cataracts, or dementia. Total immunity to carcinoma, heart attack, and chronic conditions (Alzheimer's, Asthma, Artery blockage, Cataracts, Dementia, Frail, but not Hearing Loss). Prevents these conditions from any source, not just aging. (e.g. nuclear stomach, toxic buildup) Does not affect pre-existing conditions.	0	3	1		-
Ageless	Carriers of this gene have archites in the bloodstream which continuously reverse the process of aging. Starting at the age of 13, carriers begin to biologically age slower. By 18, the aging process stops completely. Aging ×1 at age 13. Rate linearly slows as the pawn gets older. Aging ×0 at age 18.5.	0	3	1		-
Deathless	Carriers of this gene have archites in the blood which will sustain their life processes no matter what. As long as the brain remains intact, a carrier of this gene will never die. If a pawn would've died, but the brain, head, or neck is not directly destroyed, they enter into a regenerative coma. This coma lasts until otherwise fatal conditions are removed, then 7 days after that. Does not regenerate limbs or organs, except for the torso. Pawns with the Deathrest gene too instead enter deathrest, and lose all Hemogen. After lethality is removed, the usual deathrest mechanics take place. Entering the regeneration coma / involuntary deathrest will cause the pawn to lose 3% to 6% of total skill XP in a random skill.

Coagulate	Carriers of this gene have special glands on their hands and wrists, as well as a unique salivary compound that they can use to rapidly tend wounds. Adds ability: Coagulate Use special glands in the wrists to quickly tend someone's wounds. Tends wounds. [Detail] Target: Single target in LoS Range: 3.9 tiles Warmup Time: 60 ticks (1 sec) Hemogen Cost: 20 AI Can Use: ?	−1	1	Hemogenic
Bloodfeeder	Carriers of this gene have small retractable fangs and an organ on the roof of the mouth which can extract hemogen from fresh warm blood. They can bite an unresisting person, suck the blood, and gain hemogen directly. Adds ability: Bloodfeed Bite the target and extract hemogen directly from their blood. The target will lose blood and will be horrified by the interaction, but will be otherwise unharmed. A fast-acting coagulant will seal the wound to prevent bleeding. Can only target non-hemogenic humans. Hemogen gain is affected by the target’s body size. Feed on a pawn to gain up to +20 Hemogen, which scales with target body size, but not the user's. Target will gain +45% blood loss and the −5 Fed on moodlet (5 days, doesn't stack, negated by masochist trait and Bloodfeeders precept.). Also gains a bloodfeeder mark on the neck (+1% pain). If the target does not have enough blood, hemogen gain will be reduced accordingly.[Detail] Bloodfeeder must have a non-0% Eating capacity. Target: Single non-Hemogenic[Verify] human target. Must be downed or a colonist, slave, or prisoner not on a mental break. A warning will be given if it would kill the target or render them unconscious, but it will not account for continuing blood loss. +2 mood when near a blood torch. Interaction with Bloodfeeders precept. Bloodfeeders: Revered - Believers have a higher opinion towards bloodfeeders, negates moodlet for being fed on, mood bonus when bloodfeeders are in the colony or are the Leader, and mood penalty when they die. Bloodfeeders: Reviled. - Believers have a lower opinion towards bloodfeeders, mood penalty when bloodfeeders are in the colony or when they are bloodfeeder, and mood bonus when they die.	−1	1	Hemogenic
Longjump legs	Carriers have special hemogen-powered muscle fibers in their legs which allow them to jump great distances. Adds ability: Longjump Jump to a distant location using super-strong hemogen-powered legs. Jump to the selected location, over non-LoS blocking objects, quickly but not instantly. Immune to all damage during the jump. Target: Location in LoS Range: 19.9 tiles Warmup Time: 30 ticks (0.5 secs) Hemogen Cost: 5 AI Can Use: False	−2	1	Hemogenic
Piercing spine	Carriers grow an opening in their upper chest along with a quiver of keratin spines. Using a hemogen-powered chemical reaction, they can fire these spines at high speed at nearby targets with surprising accuracy. Adds ability: Piercing spine Use a hemogenic chemical reaction to launch a bony spine at the target. The spine exits through the skin from an opening between the collarbones. Given the method of launch, it is surprisingly easy to aim. Launches an unerring spine at the target, dealing 30 RangedStab damage, with an AP of 100% and a stopping power of 1. Target: Single target in LoS Range: 3.9 tiles Warmup Time: 30 ticks (0.5 secs) Cooldown Time: 60 ticks (1 sec) Hemogen Cost: 20 AI Can Use: True Market value of genepacks containing this gene: ×150%	−1	1	Hemogenic
Deathrest	Carriers of this gene must periodically regenerate themselves in a special coma called deathrest. Deathrest takes days, but can confer substantial bonuses. Deathrest can be accelerated and its effects enhanced by the use of a variety of special buildings and technologies. Those who put off deathresting will suffer from deathrest exhaustion. Creates a need for deathrest roughly every 30 days. Deathrest is initiated at a bed or deathrest casket and prevents action. It lasts for 4 days by default (3.6 days in casket), which can be interrupted for a stat penalty. If need hits 0, maximum Consciousness set to 50% and Psychic Sensitivity -100%. See the deathrest article for more details.	+6	1	Hemogenic

Superclotting	Carriers of this gene have extra-power coagulating factors in their blood, and will stop bleeding very quickly when wounded. Every 6 seconds, all bleeding wounds are automatically tended at 20-70% tend quality. The exact tend quality is fully random within this range. This renders it functionally impossible for the pawn to bleed out, at the minor downside of the wound being somewhat more susceptible to infection than being treated by a doctor under better conditions (e.g. by a skilled doctor, with industrial+ medicine, in a clean hospital). Does not affect non-bleeding wounds.	−1	1	-	-

Melanin

These natural skin colors are not available in the xenotype editor and cannot be extracted. Every person gets one of these as a germline gene unless they already have a skin-color germline gene (e.g. Dirtmoles have light gray skin instead of these).

These genes are defined in Core, not Biotech. They are all named "Skin color" in-game.

Name	Description				Removed	Reason
Resurrect	Carriers have a reserve of unique resurrector archites which can infuse a corpse, rebuild degenerated tissue and kickstart the vital processes. This brings the dead back to life - though possibly with health issues. This can only be done very rarely, and comes at a steep hemogen cost. Requires Hemogenic Adds ability: Resurrect Use archites in the bloodstream to infuse a corpse's body with new life, repairing degenerated cell structures and kickstarting vital functions. The older and worse-preserved the corpse is, the more likely it is that they will come back with memory loss or health conditions. This ability seems to exhaust the archites somehow, so it can only be used very rarely. Resurrects the targeted corpse, similarly to Resurrector mech serum Target: Any non-mechanoid corpse Warmup Time: 2 ticks (0.03 secs) Cooldown: 6,840,000 ticks (1.9 years) to 7,560,000 ticks (2.1 years) Charges: 1 AI Can Use: False Market value of genepacks containing this gene: ×150%	0	4	1	Before Biotech DLC release	Unknown.

Notes

• Certain genes will not be properly negated by other genes. For example, a drug dependency germline gene, while appearing to be negated by the same drug dependency as a xenogene, will instead cause the negative mood from the lack of the drug to start at 2.5 days instead of at 5 days.

Version history

• Biotech DLC Release - Added.
• 1.4.3524 - Children no longer get adult body types from genes.
• 1.4.3525 - Fix: Suppressed genes contributing to romance chance still apply.
• 1.4.3527 - Fix: Never sleep xenohumans still rest when caravanning alone.
• 1.4.3530 - Fix: Removing passion-adding genes doesn't revert effect.
• 1.4.3531 - Fix: AI sanguophages can use longjump without any remaining hemogen. Increase the effect of the temperature genes. From 3/?^[Value?]/10 to 5/10/20. Fix: Some hemogenic abilities can be queued without enough hemogen.
• 1.4.3534 - Fix: Melanin genes can be extracted by gene extractor.
• 1.4.3541 - Fix: Victims of bloodfeeder bites can gain hemogen from the interaction.
• 1.4.3542 - Fix: Coagulate can still be queued if hemogen is below casting cost.
• 1.4.3555 -
  • Psychic bond now gives +10% psychic sensitivity, or +5% if on different maps. Hediff description changed from This person has a psychic bond with another person based on the psychic bonding gene. to This person has a psychic bond with another person based on the psychic bonding gene. The bond itself grants some limited psychic awareness, allowing it to connect even with the psychically deaf. Bonds can now be created during lovin' allowing pawns already in a relationship when the gene was implanted to bond.
  • Many genes now give direct boosts instead of forcing traits, which allows genes and traits to stack:
    • Depressive gene renamed to Very unhappy, no longer forces Depressive trait instead decreases mood by −10. Pessimist gene renamed to Unhappy, no longer forces Pessimist trait instead decreases mood by −5. Optimist gene renamed to Happy, no longer forces Optimist trait instead increases mood by +5. Sanguine gene renamed to Very happy, no longer forces Sanguine trait instead increases mood by +10.
    • Slow runner no longer forces Slowpoke trait instead decreases move speed by −0.2 c/s. Fast runner no longer forces Fast walker trait instead increases move speed by +0.2 c/s. Very fast runner no longer forces Jogger trait instead increases move speed by +0.4 c/s.
    • Slow learner renamed to Slow study, no longer forces Slow learner trait instead multiplies Global Learning Factor ×50%. Fast learner renamed to Quick study, no longer forces Fast learner trait instead increases Global Learning Factor +50%.
    • Staggeringly ugly gene renamed to Very unattractive, no longer forces Staggeringly ugly trait instead decreases beauty by −2. Ugly gene renamed to Unattractive, no longer forces Ugly trait instead decreases beauty by −1. Pretty gene renamed to Attractive, no longer forces Pretty trait instead increase beauty by +1. Beautiful gene renamed to Very attractive, no longer forces Beautiful trait instead increase beauty by +2.
  • <Drug> addict-resist genes renamed to <Drug> resistant, Addiction-resistant genes for alcohol, smokeleaf and psychite provide a 50% reduction in tolerance buildup. Addiction-resistant genes for psychite, wake-up and go juice have a 50% multiplier on overdose chance. Smokeleaf and Alcohol resistant metabolism cost reduced from −2 to −1.
  • <Drug> addict-immune genes renamed to <Drug> impervious. Addiction-immune genes for psychite, wake-up and go juice grants immunity to overdoses from the drug. Addiction-immune genes for alcohol, smokeleaf and psychite provides a 100% reduction in tolerance buildup. Smokeleaf and Alcohol impervious metabolism cost reduced from −5 to −3.
  • Smokeleaf and Alcohol dependency metabolism gain reduced from +4 to +3.
  • Fix: Remove reference to damage over time in acid spray ability description. [...] stick to targets and burn them over time. to [...] stick to targets and burn them.
  • Furskin and beardless genes are now mutually exclusive.
  • Buffed furry tail minimum comfy temperature offset from −5 °C (−9 °F) to −10 °C (−18 °F).
  • When a deathless pawn takes damage that would have been lethal and falls into a deathrest coma instead, as an additional consequence they lose 3-6% of XP in a random skill. This should make non-death less trivial for these characters and preserve the sense of risk and danger. We’ll tuned this ongoing as needed.
  • Fix: Bloodfeed can be used on pawns in mental states.
• 1.4.3557 - Slow study gene applies a ×50% factor to Global Learning Factor instead of a −50% offset.
• 1.4.3563 - Fix: Pawns with "dead calm" gene can get into fights over botched conversion attempts. Fix: Genes that remove all passions don't save previous values, causing passions to reset on removal. Fix: Pawns being carried by other pawns strains psychic bond.
• 1.4.3613 - Fix: Reimplant ability not working with custom xenotypes.
• 1.4.3641 - Fix: Inactive sterile gene affects fertility.
• 1.4.3682 - Arresting dead calm pawns now never fails, to prevent them going berserk.
• 1.5.4062 -
  • Made psychic bond distance thought more permissive. As long as both pawns are on the same map and not suspended (cryptosleep casket) they get the positive thought.
  • Remove reference to damage over time in acid spray gene description. ("...it will stick to enemies and burn them over time." to "...it will stick to enemies and burn them.")
  • Added more acid filth texture options for acid spray so it never looks tiled.
  • Attached helpful text to mouse when selected pawn is aiming animal warcall ability.
  • Updated fire spew LOS highlighting.
  • Updated psychic bonding hediff tooltip to factor in pawns contained in buildings.
  • Clarify that pawns with no xenogenes cannot implant their xenogerm into another person. Show correct warning message on attempt.
  • Fix: Pawns with genetic drug needs aren't getting mothballed. Can improve performance in late-game saves.
  • Fix: Chemical genes affect tolerance buildup and addiction chance of all chemicals, not just the specified one.
  • Fix: On colonist selection, wasters and hussars are currently generating without their drug dependencies.
  • Fix: Small increments of pawn speed differences are lost due to integer calculations. Very quick and quick genes were effectively the same on an otherwise unmodified pawn.
  • Fix: Drug dependency endogenes aren't properly being overridden by other drug-related xenogenes of the same chemical.
  • Fix: Psychic bonds can form between two pawns that have the psychic bonding genes even if they are bonded to other people.
  • Fix: Pawns still carry a weapon after getting incapable of violence gene.
  • Fix: Pawns incapable of violence still can use combat gene abilities
