Genes

Genes are a system for adding capabilties to human pawns.

Metabolic efficiency, denoted by the symbol, controls how much food a human needs to eat. Harmful genes will improve their metabolism, so they don't need to eat as much, while helpful genes will worsen their metabolism, making them eat 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%.

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).

Name	Description
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.\n\nWhen 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.	0	3	1
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).	0	3	1
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
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 ×? at age 13 Aging ×0 at age 18	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 (or head/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[And?]. Pawns with the Deathrest gene too instead enter deathrest, and lose all Hemogen. After lethality is removed, the usual deathrest mechanics take place.	0	7	1
Archite metabolism	Carriers of this gene have special archites in their cells that facilitate and optimize metabolism. This improves overall genetic and metabolic quality. Increases metabolic efficiency. No other effect.	+6	6	2

Alcohol impervious	Carriers of this gene never get addicted to Alcohol. Alcohol addiction factor: x0% Alcohol tolerance build-up: -100%	−3	2
Smokeleaf impervious	Carriers of this gene never get addicted to Smokeleaf. Smokeleaf addiction factor: x0% Smokeleaf tolerance build-up: -100%	−3	2
Psychite impervious	Carriers of this gene never get addicted to Psychite. Psychite addiction factor: x0% Psychite tolerance build-up: -100% Overdose chance: ×50% [Only this drug?] [Random or All?]	−5	2
Go-juice impervious	Carriers of this gene never get addicted to Go-juice. Go-juice addiction factor: x0% Overdose chance: ×50% [Only this drug?] [Random or All?]	−5	2
Wake-up impervious	Carriers of this gene never get addicted to Wake-up. Wake-up addiction factor: x0% Overdose chance: ×50% [Only this drug?] [Random or All?]	−5	2
Drug dependency	Carriers of this gene need to ingest drug on a regular basis to survive. After 5 days without drug, carriers will suffer from drug deficiency. After 30 days, they will fall into a coma. After 60 days, they will die. ? Teetotalers will take the required drug without penalties, but ideoligion can still block taking them. After 5 days without the drug, pawn gets 70% max consciousness, 80% max moving, and 50% max manipulation, as well as -6 mood. Grants immunity to the chance of instant major overdose upon consuming the drug in question. It does not prevent cumulative overdose from consuming multiple doses/drugs. Specific drug addiction factor: x0% Children under 13 do not get any of the ill effects from not using these drugs. The timer for penalties only starts on their 13th birthday.	+4	1

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	0	4	1	Before Biotech DLC release	Unknown.
Skill apathy	The carrier will have no passion in (skill).	2	1	-	Before Biotech DLC release	From an XML comment: "Removed since the downsides are too easy and boring to avoid, and synergize with skill loss genes too much. If you already aren't using the skill it's too easy to just kill passion on it too. -Ty"
Drug addict-sensitive	Carriers of this gene get addicted to (drug) very easily. Specific drug addiction factor: x9999%	2	1	-	Before Biotech DLC Release	From an XML comment: "Removed since these just aren't very interesting, very narrow in application, and the downsides are too easy and boring to avoid. Just not much interaction or story here. -Ty"

Notes

• Genes that are restricted for specific xeno humans will cause a bug if its present at humans not belonging to said xeno races. (i.e: unable to draft)^[Clarify]

Version history

• Biotech DLC Release - Added.
• 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.
  • 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 "Very happy", no longer forces Optimist trait instead increases mood by +10. Sanguine gene renamed to "Happy", no longer forces Sanguine trait instead increases mood by +5.
  • 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.Slow runner no longer forces Jogger trait instead increases move speed by +0.4 c/s.
  • "<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.

• • Softened metabolism costs for smokeleaf and alcohol genes.
  • Furskin and beardless genes are mutually exclusive.
  • Learning genes offset global learning factor of a pawn instead of forcing traits.
  • Beauty-related genes offset pawn beauty directly instead of forcing traits.
