Gene extractor
An automated surgery machine that can extract a person's genes and create a genepack from them. The extracted genes will be randomly selected from the person's xenogenes and germline genes. You can force someone into the machine, but they won't like it.
Extracting a person's genes while their genes are currently regrowing will kill them. Otherwise, gene extraction causes no lasting harm.
Genes that require archite capsules are too complex to be extracted.

The Gene extractor is used to extract copies of genepacks from humans.
Acquisition
Gene extractors can be constructed once the Xenogenetics research project has been completed. They require 200 Steel, 8 Components, 9,000 ticks (2.5 mins) of work, and a Construction skill of 4.
Summary
The extractor consumes 50W of power when idle, and 200W when active. When active, a gene extractor will collect genes from humans to be stored into a genepack. Colonists can be ordered to enter the gene extractor either by right-clicking it with a colonist selected, or by using the on-screen gizmo. Prisoners can be loaded into the gene extractor using the on-screen gizmo. Once a prisoner has been selected, a colonist will haul them to the extractor. This job is considered "Hauling" instead of "Wardening". Quest lodgers cannot have their genes extracted.
In order for a pawn to enter the extractor, they must have one or more genes aside from their melanin (natural skin color) and hair color genes, meaning that baseline humans are exempt. The extractor can still extract an occupant's hair color or non-natural skin gene, if present.
It takes 12 hours for gene extraction to complete. The occupant is not suspended during extraction, and will still have their needs decay. This means that a pawn may be starving or exhausted by the time they leave. Once extraction is complete, the occupant will be ejected, and a new genepack with 1 to 4 collected xenogenes will be dropped nearby. If it is not powered for 24 hours, then extraction will be canceled.
Once extracted, the occupant will suffer from Gene Shock for 2 days, causing pain (+5%) and lowering their consciousness (−5%) and blood filtration (−15%). They also gain the Genes Regrowing condition for 12 to 20 days. This does not have any direct effects, but will cause instant death if the pawn has their genes extracted before it wears off. Prisoners who have their genes extracted will have a −8 Genes Extracted moodlet. Colonist moods are not affected by anyone's genes being harvested, including their own.
Gene selection
Attempted number of genes to extract is weighted as such:
- 1 gene -> 0.7 weight
- 2 genes -> 0.2 weight
- 3 genes -> 0.08 weight
- 4 genes -> 0.02 weight
After a number of genes to extract is selected, the following rules must be adhered to for selecting genes:
- Sum of all genes' metabolism score is required to be within -5 to 5 range.
- Archite genes cannot be extracted.
- Melanin skin color genes cannot be extracted.
- No duplicates.
If a gene has > 0 complexity, it has a selection weight of 3, otherwise its weight is 1.
Xenotype Extraction Table
The following table serves as a reference for which xenotypes to extract for specific genes. Bear in mind that many genes are not used by any xenotype, and must be acquired through trade or quests.
