Gene extractor

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 genepacks from humans.


Gene extractors can be constructed once the Xenogenetics research project has been completed. They require Steel 200 Steel, Component 8 Component, 9,000 ticks (2.5 mins) of work, and a Construction skill of 4.


The purpose of the gene extractor is to collect genes from humans to be stored into a genepack. It is mainly used for collecting xenogenes from exotic xenotypes, but can also be used to extract the hair colors of baseline humans.

The extractor consumes 50W of power when idle, and 200W when active. It takes 12 hours for gene extraction to complete, during which time the occupant will be "suspended" and will not have their needs decay.

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. Interestingly, the job is considered "hauling" instead of "wardening". Quest lodgers cannot have their genes extracted.

Once the extraction is complete, the occupant will be ejected, and a new genepack with 1 to 4 collected xenogenes will be dropped nearby. The occupant will suffer from a condition called "gene shock" for 4 days, causing pain and lowering their consciousness and blood filtration. They will also need 12-20 days to replenish their genetic material, which does not have any direct effects, but will cause instant death if the pawn has their genes extracted before it wears off. If the extraction is interrupted prematurely, no effects will be applied.

Prisoners who have their genes extracted will have a -8 mood penalty for 25 days, titled "genes harvested". Colonist moods are not affected by anyone's genes being harvested, including their own.


Although it is possible, extracting baseliners is not recommended. They will only produce hair color xenogenes, which are only beneficial if you want to change a pawn's hair color and do not have access to the styling stationContent added by the Ideology DLC.
