Use the RimWorld gene designer to plan a xenotype and check its metabolic budget — pick combat, immunity, psycast and personality genes — built for the current 1.6 / Odyssey version with the Biotech expansion.

Gene rules
- Xenogenes: installed in a gene assembler, cost metabolic, do NOT pass to offspring.
- Endogenes: inherited by children, cannot be freely changed once set.
- Metabolic budget: pawns need neutral or positive balance; negative genes can offset positive ones.
- Some genes (sanguophage) require special sources like archite capsules.
Community-consensus gene values for RimWorld 1.6 + Biotech. Exact effects and costs can vary by version.
Designing a Good Xenotype
Xenogenes cost metabolic points; negative-cost genes (weaknesses) pay for strong positives. A classic soldier xenotype pairs Tough + Fast Walker + Super Immunity offset by Nearsighted + Bloodlust or similar negatives. Endogenes are inherited — plan lineage carefully.
RimWorld Gene FAQ
What's the difference between xenogenes and endogenes?
Xenogenes are installed in a gene assembler and don't pass to children; endogenes are inherited and can't be freely changed.
Can I give a colonist too many good genes?
Yes — positive genes push the metabolic cost over budget. Offset with negative genes or archite capsules.
