Mod «Biotech Cloning» for Rimworld (v1.4)

Biotech Cloning

Allows you to use Biotech's growth vats to grow clones asexually from only one donor parent regardless of fertility or age, copying their entire xenotype.

How to Use

  1. Research the new Cloning research project.
  2. Build a Clone Extractor (in the Biotech architect tab and costs 4 Advanced Components, among other things)
  3. Place a colonist into the Clone Extractor
  4. Place the resulting clone embryo into either a growth vat or implant into a living mother


Includes an optional mutations system where clones have a random chance to gain genes on birth. Settings allows you to customize overall mutation chance as well as which genes are eligible for mutation and how likely each gene is. Defaults are mostly negative mutations but any gene can be added to the list, including modded genes in theory.


Includes a new starting scenario based on the classic Rich Explorer from vanilla with a twist. You start with the tech and building materials necessary to begin cloning yourself right away. Make sure to pick a pawn with enough construction skill to actually build the machine, though.


  • Should be totally safe to add to existing saves
  • Not (currently) compatible with Humanoid Alien Races. Coming soon hopefully.
  • Should be compatible with Questionable Ethics Enhanced, even though they do the same thing in different ways.
  • No other known incompatibilities, please let me know if you find one.
  • CE? I have no idea, but sure. Why not, it should probably work. Try it out and you tell me.

Known issues

  • Humanoid Alien Races is simply not compatible. It does a lot of things to pawns like custom bodyTypes and such that I will have to add a lot of custom patches for, and I want to wait to do all of that until it at least officially supports Biotech. But I do plan to work on this in the future.

Requires Biotech DLC.
