so how do we add a new xeno-type to the world?

[Chilli Dog Dave]

there were talks about this in the previews but i have yet found a way to spread it outside of giving my custom germ to prisoners, is there not a way to make it more natural?
otherwise if not is there a way to add a custom one to the world as an option like dirtmoles are?
i wanted to add in some hyper aggressive tribal orkz but there doesnt seem to be any way to do this without a mod

you have to make your own mod for this example make a copy of Steam\steamapps\common\RimWorld\Data\Biotech\Defs\GeneDefs\XenotypeDefs.xml now make folders so it looks like Defs\GeneDefs\XenotypeDefs.xml go into game prepare to start a new game until you have the character choose menue and make a xenotype there 8icon for racetype xenotype editor)and save it this should apear in AppData\LocalLow\Ludeon Studios\RimWorld by Ludeon Studios\Xenotypes\racename.xtp open that file with wordpad should look likes this as example of the catrace i made
<xenotype>
<name>Catyan</name>
<inheritable>True</inheritable>
<genes>
<li>NakedSpeed</li>
<li>KindInstinct</li>
<li>Libido_High</li>
<li>Fertile</li>
<li>Beauty_Pretty</li>
<li>Hair_LongOnly</li>
<li>Ears_Cat</li>
<li>Headbone_Human</li>
<li>Voice_Human</li>
<li>Body_Thin</li>
<li>Hair_InkBlack</li>
<li>Skin_LightGray</li>
<li>DarkVision</li>
<li>Tail_Smooth</li>
<li>AptitudeTerrible_Animals</li>
</genes>
<iconDef>Crescent</iconDef>
</xenotype>
so you could copy this gene info over an existing xenotype in XenotypeDefs.xml but you should not rename the xenotype in your case neandertals would make sense giving them green skin gene ect (dunno if it exist)

example ork.xtp

<xenotype>
<name>Ork</name>
<genes>
<li>Immunity_Strong</li>
<li>Aggression_HyperAggressive</li>
<li>MeleeDamage_Strong</li>
<li>KillThirst</li>
<li>Robust</li>
<li>Beauty_VeryUgly</li>
<li>Ears_Pig</li>
<li>Jaw_Heavy</li>
<li>Brow_Heavy</li>
<li>VoiceRoar</li>
<li>Hair_InkBlack</li>
<li>Skin_Green</li>
<li>StrongStomach</li>
<li>RobustDigestion</li>
<li>Nearsighted</li>
<li>Nose_Pig</li>
<li>Unstoppable</li>
<li>AptitudeStrong_Melee</li>
</genes>
<iconDef>Basic</iconDef>
</xenotype>

The folders starting from defs can be put in any mod you use and it will apear ingame as a xenorace override ( its a quick and dirty edit you could make an extra mod from it if you read more how to do it).
