Rimworld Create Xenotype

Creating a xenotype at the start is easy. Creating one during a playthrough is a scientific endeavor.

To create a xenotype in-game:

Warning: In-game created xenotypes replace the pawn's current germline genes. If you inject a Dirtmole with a Genie xenogerm, they become a Genie. However, their children will still inherit the original Dirtmole genes unless you change the parents' endogenes.

These change the pawn's body.

What it does:
When creating a custom xenotype, you can define how its genes are inherited and expressed in future offspring — not just in the initial pawn.

Key elements:

Once you have multiple xenotypes in a colony, interbreeding creates hybrids. The system selects genes from both parents, with each gene having a 50% chance to be inherited. If conflicting genes (e.g., Fire Breath vs. None), the dominant one (higher complexity or explicit dominance) wins. rimworld create xenotype

Strategic Implications:

Low Pain (works through injuries), Robust Digestion, Naked Speed, Very Unattractive, Violent Disabled (custom: cannot do violence). They haul, clean, and farm. Their rebellion story writes itself when a baseliner colonist befriends one.
