You can create a custom xenotype at the start of a new game or mid-save using genetic infrastructure. At Game Start: In the "Create characters" menu, select the Xenotype editor
The editor looks intimidating at first—a massive grid of colored hexagons. But it operates on a simple economy: and Metabolism . rimworld create xenotype

If you are already playing, you don't "create" a xenotype in a menu; you engineer it: , which is then implanted into a pawn
: Use a medical operation to implant that Xenogerm into a colonist. This overwrites their existing xenogenes (but not their germline genes) and officially changes their xenotype to whatever you named your custom creation. Key Terms for the Feature
You cannot go below -5 Metabolic Efficiency . If you want powerful combat genes, you must take "bad" genes (like nearsightedness or slow runner) to balance the hunger cost. 2. Complexity
