"We are born different."
If you encounter tag flickering issues related to the Vanilla Combat Reloaded mod, head into MOD settings and disable the dodge mechanic of the Unblemished Blade gene. For other dodge mechanism-related problems, try the same solution.
Though titled Ratkin Gene Expansion, this mod can run independently without the base Ratkin mod installed.
When the base Ratkin mod is disabled, this mod revises the growth pod duration and nearsightedness effects, adds 31 brand-new genes, alongside 1 cultural meme (Cultural DLC required).
When the base Ratkin mod is enabled, all above changes apply, with additional content added as follows:
- 5 Ratkin appearance genes
- 10 new Ratkin subspecies
- 2 exclusive Ratkin gene-focused buildings
- 5 unique gene buildings for the Oberonia Aurea Empire (Oberonia Aurea Ratkin Mod)
- 5 Ratkin-themed quests and events
- 3 brand-new Ratkin factions
- 2 unique Ratkin starting scenarios
Beyond content additions, core Ratkin stats have been rebalanced to fit the expanded gene system:
- Toxic environment resistance: 90% -> 50%
- Aim time multiplier: 118% -> 105%
- Psychic sensitivity: 80% -> 100%
- Fixed the bug causing Ratkin children to mature far too quickly. (Relevant code referenced from https://steamcommunity.com/sharedfiles/filedetails/?id=2943840411&searchtext=Ratkin+Life)
[h2>Ratkin Subspecies & Faction Introduction[/h2]
Subspecies:
- Prime Ratkin: The original, purest and most numerous Ratkin subspecies, boundless in potential.
- Albino Ratkin: Mostly evolved from ruling-class bloodlines, gifted with exceptional social aptitude and bonus psychic sensitivity when holding authority.
- Lemming Ratkin: Free-spirited wanderers and carefree optimists; their wilderness survival skills are utterly reliable.
- Stone Ratkin: Unyielding and tough as bedrock. Their stalwart protection brings peace of mind, yet they are infamous for their fiery tempers.
- Snow Ratkin: Apex hunters of the frozen northern wastes. Their swift movements let them stand toe-to-toe with Neanderthals, though they bear a fatal weakness. Keep them far away from scorching work environments.
- Lowland Ratkin: Gentle Ratkin of coastal lowlands, possessing unparalleled craftsmanship across all realms. They make perfect artisans.
Factions:
- Lemming Federation: A loose coalition of neutral Ratkin settlements with weak internal restrictions. They favor peaceful trade over conquest, and their caravans sell nearly everything.
- Stone Rat Kingdom: A dominant realm ruled primarily by Stone Ratkin. Firm and uncompromising toward foes, yet surprisingly amicable to allies. Their smithing caravans trade all common raw minerals.
- Snow Rat Kingdom: An isolationist northern dominion ruled by Snow Ratkin, the most exclusive of the three Ratkin kingdoms—their strength more than justifies their cold demeanor. Their hunters trade exotic pelts from all manner of beasts, including Thrumbo hides.
- Stop spawning Snow Ratkin in deserts aaaaaa!

Q&A:
Q: Is this mod compatible with existing saves?
A: It should work fine in most cases, though a new playthrough is still recommended. If added to an ongoing save, you will need to manually add the rat ear gene.
Q: Compatible with CE?
A: Yes, fully compatible.
Q: Why are new factions not spawning properly?
A: If you have the base Oberonia Aurea mod enabled, ensure it is updated to the latest version.
Q: What about exclusive subspecies settings?
A: EVP subspecies will not appear within the new subspecies roster.
Q: Is this mod overpowered?
A: I can confidently state all content is balanced within vanilla power limits. Fully optimized gene-augmented pawns may sit slightly above vanilla’s power ceiling.
Q: Why are ratkin-featured humans spawning?
A: This stems from RimWorld’s native xenotype mechanics. Hard-blocking conflicting xenotypes entirely causes critical stacking gene glitches, so full elimination is impossible—only ongoing refinements can ease the issue.
Q: Why are ratkin aliens appearing?
A: Same root cause as above. This issue remains unpolished as new content development is still ongoing; major overhauls for this bug will come once content updates conclude.
Q: Why do Ratkin Test Subjects lose their ears when edited via CE?
A: Ratkin Test Subjects use dual gene layers: xenotype + lineage. CE can only modify one gene layer at a time and overwrites lineage data by default, erasing rat ear and tail lineage genes. The fix is simple: re-add these two genes manually.
Compatibility Notes:
I rarely use other gene-focused mods in my own playthroughs. Conflicts may occur with third-party mods that alter xenotype systems without dedicated compatibility patches.
This mod is fully compatible with Ratkin Warlords and Oberonia Aurea, and incompatible with Squeak Ratkin Expansion.
