Immigrants Mod

Author of the Immigrants Mod: Zaljerem

Immigrants Mod brings inspired gameplay elements from Dwarf Fortress and the mod A Colonist A Day by WalkingProblem, creating dynamic immigrant waves that add variety and new colonists to your RimWorld experience.

Immigration Wave Mod Features

Default settings bring 1–5 immigrants to your colony every 15 days. Immigrants instantly join with no option to refuse, similar to the mechanics in Dwarf Fortress. Typical arrivals include colonists and tribespeople (who can arrive as children if Biotech is installed), but on rare occasions, ancient soldiers or pioneers with enhanced equipment may join. Here’s what you can expect based on other installed mods:

  • If Royalty is enabled, nobles may join occasionally.
  • If Simple Ogre Race is enabled, ogres may also join.

Arriving colonists and tribespeople (including ogres) can sometimes bring pets or livestock such as cats, chickens, cows, or muffalos.

Mod Settings

The mod includes extensive customizable settings:

  • Enable or disable the mod.
  • Set the minimum immigrants per wave (default 1, max 10).
  • Set the maximum immigrants per wave (default 5, max 25).
  • Set individual letter threshold (default 6; if more than 5 immigrants arrive, send one bulk letter instead of multiple letters).
  • Set the immigrant wave arrival interval (default 15 days, max 60 days).
  • Adjust the chance of an immigrant wave (default 100%).
  • Choose if immigrants should use the player’s primary ideology (Ideology only, default; otherwise random).
  • Allow children (with Biotech, default 10% chance).
  • Allow ancient soldiers to join (default).
  • Allow pioneers to join (default).
  • Allow nobles (with Royalty, default).
  • Allow ogres (with Simple Ogre Race (Continued), default).
  • Enable or disable specific animals: cats, cows, muffalos, chickens (default enabled).

Compatibility Notes

This mod is safe to add to an existing save. However, removing it from a save is not recommended.
