Pandora Expansion - (Unofficial) Biomes

This is my personal and very much unofficial pandora biome. I made this in most part for my own playthroughs and will likely be adding stuff as I go when I get the chance.

Highly recommended mod to remove green haze from toxic fallout:

What it adds:

- Ashlands & Pandora Biomes with a persistent toxic fallout to keep it similar to the films.

- Some toxic resistant trees to keep the jungle vibes.


Updates:

04 June, 2026: added glowing willows and helix plant


Frequently Asked Questions:



CE Compatible?

Yes


Does this come with new species of animals?

As of this moment no, they're are insects that roam the area so it's not completely baren and I will likely be adding the occasional animal here and there when I get to it.


What is the point of this?

Mostly set dressing. Toxic fallout almost always wipes any animals and plants off the map so this is my way of having some AVATAR esque biomes that live in the toxic air.


Does this function with your other mods?

Yes, the NA'VI xenotypes are inherently toxic resistent.


Can I patch this or use it for my own stuff?

Absolutely, this is very much just a personal edit I use for myself that I'd thought others would enjoy.


That is a metric ton of trees?

Yep, which will hopefully change up some of your raiding strategies.


Enemy pawns don't spawn with gas masks / aren't ready for the constant toxic fallout?

Yep, this only changes biomes. To change factions I recommend Rimsential - Total control, but any faction editing mod should work


Why the Odessy requirement?

I patched some of the assets from Odessy to create this mod and I'm unsure how rimworld will react without it, but feel free to try.
