Fungus

[Halinder]

If you've ever paid attention to grass or flames in Rimworld, you may notice they occasionally let off small 'spores', which float around trying to find adequate soil or flammable objects. What if we had this kind of stuff for fungus? If the spores reach a dark area then they'll begin to grow there, forming a massive blob that can suffocate mountain colonies if not taken care of. It could be a nice surprise for one of the locked away rooms, too.

Fungus, or aggressive vegetation that need to be weeded (with flamethrowers preferably), are a cool addition.

[Cyclops]

Flamethrowers too, are a cool addition.

An underground fungus eating at machinery and power cables? That would make a nice incentive for not "Dwarwing"

[Klitri]

This would mess up so many mountain colonies, but I like that, it adds some form of balance to the game. The fungus idea is a great idea, perhaps it could poison colonists that are close to it if they're just standing around it inhaling the spores.

+1 on this idea I would like to see it also taint the food or eats the power cables like "Wex" said

[putsam]

+1 this idea it'll help bring colonies into the open again

[Halinder]

Just saying Tynan. Making mountain colonies less easy like you were talking about. Juuust saying

[MajorFordson]

Oooooh I'd LOVE to see underground plants.

Also as others have said, aggressive plants that can start to grow into your flooring or buildings if not controlled.

As well as physically active predatory plants, making the jungle even scarier! Or maybe desert sand trap type plants, like the Sarlaac in star wars!

[kingtyris]

This... is a good idea.

[Halinder]

Bump for the sake of actually really wanting Tynan to see this.

One of the best ideas I have read on this forum so far. +10000 for this to happen.

1. add new plant def
2. Mess with what ground it can grow on
3. mess with the seedshoot values
4. stick new plant in a biomedef

done. simples.

Also my MoreWeapons and MoreTurrets mods have a flamethrower.

After reading this, I thought about something like creep from starcraft, give the plant a fast seeding rate and make the "spores" invisible. The plant taking up the entire cell

[Wex]

To not make it unbalanced though, it should be limited to places with no sunlight (Fungi don't grow in sunlight) and have sunlight destroy it. Also, It would be fun, if left unattended, it clogs up rooms and corridors, to the point mining is necessary.
