Can you exterminate a faction?

[Ford_Prefect]

Can you go on a world tour and if you destroy every enemy base of a faction... eliminate them?

[Ser Kitteh]

Yes, it's completely doable. However all raids afterwards will only be mechanoids.

[Kirby23590]

Yup. But you might want to keep a hostile faction alive to keep those pesky mechanoids coming, unless you want alot of plasteel or components.

Here's an old quote from a different post many years ago.

What happens if you eradicate all their settlements? Do they stop raiding, or does the faction vanish? Nothing?

Testing in on the 5% world with one pirate base there with dev mode...

And throwing every mechanoids in there... And destroying their last base, yup eradicating them from the planet does make them not raid you at all, and further testing that the raids were replaced by the only hostile tribe and then making them friendly only to be replaced by a mechanoid hive instead... In the faction tab the pirate's name has (defeated) underneath their goodwill, meaning they will never show up! never!

But removing the pirates face's from the rimworld by destroying their last base makes them homeless and they probably didn't survive the wilderness, meaning they ran into a giant horde of manhunting yorkshires or they were too disorganized and only self-destructed by doing what pirates do best. But some smart surviving members ran into nearby outlander vilages taking in disguises as friendly wanderers joining in. Well now you know...

Yes you could do it if you want... But their bases would be far away which would take miles away in a normal world size or in a larger size which would take for days to get to one of their bases.
