Owning a primitive planet

[TheMack]

How do you own a primitive planet? The system is within my borders, but I cannot do anything to it other than build an observation post. I would really prefer to purge the alien lifeforms. How do I do this?

You need to build Assault Armys on your planets. Those come with transport ships. Then use them to invade the planet.

Just based on my main playthrough right now, if you click the observation post, you get a number of options of what you want to do with them. One option is to aggressively abduct them and I have no idea what the outcome would be but another option is to help them technologically. It takes away a bit of your science points and power credits every month but after a while the planet will turn into spacefarers and automatically turn into your vassal. After like... 3500+ days (I'm not sure how long exactly), you can use diplomacy to integrate them into your empire.

As for purging, no idea, maybe the aggressive approach will do that.

Either use the Observation Post to Infiltrate (if the natives are Industrial or higher) or build an Assault Army on one of your other core worlds and move it to the primitive and invade.

That will bring it into your empire, but then to purge them you need to have the policy that enabled it.

To kill them off before invading, I think an orbital bombardment for long enough might be able to kill all the native pops off eventually but I haven't figured out how to just move a fleet in and exterminatus yet.

It changes their ethos, usually to like xenophobes but there are other possibilities.

I usually just invade them if I want to take the planet. I don't see the point of dealing with uplifting them or whatever.

You get a diplomacy debuff if you purge so be ready to fight the guys around you.

You don't need to purge. They are only angry about being invaded for a relatively short period of time, and there's typically only ~3 pops there to begin with, any new ones that are born aren't angry.

Thanks for the replies. I went the assault ship route.

The game forces policies on you by the empire you create. Artificial morality. Some can do one step, other only the next. As a fanatic xenophile I can only observer or enlighten. Never invade primitive worlds. I get OP diplomatic bonuses, but dealing with these primitives (becoming vassals) breaking your boarders is a ♥♥♥♥♥. Some are great allies though.
