dark souls-esk multiplayer maybe?

[psigen]

Heard about that multiplayer might be a thing in the future...

Maybe do a similar thing to what the Souls games did, and have people be able to invade with a limited amount of colonists?
Inversely allow players to send out a distress signal and allow a 3rd party to intervene or drop some needed resources or even send a colonist or two as AI...

I understand this is complex... but it would be cool
