Thank you so much for your replies! Actually, while I was waiting for them, I tried and tested on my own, and realised that biters appear in an area that isn't scanned by radar, for example. The situation I've got now is this: I have a peninsula. The part that goes to the land I walled with defence,...

I had to google "factorio kusak" to figure out what you mean, it seems like it's how biters are called in Russian? Well in that case, new biter nests are created by living biters; existing nests will sometimes create small groups that go to a location and create a bunch of new nests there...

Hello everyone! Please tell me, is it possible to somehow privatise the undeveloped territory from the kusak? So that they do not appear, for example, in the illuminated territory. Or how does it work already in 2.0?

Thank you!
