Sorry, as a new modder I didn't notice the discussion page. Talk about defense structures, I think their stats may not work well with vanilla Stellaris balance, so there is two options: create a standalone defense structures mod with modifierd stats to suit vanilla game, or create a compatibility patch for for the mod of your choice. What you say?

i think compatibility is going to be the most of work for you, but its your choice :p

Do you think where I should start? Perhaps ESC? Or NSC2?

im using SCX, but i think NSC is more popular :p

I made a SCX patch, but not tested yet. I'm going to test it tomorrow, but you can try it before that.

thank you!
