Really cool, love the mod, but the enemies scale faster and are harder than any other surface enemies (nauvian, explosive biters on vulcanus, etc.). Plus, not a lot of room to defend on islands.

So overall it makes Fulgora the hardest planet to work on with the most awkward space... It would be really nice if I could tone down their strength somehow because right now there is no way to control them....

ok, thanks for the feedback. I'll add a mod option to tweak damages

Might want to tweak the the default the damages. A tank gets gunned down by a small (5-10) level 1 walkers immediately. It is also possible to be spawn camped by them. I would suggest a more aggressive safe zone around spawn.

Overall, great work. It is very difficult to add enemies to Factorio - I did try it myself and you can see the horrid results for yourself.
