Yes, it works on 1.5.60.

Does this work on 1.5.60?

No, making it harder to one-shot your enemies without taking casualties. You should see more "Minor victories", where both sides have taken losses without a clear winner. Prolonged fleet engagements will also deplete the fleet crew(manpower), making it harder for them to invade.

However, if you clearly out-tech or outnumber the enemy, it will still be a one-sided slaughter. Changing that would require something even more drastic like cutting out the entire tier 4 and 5 weapons. (Beyond the scope of this mod.)

I got tired of just Missile'ing entire fleets to death without a scratch. Consider this an "increased difficulty" style of mod. Though don't worry, everything I nerfed is still viable as a weapon pick. Plus, the manner in which I nerfed things gives secondary tactical considerations, if you know where to look.

I see a lot of nerfing here, are you trying to make space, safe?
