Hello. It would be very cool to implement a pollution and evolution system. I beleive it is possible to do. Some event would need to increase "pollution" for example, processing scrap and using EM plants could increase "pollution" but it is called "EM radiation" in the GUI. Then set up a scale for the enemies using the evolution mechanic and tie the two together.

Provided you could attach the pollution to accumulators as well that might be interesting. It'd make the dense scrap patches a lot harder to secure, and might encourage some rather unique train setups if you want to go accumulator-less on those islands. Though I wonder how annoying/difficult it would be to defend.
