Just a small suggestion for Multiplanet Raids, in case you ever feel like considering it.
It might be interesting to add an option that allows raids to occur even without the condition:
biters actually fighting you there (a biter was killed on the surface within the last 5 minutes)
The reason I thought of this is that I was playing with a multi-surface mod setup, where pollution-based attacks (the vanilla raids) were almost nonexistent. Even when my factories are idle, I think it would be fun to have occasional raids to keep a bit of tension and excitement.
On a different note, it might be worth adding the Enemies tag. It could make the mod easier to find for players who are looking for mods that make enemies more challenging.
