First, logistics is now researchable in the second area, around the same time you're asked to research Active Defence and build a turret. So rejoice, you can get your undergrounds and splitters.
Second... logistics science is researchable at the same time. This seems like a bug, since it's the technology you have to research to complete the scenario. I did, of course, research it immediately to see what happened. I got no full attack waves. Just the occasional two-biter raids.
I spent some time researching other stuff before placing and loading my turret. Once I got to the production challenge, on completion, it just straight-up completed the scenario with no biter attacks at all. I had just over half my previous "minimum kill" run, in a much shorter timeframe. (This is the fastest I've ever successfully finished the campaign.)
I'm going to mess around a little more and see what else I can find. I originally started this run to check whether the game ever explains power (it doesn't), whether pollution is still displayed on the map and in tooltips (it is), and whether reducing production during the attacks will help lower the difficulty (I couldn't test this because I got no attacks).
But it is Mardi Gras, and I have got hurricanes to drink and jambalaya to eat, so I'm probably not going to make another cut at this for a while yet.
