Updated again 3-12-23. I took out almost all of the original AI and put in my own groups. In testing, spawns seemed all out of view, and things should be somewhat on and off hard. Spawns when they happen are the same, but they are mostly 66 percent chance, some are 50 percent. So with some luck they aren't even there. If they are, it'll be something you can expect to be the same thing next time around. In testing I got about 173 kills to get to zulu, which include 3 panhards. I also went right down the middle, meeting more enemies you may meet on the edges of the sewer system.
