I'm curious as to the stealth mechanic of Infested. I assumed it was a hive mind thing or that chargers barking alerted them, but recently I played an Infested mission where I attempted to stealth as much as I could. I was spotted, and had to fight the infested normally (no ancients that I ran into I believe until later). However, when I went in the next room I was able to continue stealth killing leapers, runners and chargers as if they were not alerted. This happened a few times. How does this happen?
