One of my favourite parts from grounded was the haze and the infected bugs. Their designs were amazing, and the idea of a fungal infection controlling them was so smart. I would really like to see some sort of infected bug make a return in grounded 2, whether it's an entire region/area, or just a small area on of the map that has been corroded by something. Or there could even be a new colossal/boss type enemy that could lure bugs in, infect them, then send them out into the yard to try and infect everyone else.
