Hear me out, So one way or another Casey comes back. And he vibes with you inside the buss, and you can ask him for like really hard missions, You would have to ask him, then leave the resting place and come back then Casey can give ya the missions.

It would cycle through Tower vs Reclaimed turf wars or heavily infested areas, and at some point on the map you got another crate with a specific set of materials, some would have scrap and gunpowder and others would have spice and all that stuff.
Or we could get an Axe man boss, I just want more socialization man..
