Booted this up and gave it a go...lots of issues.
Some issues I saw :
Loot spawning above ground, sometimes unable to access
Mashed the keyboard until I found out the 'H' key was the one I needed to eat/drink.
Zombies and cars predictably spawn on roads (and fall from the sky as they do)
Many zombies spawned frozen in place.
Found a Fully loaded and fueled Pawnee at the main airport (lol wut).
I'm guessing you intended this to be a framework that other mission designers build upon and flesh out, as the mod by itself cannot hold someone's attention for longer than 30 minutes.
