Pros:

Good Mapping
Custom vehicle skins
custom music
good distance between safe-houses
The Temple was cool
good ammo distribution 
good eye for detail

Cons:

At the beginning of the first map and at the finally the grass is rather bright.

the first level is a bit too clean for a zombie over run city-mess it up some
The first level needs more wandering zombies and some ground level zombie hordes.

Conclusion:

This is a well made and fun campaign to play. Did a fantastic job on the custom skins for the vehicles. Loved having the wall as the finally, it gave your campaign that actually escaping China feel.
