Pros:

fun
has a lot of weapon and throwable around
multiple route to go (could be a con for some people)
level of details

Cons:

might get lost or go around in a circle
some maps like the final battle has this *spoiler* huge military field and it is just you walking across this big empty place with little zombie and all you need to do is stay near this one building for battle

Conclusion:

on the final map, it would be better if you have to run to one side to activate the final battle then run back to the other side to catch a ride or something. otherwise, this map is average. it has some nice features here and there, but it does not deserve a 1 or 95.
