Pros:

+Dynamic pathing all throughout the campaign
+Creepy, horror atmosphere
+At the car alarm park on map 3, all of the alarms flashing had a mesmerizing affect.
+Explosions on the end map and map 3 look even better against the night skyline.
+AI nav is perfect.
+Limited amount of guns and supplies.
+Added car alarm on map 1.
+Actually had to use my flashlight.
+Added survivor dialogue.
+Graveyard looked AMAZING with the fog.

Cons:

-When dialogue lines are triggered, they can sometimes interrupt or overlap others lines...
