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...
-Sometimes, areas are a little too dark.

Conclusion:

A fantastic campaign! It feels like Valve actually developed it! Kudos to you Acermors! :3

Pros:

+It had a great storyline; intro cut scene, survivor dialogue here and there made it more interactive...
++Unique event on the first map. I LOVED how you combined two events in one. :D
++Custom melee weapons.
++Custom voices in the event in map one (two?).
+AI nav is beyond perfect.
+Ending cut scene was AMAZING.

Cons:

-The finale has plenty of spots to camp, but it is kind of crowded when the tank comes.

Conclusion:

You should play this map, seriously. It was already good before 3.0, but it was made even better when it was added. :) 

Pros:

-The finale was AMAZING. Extremely creative on your part.
-Actually Felt like I was in China with the custom music, text, and other things.
-Challenging.
-Not a linear layout on the second map.
-Liked the firework event idea. 
-The Plane level really told a story on how the survivors got stranded in China.

Cons:

-Couldn't find ammo on the finale. If there was ammo then that was just me.
-Finale was kind of hard.... At first we started throwing fireworks down onto the ice, not knowing they would slide right into the water. So we ended up with no fireworks left, and still 1 spot of ice to melt. So you should definitely make some fireworks respawn if there aren't any left while the rescue boat is still stuck. 
-Spent 20 minutes on the Airplane level.... Couldn't fine the last parachute located near where you start.
-No throwables on the finale map can be a challenge.

Conclusion:

Overall, very good campaign. You should definitely download this.
