Pros:

-Detail is nice, author did his homework on China(did some googling of my own on some places and was surprised by the results)
-Difficult
-Interesting little features such as looting corpses, making Molotovs and finally, a Finale in stages
-AI soldiers fighting infected(and survivors)
-Animated paper lanterns

Cons:

-Odd beginning
-Panic event at end of second level was hard to navigate
-Long maps

Conclusion:

It is clear this took a ton of work, so props to the author on making all this in time for the contest, it is one thing to have a map like this and completely another to have it on the given time frame. The added little touches make this an amazing map to mess around in and the difficulty of the finale(objective I know) should make it enjoyable if your looking for a challenge.

Pros:

Dead Ends, because nothing makes it feel more realistic than getting lost
Custom Graffiti
Many great panic events

Cons:

None

Conclusion:

This is one of the quintessential Left 4 Dead maps.

Pros:

Highly detailed
Supplies placed well
Well designed, not a single cheap spot to hide

Cons:

Easy to gold
Only tanks and specials at the top, for the most part

Conclusion:

Great map, most fun I have ever had in survival. Only issue is that, as previous reviews say, at the top all you truly end up fighting is tanks and specials, as the common are dead well before.
