Pros:

-Difficult
-Lots of fun with friends who know how to aim

Cons:

-Ugly
-Repetitive
-Pushing any button gets you punished
-Finale is broken
-A map entirely based on grabbing fresh M60's to kill tanks with so many throwables and items that it's really just a boring marathon that's only difficult if you're rushing like a bum
-Confusingly structured

Conclusion:

The way this map is put together is possibly very neat. But everything else about it is downright bad. It's not that it's too difficult, it's that the difficulty is piled on so high that you need T2's and M60's to get passed it, then it becomes laborious rather than difficult, as all you can do is trudge through the map holding M1 and S every time a tank spawns. Throwables a plenty so there's no reason to be afraid of the horde, but again it just become monotonous and boring. And the finale is completely broken. You fight the two finale tanks before you can hit the finale button. Not sure how any of that is SUPPOSED to work, but when you do hit the button it says rescue is coming but the door to the train never opens making all the monotonous effort we went through to complete the game pointless, thus resulting in a 1/10

Pros:

-None

Cons:

-Monotonous textures
-Various parts with below subpar architecure.
-Skybox didn't work at all?
-Died on map 2, restarted at the saferoom at the end of map 2
-Numerous bugs
-Horrible map flow
-Confusing events

Conclusion:

This has got to be the worst map I've played by far. It's beyond unfinished. Every step in the map I found another flaw in the design. Map 1 has a great example of terrible architecture, you head down an escalator and make a left turn. The left turn in the first place is completely out of place as that's not really where someone would put an escalator but even more, the stair well down to the left is just a cheese wedge that barely blends into the escalator. All the walls were plain and boring. There was a gnome I couldn't pick up. Map 1 had a series of display cases that held numerous things that would never be put into a display case, I'd look the other way if they were all items you could carry, pills, medkits, etc, but various things were just physics props. Gas cans in a display case???? I also saw almost no reason to recognize this as a campaign based in China. I gave this a 1 because it was by definition a map, but that's it.

Pros:

-Very creative and unique approach
-Bosses
-T2's are almost a requirement, whereas most maps they just make them easy and boring. So the difficulty is a huge plus in my book
-Basketball

Cons:

-Bland design
-Couldn't finish the map?

Conclusion:

On an earlier playthrough with just 2 people we died (and hadn't found a certain secret) so we just had too much trouble. Recently we did it with three and discovered the secret so we made it through the map with some semblance of ease. Lots of horde and lots of tanks. The AK's just shred everything so that's not really the map makers fault no marks there. But after completing all of the puzzles we could not put all of the pieces onto the thing in the center. We searched extensively for 20+ minutes to make sure we hadn't missed anything else we simply could not place the fourth puzzle piece onto the monolith. Is this by design? If so please notate somewhere that it requires four players to complete! Otherwise I suppose we experienced an obscure bug that disallowed us to place the final piece so I'm not sure what to make of that, so I'm scoring this on what I did play of the map, and marking off slightly for the puzzle piece issue. If it is a requirement to have four players, and you explicitly state that in the description then I will revise my review. I do recommend this to anyone looking for a "different" way to play L4D2 with your friends, but I urge you to bring four people either way as the bots are incredulously worthless either way.

Pros:

-Multiple tanks per level seem to occur often.

Cons:

-Enough glitches that it's pointless to name them all here.
-Very dull environments.
-Loop mapping.
-Terrible map flow.
-Most of the paths we took to complete this map seemed to not be the intended path, often involving common hopping or jumping from rails to rooftops. NOT an ideal way to progress through a map intended for a mainstream casual co-op audience.

Conclusion:

I completely hated this map. The visuals had the "grimey" feel that I like, but were just plain boring. The glitches would make this map unplayable to a large amount of the casual community as far as I can tell. And the map flow was absolutely awful. In particular, the only way we could discover to get to the area of the finale to activate the chopper was to common hop. I enjoy multiple tank fights. I enjoy nearly constant horde. I enjoy difficult levels. But this was difficult for all the wrong reasons. I don't even see the potential here, besides an acknowledgement that it's okay to have multiple tanks per level and lots of hordes. I recommend a full rework mostly from scratch, scrapping all of the "looped maps" And as far as downloading this map goes? Don't. I'm only giving it a three because I was kept engaged by having to fight tanks and zombies nearly constantly which left me with very little time to complain about how badly the map was designed until we finished it.

Pros:

-Long Maps
-Varied scenery
-Pistol
-The finale

Cons:

-Missing textures requires more work than it's worth to install this map
-Horrible map flow
-Most events are just ripped straight from vanilla maps
-Little to no visual or audio clues as to where to go(see map flow)
-It's strange that only 2 of the T2's have been reskinned, and their skins do not match the environments that the map takes place in.

Conclusion:

I have no idea how this got rated so highly. It's cluttered. Wide open purposeless spaces. It's confusing, and L4D is not a game that is made for "exploratory" maps. I don't recommend this for download for anyone casually looking for a finely polished L4D2 campaign. If you download every map and try it then go for it. Otherwise hold out until this is properly packaged and hopefully receives some much needed attention in the flow department. It has a lot of potential honestly, it's just not reaching it. I do think the finale made for quite a fun experience though.
