Pros:

Interesting concept
Very clean and polished design of the map
Falling cars in the pipes event :D
Pure randomness, yet so cool and awesome
Challenging but fun
Pouring  gas for item & others is new :D
Good NAV

Cons:

bots won't pick up med kits distributed throughout the map. they'll only pick up the ones in the saferoom.

Conclusion:

Honestly, you really made some different & new, but really fun and awesome campaign out of pure randomness like you said in the description. The gas tank being important for weapons & items is a cool concept. And that chamber in the second map with tanks in those... glass cases? God that really scared me. Thought they were all going to attack at once. The part where you have to go down the pipes while keeping an eye out for those falling cars is also fun. The bots follow the paths pretty well, but they wouldn't pick up med kits in the map. Other than that problem, it's real good, highly recommended if you're looking for a "different" game play.

Pros:

Everything
Custom Music
Absolutely No Bug
Gotta say that this is 20 times better than a valve map
Tank in a football jersey!
Variety of locations

Cons:

Well... the fact that this map isn't the official DLC.

Conclusion:

Just amazed by the work that's been put into this campaign. I'm so upset this isn't the official dlc. I see no bugs at all as if it were a valve map... no I'd not even compare this to a valve map cuz it's wayyy better than that.

Pros:

Beautifully Recreated
Custom Music
Brings back memories
Actual dungeon like the real game
Lost Woods
Funny Intro
Some Zelda enemies like Skullturas
Hearts that actually heal you.
PHANTOM LOUIS!!!!!!

____________________________________________
New in version 3

Thank goodness that 2.1 bug was fixed.
Rescue is coming music no longer interrupts the boss music.

Cons:

Bots still commit suicide.
Still some bugs that need to be fixed
Still only one of each Tier 2 weapon available.
-Bots usually take what I want before I try to get them.
Falling Ceiling room is impossible to get through.
"Make your way to the helicopter on the other side" message in the finale? But then I read that this is intended for the finale to work.

Conclusion:

I've got to say I'm really impressed with the hard work that has been put into this campaign. I do hope there are future updates/bug fixes, though. Also, the nav really needs more work as it's just impossible to play single player with the stupid bots. Also, I'd appreciate it if there were infinite number of weapons when placed in the map. I'd find a shotgun, and before I can take it, the bot takes it and there is only one of it that it's gone, and I'm stuck with Tier 1 in Forest Temple. What you did with the keys may be applicable to Rupees in the Kokiri Forest to be used at the shop. 

The rolling boulder is now easier, or it might just be me, to get through with bots following you. Now they rather stick very close to you as you navigate to the Kokiri Sword so they won't get killed by the boulder.

The falling ceiling room now works but is impossible to get through, especially with bots. We all basically die there and then have to start over from the saferoom. Maybe if you could, only for single player, make the bots wait until the actual player goes and presses the switch.

The ladder problem still remains... ARRRGGH!

 The idea of Middle Boss music as a replacement for the Tank music was absolutely awesome. That intro really cracked me up when Navi got eaten by a Hunter lol!

Overall, this campaign looks very promising and I'll look forward to the updates.

Pros:

Great map design
Good length for a campaign
L4D1 Survivors
No bug
Feel of New York
Lots of survivor dialogs
Well weapon placement
Ice Cream Truck lol
Both day & night
-->L4D1&L4D2 atmospheres at the same time
6-can scavange, but spread out so it takes time
Police cars run over a boomer lol

Cons:

none

Conclusion:

I waited to write a review until all the bug fixes came out so that I can give it a high rating. The level design is amazing, way better than Cold Stream, this should've been the next dlc. I won't complain about the missing police car dialog because that will be fixed when Dead Air comes out. Overall, the campaign itself is as if this were one of the official Valve campaigns. This is absolutely a must-have and one of my favorites.

Pros:

Great level design
Definitely could've been a DLC candidate over Cold Stream, I mean it's that good
Creepy L4D1 atmosphere
L4D1 Survivors
Plenty of Survivor Dialogs
Working Nav
The plane at the end was unexpected!
Virgil is also a Pilot lol!
The hidden DOMO-KUN!!!

Cons:

Absolutely none

Conclusion:

I can't believe they didn't choose this map to be the next DLC over Cold Stream. The level design is great, even better than some official campaigns. And yesss, I love the L4D1's creepy horror movie-like atmosphere. I also expected another boat rescue at the end as Virgil was the radio guy, but then turned out that Virgil was also a pilot!! This is the first campaign that I've actually given 100/100 review score. Great Job!

Pros:

No more boring map 1
The new mall map addition is awesome
Battery for defib
Coin?
Red propane
Custom music
Awesome intro!
New L4D there remix for the intro!!!

Cons:

That must be the slowest freakin forklift ever
Got rid of the green server button?
Lack of any sort of mall related dialogue from Dead Center?
It's always nick that says "Is anyone there?" @ the mall entrance.

Conclusion:

Best campaign I've ever played, but why is there absolutely no mall related survivor dialogue? I mean, dialogues from Dead Center can be used in this one! Even a simple line like "There's the mall!" can make things better. And the forklift event is ridiculous. The security gate is understandable but the forklift moving a millimeter per second makes this campaign unrealistic. And, why is there a 50 cal on the little ride? It's a ride for little kids. It's weird.

OK enough dissing, because this campaign is really good. I love the new intro music and so glad that the first map was deleted, so that now the campaign is more focused on the mall itself. I love the undead center map addition and the little elements like finding a new power for the defib, red propane tank for the wall busting event, and so on. I like this one better than the first release.
