Pros:

+ Cool idea to take place in San Francisco, the plot, going over the bridge, etc.
+ Nice skybox - not sure if its a vanilla one I wasn't familiar with or custom. if custom then def the best part.
+ Some cool interiors like the house on the beach

Cons:

- Bad optimization. First thing me and my friends noticed. Map didn't run that well in comparison to the official maps.
- Very ugly environments and visual quality. None of the place was pleasing to look at all.
- Bad sense of direction
- Map felt really sluggish and slow overall
- Some hordes just way too long
- Just dragged on for waaay too long. This is an example of how a campaign can be too long.

Conclusion:

It picked up a little in the third level but overall this was just a very boring campaign for me and my friends that played it together. Its one I would never play again after the first time.

Sorry, just didn't think it was good.

Pros:

+ Nice looking outfit
+ Modified hair to be longer

Cons:

- Ugly skin
- Jittery hair when running directly backwards
- Messy model like around the shirt collar
- Very bad neck seam
- Distorted legs right above the knees on the front

Conclusion:

Overall its a nice outfit, but really needs work to look good.

Pros:

Awesomeawesomeawesome
Finally played through this campaign after quite a while and thought it was pretty great.

+ It looks like Minecraft :D
+ A lot of items are changed in appearance as well as the player skins. Without this, it would of been pretty blah.
+ Good presentation like the intro and the overall quality seen throughout.
+ Some neat events and having to find things to build Minecraft items was great
+ Good variety of areas
+ Awesome easter egg
+ A good length
+ Enjoyable escape
+ L4D1 Survivors

Cons:

- The gun skins didn't want to overwrite what I normally had.
- Zoey's skin wasn't too appealing. 
- Some of the areas didn't look that great when it comes to MC building

Conclusion:

Overall a really awesome campaign. Would get a 10/10 if the gun skins changed. The melee ones, pills, player skins, etc. all worked fine but the guns appeared ordinary to me.

Pros:

+ Very professional overall.
+ Fantastic loading screen.
+ Best campaign intro ever.
+ Great visuals (for l4d2 of course) The starting area was really neat (and spooky) and throughout the map there were some nice looking places - especially the finale.
+ A few real neat areas.
+ Entertaining. 
+ Great L4D atmosphere
+ Nice secret/ easter egg
+ Fun finale for the most part.
+ Seemingly fair weapon selection
+ Fine length.
+ Good amount of different events.
+ Overall a very impressive campaign that is so well done.

Cons:

- Poor optimization. A majority of the campaign played smooth for me but everyone I played with said they had lag issues and in some parts of the campaign even my framerate would suffer.
- Too damn hard. If I play an advanced mode campaign, it shouldn't give me as much trouble as expert mode does on the official maps. After several attempts on level 2 and a full team, we gave up. 
Later tried it by dropping the difficulty with just a single other person. Still failed thanks to specials and AIs being too slow to help. By now we were sick of the campaign so later I just threw it on easy mode and ran through it quick because I wanted to finish it..
Really can't imagine doing the ending on expert mode.
The first tank is okay, but then 2 of them are inside the building with no room to run and they basically corner you in. How on earth are you supposed to survive that on expert?
- Level 1 was the most interesting with the church and swimming pool. I was really hoping to see more neat areas like that.
- Spanish writing on the walls. Yes, I perfectly understand why it's there and how it makes plenty of sense.
The problem is that a majority won't be able to read anything on the levels walls which has us miss out on lots of writing.
- Helicopter flies into the building at the end. Lol wat.
- L4D2 survivors. (Just personal opinion.)

Conclusion:

This is the final version? Then that's a shame because it isn't perfect.
Good campaign, but the optimization needs fixed and the difficulty needs looking at.

Other than that, it's wonderful. Very very impressive campaign. It's one to really "wow" you.
The introduction to the whole campaign in that church was just really awesome.

I'll give it a 9. If the lag and difficulty were fixed then a 10.

Pros:

+ Looks pretty good. Visually looks well-made. Has some nice areas. A lot of places are just put together well like the insides of buildings. 
+ Quality map design
+ Neat areas like the theatre, bowling alley, and stadium. More of these would have been fun. The river section was nice too. Reminded me of The Passing campaign in a darker style.
+ Bots seemed fine.
+ Enough events to keep it exciting
+ Good map diversity to keep things interesting.
+ Mostly entertaining
+ Good length. Doesn't drag on. Not too short.
+ Nice use of dialogue!
+ Good weapon selection including melee.
+ Has a great L4D atmosphere.
+ A+ easter egg. Was so awesome.
+ Overall, the map is almost flawless. It feels complete and as professional as the official campaigns. Very well made. Tons of hours went into it for sure.

Cons:

- TOO MANY SPECIALS.
This was definitely the only bad thing about the map.
There were way too many freaking specials. Wow, they just don't stop coming. There's never a moment's peace.
- A bit samey samey. A lot of the map looks very plain and ordinary. Might of been what they were going for as it resembles the L4D1 maps looks for most of the levels, which in that case they did a good job.
Some parts do look nice while still being this way though. I liked the blue tinted town on the river. 
- One minor invisible wall and that's at the part on the river when waiting for the boat. You can go over the bridge and fall, but after starting the boat you can no longer go over until it comes. It should be more consistent rather than a wall randomly appearing then disappearing.
Does this help? I mean sure. You won't fall into the water on accident.
But invisible walls are never good. XD
- We don't get to go to that real pretty spot with the deer! I was real upset we didn't to go out there. I'd love to see a map made in that style because it looked great.
- L4D2 characters. I know it's a port to L4D2 so it only makes sense to use them rather than the originals, but I personally prefer the L4D1 survivors much :P

Conclusion:

Overall a pretty entertaining map that's worth a playthrough. I had heard about it for a while. The name didn't appeal to me at all which is probably the main reason I didn't try it! Glad I finally did though.

Good one to keep in your collection.
It'd get a 10 if it weren't for the specials and maybe tightened up just a little like with the mentioned invisible wall.
The deer area and L4D2 characters as well as appearance are just my own personal tastes so don't effect the score.

Pros:

+ Optimized great. Stable nearly the whole way. Felt smooth. Emphasis on "nearly"
One part of the map lags just a bit everytime I play it. Check the cons.
+ Visually looks great. The best looking map I've seen yet. Very smooth and well detailed. Also disagree with what Dannbo said about the color correction. Really hope you don't change how this map looks.
+ Awesome theme. A desert theme done without it feeling bland. Despite it being quite different than the usual, it still felt like L4D.
+ Some exciting parts like the "run to the church" sequence were a great addition. Wouldn't have minded seeing one more big thing like that.
+ Lots of rooms to explore.
+ Nice mix of both outdoor and indoor environments. Was enough of both.
+ Good level themes. Level 1 was the intro/ cave, level 2 was the town, level 3 was the main desert, level 4 had the sewers and the download center, and level 5 the escape town.
+ Nice intro.
+ Good length. Took an hour. Never dragged on and wasn't too short.
+ Very enjoyable map. It wasn't boring. Had fun going through it all.
+ Some challenging parts that felt right according to the difficulty I was on.
+ Good mix of zombie-infested areas and clear zones. There were enough breaks from all the action without it ever getting too empty. Enough specials and tanks.
+ Arrows guiding the way. Really helps.
+ Lots of rooms to go in. It's pretty clear which doors don't open so unlike with most maps - I didn't find myself constantly trying to open up locked doors.
+ L4D1 survivors. 
+ Just so awesome.

Cons:

- Jake's audio quality. 
This is the worst part about the entire campaign.
In the first map I immediately noticed his voice constantly distorting.
It sounded pretty bad.
I highly recommend re-recording his audio with a quality microphone at a level to where it isn't peaking and using a pop filter.
Condenser mic would be preferred, but any decent mic would do. Pop filter is a must regardless of the mic used.
The voice just hugely harms this map due to it distorting.
When "Jake" records, he needs to watch the meters and make sure they don't go in the red. Peaking needs to be avoided.
Same for when editing them in a DAW. 
- Bot AI seemed fair most of the campaign but there were a couple hiccups. At one point the bot got completely stuck and just stood in one spot. Eventually moved after I knocked him down twice. Another part when going up a ladder, the bot kept falling back down after getting to the top. Other than that, no problems.
- At the start of.. Map 2 some zombie heads were popping through a garage door. Not a big problem but just noting that.
- Performance drop early on in map 4. It only happens in some parts. This is the only part of the campaign that I noticed any lag issues. Friends playing with me my second time noticed it as well.
- The cave in level 1 is just too dark. I know darkness is a recurring theme, hence why we have flashlights.. But I found myself blindly shooting just to light the place up. Needs some more light in there.
It isn't necessarily bad as it is though so this isn't a must.
- I like the town in level 2, but the big empty.. river? Was really ugly and negatively effected the look of the whole town. Changing the map a bit to either have that all flat or filled up with water would make the level look WAY better.
Not expecting to see this change as I know it'd call for a lot of level changes, but just throwing it out there.
- Some was a little too easy. Specifically the last level. While I liked the escape, defending until the helicopter came wasn't a challenge. I've only played the campaign in normal so I suppose I should try advanced next time.
- The part after downloading the data isn't very clear on where to go. I understand Jake guides you the right way, but not everyone is going to keep his voice on and I definitely won't be using his voice until his audio is fixed.
- There's an invisible wall in the plane that crash landed out in the desert. 
- At the end when escaping, I noticed zombies spawning on top of the roof. They were appearing out of nowhere. They need to be more hidden :P
- Not enough melee weapons. Barely found any the whole campaign. 

Conclusion:

Overall this is by far the best custom map I've ever played. It's as good as the official campaigns, if not  better.
Really great theme and the visuals are nice. Never feels boring.
I can definitely see myself suggesting it to others to download. Played with AI for the first 3 maps and then 2 people joined in. Would be much better with a full team of friends.

I imagine a ton of hours have went into making it and just know your work was worth it because the result is great.
Best of luck finishing up. I'm really hoping you fix the cons I mentioned in the final version.

If you need screenshots to identify any of the areas for the glitches I pointed out in the cons then let me know and I can get them for you.

For now it gets an 8, but if the cons were fixed it'd get a solid 10++++++++++++.
