Pros:

Long winding levels
Lots of areas to explore
Hints along the way

Cons:

May areas felt repetitious
Finale was "average"

Conclusion:

A very well made map with some interesting areas not found elsewhere (jumping across the chasm for example). This really should be in your addons folder. It looks great and plays great. Clearly stated that this is in beta so I'll hold back on a lengthy review for now.

The one area that I felt needed some touching up was the finale. It was easy to hold out and the tank got stuck both times... you just need to light him on fire and walk back for ammo. By the time you return he's a gonner.

Can't wait to see this evolve into an even better campaign. Thanks!

Pros:

Lots of areas to explore - didn't feel confined
L4D1 "feel"
well planned layout

Cons:

Lack of detail- felt empty
Finale was a bit easy
Lots of easily found supplies

Conclusion:

It's not often you come across a map and say "oooh, this is gonna be good" ... Perfect Hideout 2 is one of those maps... IF a bit more detail is added. As-is the maps feel unfinished but expansive giving the over all impression that it's very empty. All the major elements are there to make an interesting and playable game but not enough to allow for the emmersion a top-notch map generates. Add some props, a bit more "life" to certain areas,  maybe a dynamic path and hide some of the supplies to encourage exploring all those areas easily by-passed and you're almost there. 

The finale was a bit easy but i didn't really feel cheated. The lack of detail and the lack of an ending challenge just says, to me, a bit more work is needed before this one can be called "done".

Thanks guys, really awesome map. Can't wait to see it completed!

Pros:

* Wow, just wow.
* Amazingly detailed and rich map
* Faithful to the Helm's Deep battle
* Replayability
* Forces teamwork

Cons:

* Random glitch now and then. (NPCs occassionally not spawning and it seems one person every map freezes when running towards Gandalf )

Conclusion:

This truly is the best Survival map out there. All the other reviews sum up why very nicely so I won't waste your time repeating things you can read elsewhere but I do want to say this to the new players. Please please please listen to the experienced players on this map. To survive to the end you have to work together and complete each section in an organized manner. This isn't your typical survival map, you can win but you can't do it without everyone working together. 
To the authors- thank you for this incredible map. This is the highest scored map out there and it's for a good reason... it kicks ass!

Pros:

Interesting / Creative Levels
Nice use of single pick up weapons

Cons:

Needs a few more ammo dumps
Bots sometimes got lost
Finale is way too hard

Conclusion:

I remembered playing a few maps of this camp back during the D1 days, I think it was incomplete as I don't recall the finale there. The port to D2 is pretty nice. The levels are challenging and the game play solid. Never were we bored running through the camp, the level design and atmosphere is great. We did find that there were times when we had all run our guns dry so maybe a few more ammo dumps or weapons scattered around  might be called for. The one part that really was a downer was the finale; it is simply way to difficult even on normal. We played 3 rounds on normal and even tried easy but could not finish. We simply gave up after 4 rounds of having our hineys handed to us. The major problem is that the cans are scattered in remote locations, while that is not bad on it's own it is compounded by the location of the generator. It's up 3 flights of steps basically and running the cans that far facing hordes and specials is difficult to say the least. Another flaw with the finale is the level is very cluttered giving hordes and specials the ability to spawn at point blank range basically. Top off those 2 previous attributes with a lack of health supplies and you are in for a rough ride.

In conclusion I see no major flaws with 3/4 of the camp... it's the finale that takes the biggest bite out of Dark Blood 2's score. It has the potential to be awesome but I don't see it being in regular rotation in it's current form

NOW- inigmontoya: You are correct, the rating system is broken and you are proof of that. Randomly giving a campaign a 100% just because someone else's review ticked you off. Good show.

Pros:

Beautiful Environment
Unique loactions 
Some "wow" moments
Some "oh carp!" moments
solid game play through out

Cons:

Door on map 1 (was that just us?)
Boat is pointless and abusable
Fence jumping to bypass car and witch
Landscape seemed a bit hap hazard at times

Conclusion:

-To DaFish: I have no idea which campaign you were playing, it obviously wasn't this one. 2EE is a solid campaign through and through, very "playable" and certainly fun. There were more then a few surprizes along the way that made the campaign standout. As some reviewers stated before, 2EE is tough but I didn't find it overly hard. There was a nice balance of action and supplies along the way. Some of the maps were a bit "short" but the over all action made up for that. The only map that felt kinda "flat" to me was map 1. All the others had interesting elements but map 1 felt a little like a walk around the block. Also on map 1 we encountered a door that couldn't be opened... it actually took a pipebomb to blast our way through. That was either a glitch or we just didn't "get it". We were being swarmed by zombies and I don't think anyone tried to whack it open with a melee weapon. On map 3 (I think) 2 of our players were able to jump over the fence to the saferoom avoiding the car alarm and witch. The boat event seemed a little pointless and glitchy. The ride is very short and basically if you stand in front of the boat you just get pushed along without fear of being mobbed by CI or SI. 
Other then a few minor issues 2EE is a standout campaign with really stunning enviornments (1 player said "are we on Pandora?" referring to the movie Avatar) that felt a little chaotic to me at times, well spaced out events (unlike some other maps which seem to always have an alarm wailing in your headset) and some really neat-o surprizes along the way. 2EE is a solid 8/10 and worth downloading.
