Pros:

Map 3
+beautiful indoor lab design, very detail in those rooms
+cool ending cutsence
+Custom sound
+Chemical

Map 4
+Silent Hill style texture
+Silent Hill 3!!!(&4?)
+Half Life 2 map design(Nova Prospekt?)
+Trap & puzzle! XD

Map 5
+Airscrew from HL2!

Overall
+enough supply
+challenging, but not unbeatable
+In most of the maps players really need to pay attention to search for roads

Cons:

Map 1
-too many horde events and SI(especially the horde event before the bridge, that really don't make any sense), that really lower the interest for player to explore tha map
-tier 2 weapon in Map 1, but considering the annoying horde events and SI, that can be understood

Map 2
-still plenty of horde events, which are still annoying

Map 3
-horde events are still annoying
-the way to destory the power cable seems to be too complicated
-the ground floor of the lab seems a little bit empty

Map 4
-AI had difficulty for climbing down the ladders, but as far as they are not
harmed, it should be okay
-Supply seems to little in the part of alarm puzzle

Conclusion:

Explain a little bit more about the horde events...

Except the fixed horde events mentioned in Map 1, all the horde events in the cons refers to the ramdon horde events. I mean, the frequency of ramdon horde events in this mod is too high, worse, most of the maps need players to search for roads carefully, that really makes the frequent ramdon horde events become extremely annoying.

Overall I enjoy this campaign, it forces player to search for road carefully, the dark environment really makes a good atmosphere and make the campaign more challenging, bots' performance are not bad, no major bugs, enough supply, elements from HL2 and Sillent Hill, these factors make this campaign a nice one. It will be better if the frequency of random horde events can be lowered.

Pros:

-tasks, not just push botton or wait
-plenty supply
-natural disater
-detailed environment
-song!
-nice atmosphere
-ghost house!
-Scary moment!
-dialogue
-Value :0

Cons:

-Some intructions are not so clear, like the gas from l4d1 survivors, at first I have no idea about what to do next

Conclusion:

I can see afford in this map, creative and challenging, this map  deserve the rating, I look forward to another high-quality map made by you.

Pros:

-Chinese theme
-songs
-interesting ending

Cons:

-extremely lack of supply, especially there is no health kit, even pills in the rescue area, only defibrillator
-the ammo pile is too near the "stair", making bots always get caught by the SI
-I don't see much connection between your title and the game (but this is not a big deal)
-I don't think there is a story...
-you add cut scenes but you don't freeze the infected, in some situations that can be a problem

Conclusion:

This campaign has potential to be a better map, but now it really need to get some improvements.

Pros:

-fair challenging
-enough supply
-good length of each level
-overall bots' performance is not bad

Cons:

-the texture(but it is okay as this is only a test campaign)
-no story or dialogue(same as above)
-some bots issue, mainly on ladder glitch
-nothing impressive

Conclusion:

Overall it is not bad, but if you want to continue to work on this map, you may have to consider about adding story, or more tricks, cause though it is not bad, it hardly impresses me.

Pros:

-original
-very detail and beautiful
-nice texture
-enough supply
-plenty area to explore

Cons:

-random weapon spawn in the beginning, tier 2 weapon included
-too clean(I mean too few corpses or bloodstain) for an apocalypse situation(especially for map 1 and map 3), look like people turned into zombies in a sudden, hard to make sense if there is a CEDA station and the military is here(or is there an explanation in the beginning radio?)
-glitchy ladder in the lift in map 3, forcing me to kill all the bots in order to proceed
-in map 1 SI spawn in the other side of the fence but they can't cross it and stuck there
-one event in map 3 doesn't make sense, why the handcarts have to be pushed? Can't it be pulled backward so that there won't be any noise?(Or I misunderstand or miss something?)
-the finale, as other players said, too easy

Conclusion:

 This is a fascinating campaign with beautiful texture and I can see your hard work in it, the campaign is challenging  but with enough supply except the finale is too easy, I think it will be more challenging if zombies come from top side in the finale.

Pros:

-realistic
-a feel of playing Half Life 2
-epic sound
-nice animation

Cons:

-replace the axe's sound

Conclusion:

This mod is very awesome, it makes the crowbar become more attractive to me, yet the only con I mentioned really makes this mod become imperfect, so I really hope that you can fix that con. 

Pros:

-very, very, very big
-very detail
-big area to explore
-professional level and space design, with only a few arrows pointing the direction
-challenge of saving ammo, few melee weapon only until map 3, but also with appropriate amount of supply
-underground maze, challenging but not unbeatable, also with horrible atmosphere
-puzzle (pipe in map 2)
-very overwhelming and long finale with just enough supply
-the ending......

Cons:

-For the finale, it is fine to play with human, but not very good to play with bots as they don't know how to save their ammo, maybe add a few more guns or ammo piles
-More pills or adrenaline shot in the finale will be better 

Conclusion:

I can't believe this is your first campaign, it is very good and challenging.

Pros:

-funny dialogue
-intro
-attempt to make a scary atmosphere
-ghost?!
-creative, appropriate and funny horde event
-plenty of supply materials in map 1-3

Cons:

-map name...not in order
-nav issue in map 3, bots cannot get back to saferoom, once get down the ladder
-floating material in map 4
-spawn outside the saferoom
-bots have difficulty to pick up material in map 4 
-invisible wall in the castle to the lower level
-still same question with the finale, can't escape even I am on the airship

Conclusion:

I love map 1-3 very much, especially the forest, "ghost" and cross-river event, but map 4 disappoints me. I see no reason to insist of using the map from the Complex, now I miss the factory ending, at least that map doesn't have so many problems. 

Pros:

-the design of map 2, quite creative.

Cons:

-no intro & dialogue
-bots have difficulty to pick up materials
-fps issues in map 1
-no apparent reasons for horde event in map 1
-invisible wall in map 2
-what the hell of the elevator event in map 2 ?! Nothing happen even I press all three switches! Is it a puzzle that I need to solve in order to proceed?
-no pills
-ONLY melee weapon is katana in map 2
-serious nav issues in the finale, SI stuck, bots can't get aboard the airship
-funny, even I get aboard the airship when all bots died, I am not rescued

Conclusion:

Well...there is plenty of rooms for this map to improve. 

Pros:

-Glowing eyes with different colors
-Facial expression is more chilling
-Look madder than the original Miku

Cons:

-The sound become weird when I approach her in day time(it may be my fault)

Conclusion:

I love the GlaDOS Styled Miku wandering around in daytime, it looks more dangerous! It is a pity that the sound become weird when I approach her in daytime i.e. loud_angry_little_witch and lost_little_witch, but that may be my own fault as my l4d2 version is not the latest one and I installed the Miku witch before. All in all, this is awesome!
