Pros:

-Detail map
-Special zombies included
-AI is not too bad for a beta version

Cons:

-a long office map can be confused
-need more ammo in office area
-add more directions please
-once you open the door-officce map (First Crescendo Event), a tank and a witch are waiting for you in EASY setting
-near the end of map a car almost kill 2 AI bots.

Conclusion:

I think it is much harder to play this map in SP mode. (EASY setting)  I use pistols 80% of time because I do not know if there is ammo pile or not.  I think author can make better one in the near future.

Pros:

-great design maps
-good detail
-Long campaign only 75MB
-add uncommon zombies
-Add dialogue

Cons:

-The biggest problem is final- Coach and Rochelle run to right side of the fence, so 2 AI Bots cannot move and they do not die either.
-AI NAG. near end of map 1 saferoom (Rochelle), AI NAG. near end of map 3 saferoom (Ellis)
-No ammo supply between the beginning of map 4 and "use button to open the gate" 

Conclusion:

I cannot finish the final map because 2 AI canot move and die.  I try to kill both of them, but both AI are invincible.  I think 2 AI are blocked by the fence.  Only 1 AI Ellis follow me to the truck, but it is no good.  I really love to play this campaign, but the final map is unplayable.
I will do the second review if author can fix these issues.  (v.1.0) 

Overall, I really enjoy this campaign from map 1 to map 5, please fix the final map first.

Pros:

-nice maps design

Cons:

-too many unlimited zombies 
-take 3 mins to load map 2, WTH
-AI threw away tire 2 weapons in map 2 safe room
-No direction,cannot find the processor in map 2
-AI Nag. cannot climb ladder
-Almost no zombies between the beginning and the end in map 1
-Magic tunnel in map 2: one side is night time, the other is day time

Conclusion:

No direction, no time to find, because too many zombies.  this campaign encourage players use cheats.

Pros:

-nice level design
-AI Nag. is good
-5 maps less than 40 MB
-uncommon zombies

Cons:

-may add some melee weapons

Conclusion:

This version 3.1 is better, I like this campaign.  Great job.

Pros:

-Excellent maps 
-Uncommon zombies
-Great level layout with AI Director 2.0
-excellent AI bots NAG

Cons:

-none

Conclusion:

This is one of the best L4D 2 campaign, I recommand for everyone.  you will like to play it again and again....

Pros:

-great campaign design 
-nice songs from midnight riders
-traps
-a lot zombies to kill
-AI bots great
-sentry guns
-many ammo piles and first aid kits 

Cons:

-2 AI bots already in the saferoom before the 2nd gate open completely.(Homeland Security Map3)- If player stand in front of 3 gates on SP campaign, not stay inside the security room.
-may be too difficult for SP mode (too many gas cans to collect and too many zombies) 

Conclusion:

For "EASY" campaign, total 7250 zombies killed, and player needs to collect "16" gas cans in the final.  Overall, I would say this is a great campaign.  Worth your time to play.

Pros:

-Better Intro than pre. Version
-Bots Nag. great

Cons:

-3 rd tank come from no where on final map?

Conclusion:

Overall this is a great campaign for L4D 2.  I still prefer last version of final because v.3.1 final map is too hard even on easy difficulty.

Pros:

-great design maps
-feel like Valve made
-Bots nag. excellent.

Cons:

- invisable vehicles-1 truck ,and 1 car near Riverside sign in Map 3 (I only can see vehicles' window. 

Conclusion:

Great campain for L4D 2 plyers, recommand for every one to enjoy.  I hope authers can fix that invisable vehicles.  My review is based on my SP experience. (Dec. 21,2010-V.2.0)

Pros:

-great design campaign including city, village, forest maps
-AI bots are excellent
-Ammo piles well placed
-Well design difficulty level

Cons:

-only one small area a little similar to No Mercy part.

Conclusion:

I like this campaign because I can not find AI bots problems and this campagn mix all different kinds of maps.  my review is base on SP experience. (Nov.29,2010)
I really would like to see more L4D campaigns from this author.  Excellent work!!!!

Pros:

-a great design campaign
-i really like them map 1- map3

Cons:

-start from Map 1 , 1 bot takes so long to take first aid kit
-Map 4, near final area, 1 bot can not Nag after leaving sewer system.
-Map 4, 1 AI bot try to go back tunnel again and again until he/she die!!!!!!
-1 bot CAN go under military vehicle and bot can still survive????

Conclusion:

These bugs still there, otherwise this is a bug free campaign for L4D 1.  I think these bugs must be fixed.  I hope author can release newer version soon.
I will suggest this campaign is only good for human teamates so far. ( Version V 2.69 )
This review is base on my SP experience. (Nov 28, 2010)

Pros:

-good maps (map 1 , map 2)

Cons:

-map 3 floating hunter, zombies
-map 3 invisible objects, hard to move around
-map 4 invisable radio
-poster need improvement
-map 3 , and map 4 too silimar to valve's "The Parish"

Conclusion:

PS: This review is base on my SP experience.

Pros:

-great campaign design
-AI bots not too bad

Cons:

-zombies bodies DISAPPEAR !!!!

-If I shoot the zombies near the wooden fence in the city maps, there is no blood on it.

Pretty good L4D campaign, it is strange no ammo pile for the final escape?  This review is based on my SP experience.
if the author can fix that, that will be perect.

Pros:

-good maps design
-raining weather
-5 maps campaign

Cons:

-Map 5 in the saferoom, yellow colour wall near 4 first aid kits
-final map (5) no sound when I try to call a chopper

Conclusion:

overall it is still a good map, I hope author can fix that.(v.1.1)  
ps: My review base on my SP experience.

Pros:

-good maps for L4D1

Cons:

- Only 1 AI has difficulty to climb the ladder in order to escape in the final map.  it takes 10-15 seconds to do that job. (PS: I use cheats, otherwise AI will die for sure)

Conclusion:

Great campaign for L4D.  This review base on SP campaign experience. I hope author can fix that bug. (v.4.0)

-In the subway station (city hall map), the wall colors -mix white and black near ceiling part

-less ammo piles

Conclusion:

Over all it is still a good campaign. (v.8.0)  This review bases on my SP experience.  it is a long , but a great campaign I hope authers can improve and fix that 2 issues.  Almost a perfet SP experience just like Valve did. 

Pros:

Cons:

-AI bug, map 4 on the roof(hunter attack me all 3 just stand there)
-no ammo pile near sewer entrance (end of map 3)
- no pipe bombs and molotovs in the final map 
-where are the police cars in map 4,5? (there are so many security officers) and too many school buses

Conclusion:

very good campaign, easy difficulty -I killed 4626 zombies, I replay the map 4 because the AI bug on the roof map.
This review base on my SP experience (V.7.0).  If auther can fix AI issue, this campaign will be so close to Valve quality campaign.

Pros:

-nice maps
-good design in the final map

Cons:

-strange colors appear in map 4

Conclusion:

Strange colors appear after I get inside the ship.
Overall this is a good campaign, if auther can fix that, it will be one of the bset campaign.

Pros:

-nice 3 maps
-L4D 1 survivors in L4D2 environment

Cons:

-FPS drop, and almost freeze 1 second
-less weapons in map 1, map 2
-need more ammo piles please

Conclusion:

it is a good camapign, but I try the SP campaign first time, the game will slow down sometimes. I think this is the big problem.  And blue light around zombies.  I think authers can fix both things.(v.2.0)
ps:3 AI are pretty good so far.

Pros:

good maps design,music

Cons:

In the 5th map-(dead Storm),not very far from the safe room) I leave the sewer, I see parking lots and get some ammo,just leave the parking lots, smoker attack me, all 3 AI teammates do noting just stand there. please fix that

Conclusion:

I believe you can improve version 13.0. 
I enjoy play the SP campaign in this map, Dead train map is hard (in normal mode)-too many zombies.

Pros:

good Halloween campaign , music.

Cons:

- 3 rd map, 1 AI bot can not move.
-too many zombies in the final (Normal level-total kill 2900 zombies)

Conclusion:

This is beta v1.1, it is a good Halloween maps.  I think Dr.Boo can do it right. (AI bugs)
