Pros:

Original and creative concept
Length of the campaign was just right
Interesting stuff to see (boomer hanging from the ceiling lol)
Challenging

Cons:

Easy to get lost
The finale...sigh

Conclusion:

Okay, it may have taken me a while to complete it and finally post a review on it, coz I for one never managed to find the time to play through the whole campaign at one shot, and also coz...well, I had a tendency of failing halfway (the disadvantage of playing with only three bots to help you lol).
Especially at the new Witch area, it took me many many tries before I finally managed to get past that part.
But at least it proves that this campaign is challenging, and I love a good challenge.

After playing through so many other custom campaigns, this campaign was like a breath of fresh air really, and it really was a welcome change from the conventional campaign, where you just kill zombies along the way to reaching the next saferoom, to the next one, on and on before finally escaping...bleah.
The unique-ness of this campaign really makes it stand out from the others, and that is definitely one of its major plus points.

There were a lot of mini-events too (I believe you call them easter eggs?) that happened during the game that added a nice touch to the campaign and really helped stamp down this campaign's reputation as a truly unique and outstanding one.
I shan't go into detail on this part so as not to spoil the surprise, but do look out for them! (like the one mentioned above, haha)

However, sometimes everything just gets real messy and you have no idea where to go. There isn't like any fixed direction set for you to follow and you end up running around in circles. Especially in map 1, after you enter the compound it's just like a huge mess of metal and debris. Add that to the dark environment, and you're in for a frustrating time.

Anddddd the finale. I personally felt it was a letdown really, after just going through what was actually a pretty decent set of first four maps.
I have mixed feelings on the sentry guns, coz although I applaud such a unique idea in L4D2, I felt they were so good at what they do (killing zombies) that it really just took an edge out of the finale, like it wasn't as challenging as it was made out to be in the end.
The lack of Tanks too in the finale left me kinda disappointed, though I do love how that one Tank made its appearance in the finale (totally wasn't expecting that, haha)
Also, I know that that is one huge ass helicopter that's going to bring us to safety, but still...so many gas cans needed?
Okay, maybe the number wouldn't be such a problem, IF they weren't so spread out literally all over the place. I think the finale area is waaaaaay too big, and transporting the gas cans to the chopper gets super annoying after a while with the constant long trips back and forth. Basically, I think everything would actually be fine if the size of the finale area was reduced. Correct me if I'm wrong, but I think the distance you would cover during this finale transporting fuel cans as compared to that of Dead Center is definitely much longer. And at least in Dead Center you are able to drop the fuel cans down to your escape vehicle to avoid the inconvenience of having to push your way through say a whole horde of zombies with a damn gas can.
If the finale can be improved, this campaign would definitely be one of my faves.

8.7/10. I would really really love to give it more, so please give me the chance to do so, coz right now I really just can't find the reason to.

Pros:

-Kick-ass concept
-Originality and creative ideas
-Length of the campaign was justtt right
-Lovely cut scenes!
-Carrying the cola in this campaign isn't a redudant task (there's actually a purpose for carrying it, not just for fun)
-Best.
 Finale.
 Ever.

I could go on forever really.

Cons:

I really really can't for the life of me find anything wrong with this campaign. Honestly. I've played and re-played this many times and enjoyed myself thoroughly each time I did.

Conclusion:

I always look out for custom campaigns which are highly creative and original, something that really makes it stand out from the others, and this is definitely one of those.
I mean, airstrikes? Killer gas? Awesomenessssss.
And I also like how you put to good use the cola. I don't really like campaigns which leave us with the cola/gnome with no real reason to bring it all the way to the end or even carry it in the first place, so kudos to you for that too.
And your cut scenes!! I can really tell that you put in a lot of time and effort into this awesome campaign, so it's nice to see such a wonderful outcome from it (:
AND YOUR FINALE! I've always preferred the finale for The Parish over all the others, so naturally this finale would strike a good chord with me. But really, thanks for not potentially ruining a perfectly good campaign by making it a 'scavenge' finale, like what happened with Military Industrial Complex II.

On a side note, personally I would've loved to try out starting the level with the whole team split up, not just in pairs (like what it was like before the most recent update), but I understand why you did what you did, and it's not really that big a deal anyway, so all's cool.

All in all, truly one of the few flawless campaigns on this website.
Full marks to you sir ;)

Pros:

Creativity
Originality
No fixed route to follow (many parts offered two ways to proceed further into the level)

Cons:

None whatsoever, except for the thing I mentioned below, which can't really be considered a con.

Conclusion:

If I didn't know any better, I would've thought that this was an official Valve campaign.
That's how awesome this campaign is.

But I agree with the review below, there should be an indicator showing players where to go at the helicopter part. From the part where I called the heli to when it crashed, my health dropped from a healthy green to about 14 if I remember correctly (which is quite a lot considering I was playing on Normal difficulty), all because I didn't know where to go and the zombies kept mobbing me.

Other than that, this was a flawless campaign, and I can't wait to play it with my friends!
9.9/10 (10/10 if indicator is added at the heli part)

Pros:

Love the intro
Exterior design was nice (area before entering Fort Noesis)
Wasn't too difficult to navigate

Cons:

Some invisible stuff
AI refused to leave the saferoom? [Map 2]
AI refused to take stuff (medkits, weapons, etc.) [Map 3]
Infected spawning out of nowhere??

Conclusion:

I'm not good at all the technical terms (I always go huh? when I see people talking about the textures of the map), so I'll just say whatever comes to mind that affected the gameplay experience.


There were some invisible boxes I think? Couldn't tell since I couldn't see it, only realised it when for some reason I found something blocking my way though it seemed as though nothing was in front of me...didn't affect the gameplay, but just thought that I should point it out.

In map 2, Rochelle refused to leave the saferoom, so I just went on without her with the other two AIs. Reading the other reviews, it seems as though this has only happened to me, so I don't think it can be fixed? I'll play the map one more time again to see whether it happens again. (she suddenly appeared beside me about halfway through the map though; thank god for bot-teleportation)
Oh, and I love how the second safehouse was a lift. Yeah I know it doesn't really make much sense to put a safehouse door in front of lift doors, but kudos for creativity ;)

Map 3 seemed to have the biggest problems. The smaller issue was that in the area outside the lift, when I was healing myself with the medkits provided on the table in the corner of the room, a whole horde of Infected suddenly just appeared in front of me, like literally, as though they just teleported there or something ._.
I dealt with that okay, but still, it just...it shouldn't happen y'know what i mean? Yeah...

My biggest gripe is that in the entire Map 3, THE AI REFUSED TO TAKE ANYTHING! Be it pills, medkits, weapons...I dunno why, they just didn't! Even when they ran out of ammo, they just switched to their pistols instead...am I the only one experiencing this problem?? I guess this would only be a problem if you play alone when trying out new maps, like me =/

But on a more positive note, I felt this map was pretty well-designed! I especially like the beginning of the map, like the intro and the design of the area outside Fort Noesis. I really wish you could expand that more, like maybe an additional level where you'd have to maybe go through the forested area first before reaching Fort Noesis. Yeah, 4 levels instead of 3 would be awesome =D
Also, not once did I get lost, so yeah, kudos for that too! I'm not sure what you call it, you have...great mapping skills?? Yeah ;D

Overall I think this is a campaign worth downloading! 8.5/10 =)
( will give a better score if my suggestion of an additional map is taken into account and realised ;) )
