Pros:

Overall really impressive level design (light & shadows, color correction, credibility and story). Good amount of weapons and items. Absolutely makeable on expert (but ... see cons). Playable on many different modes. Good navigation etc, etc...

Cons:

I have played this campaign more than 5 times but my team and I never made it through the finale on Expert difficulty. We are playing on this high diff. alot, but there's no where to go or camp succesfully. I would like to beat this campaign on Expert, though, but I can't. No real points pulled from that con, though :)

Conclusion:

One of my favorite campaign, and believe me: I have played around 60 custom campaigns so far. Although I don't know why I haven't reviewed this yet and it's been a while since I played it last, I still want to say that it was one of the best designed maps I've seen here so far. Keep on making excellent maps!

Pros:

+ custom skin for my favorite SI, fit's perfectly into L4D and into natural habitat of the Hunter :D
+ he now has a belt.
+ custom mouth

Cons:

- took you ages to release

Conclusion:

Perfect for everyone who wants to have a cloaked (and maybe even more realistic)  Hunter. I'm keeping this mod!
...What, it's a Beta? What do you want to change? It already feels complete.

Pros:

+ different start as in usual campaigns
+ great light ambient
+ custom sounds and music
+ lightning strikes and meteors, flame throwers, collapsing building etc.
+ custom particle effects

+ after version 2 I didn't recognized the previous walkway. total difference!
+ C4 to blow up a barricade

Cons:

- bot felt down the building to 1HP health in the middle of the helicopter scene, and died by the fire (could be rescued due to rescue closet at the interior)
- maybe a little too much epicness for my taste, e.g. the military finale with too many supplies, throwable items, weapons and basically everything. also the ending helicopter scene was too much imo (color correction, music... less is more)

Conclusion:

I really liked the lights and cubemaps in your 1-map-campaign. Everything else has been said before by previous poster. Really amazing work.

Pros:

+ a Hunter in your Survivor Team!
+ (nearly) flawless replacement

Cons:

- just some minor cons but not worth listing

Conclusion:

I downloaded this mod about 2 months ago and still use it. Highly recommended for Hunter fans who want a own Hunter in their team.

Pros:

+ constructive maps
+ lightning
+ nav flow
+ infected museum
+ random weapon and item spawns

Cons:

- a bit empty in some areas
- finale cave looked not as good as the rest in my opinion

Conclusion:

I've just played your campaign with one friend and two other randoms and I ...

... first I have to say that every single map is very well-thought-out, for example the infection-museum, just to mention one. Also it has great lightning conditions, due to this we knew exactly where to go. Some more details could've been involved but I don't think that every area has to be full of objects and stain details just to look "full" or "better". Also I noticed random objects/alternative prop spawns. Because of the great environment we were able to defend well and only had to restart three or four times at the crescendo event in the Museum-level because of the never ending hordes, but we even made it on expert and moved on very smoothly and fast. At the end all of us got into the rescue vehicle.

The finale cave-area looked a bit missplaced and not so well done as the interior, but thats really the only thing I can think of as a negative point, even as a mapper myself. We never noticed any sorts of lags due to bad performance nor I discovered any misplaced textures or other minor bugs. At the end I have to say that the sceenshots dont look as awesome as the actual maps!

We had great fun playing it, so I give your campaign a 9.5!

Pros:

+ very long, well detailed and nicely lit maps
+ you almost instantly know where to go
+ you can run fast through the streets, buildings and undergrounds
+ challenges! (crescendo events, tank spawns in every map)
+ I liked the idea that not every area has to be full of stain-decals just to look detailed. for example not every warehouse looked like theres a big infection going around.

Cons:

- too much ammo, supplies (medkits everywhere!) and throwable items, but recommended in expert mode (or maybe it was just the server)
- crescendo events are almost too hard; too many hordes, but makeable even on expert!

Conclusion:

My mate and I had to try your campaigns 3 or 4 times within 3 days. We played like 2 hours every session or more on expert to get through your levels but hardly made it. Thats nothing bad; we LOVED it! We had so much fun going through your campaign that we didnt care about the difficulty. We enjoyed the challenging panic events, tank spawns and the finale. We both died like 30 times but we died with big laughter :D After 3 hours and 53 minutes we can do nothing but say that this campaign was just GREAT!

Pros:

+ moving train
+ toxic water
+ different locations
+ enough supplies to survive even on higher difficulty
+ well lit areas, you easily know which way to go
+ custom finale sound and music

+ Im not sure about that pushcard in map 2 or 3, I think. maybe an easter egg?

Cons:

there are a few minor bugs that fell into my eyes. some may be just my opinion, but also general advices:

- the intro camera is a bit too static, could've done more dramatically in my opinion
- in second map, crescendo event by the train station, the vocalizes of the survivor sounded creepy (right near you, not actualy coming from them)
- you can jump off the main way to reach the end, unplayable area of the map (third map, out of the sewer under the bridges/highway, right before the little house with the rescue closet) you can jump on the fence and get out of there. that was funny. 

- also you forgot to put func_precipitation_blocker (or how its called) inside the tower at the finale, caused heavy dust inside it. death cam wasnt placed right
-some lights, textures and sprites seemed to be unfitting generally
- last thing I noticed was that the radio voice was way too silent

Conclusion:

All in all I gave you a 8 of 10 because in my opinion there are some tweaks that bothered me (mostly the finale). Not really a campaign I'd LOVE to play again but still a better one then I could ever create at this time. The only con-points that fell into my rating were the last three. Nice campaign overall!

Pros:

+ long and dark maps
+ very nicely detailed ambience
+ you easily know where to go due to well placed lights
+ SCARY MOMENTS! (scary face, twice. giant baby face in dark sky. moving tree. changing pictures and doors. never seen that before! creepy sounds. VERY well done!)
+ hints to other amazing campaigns :D (movie poster)
+ not too easy, not too hard - enough ammo, supplies, throwable items etc.

Cons:

- survivors could say a little more/more story needed
- in finale there are way too much special infected. hard to make it through on expert, only two survived (but maybe it was only the server/director)
thats all I could complain about.

Conclusion:

I gave this map a 10/10 because my mate and I were really surprised by your map. We played it on expert and despite we had some trouble during the first (very long) map, it was all in all very smooth to play. I'd recommend this campaign to anyone who plays addons as well. High replayability! Thanks for this campaign!

Pros:

+ dark and foggy Silent Hill feeling
+ scary witch-scene in elementary school
(these are the only pros in my opinion so far)

Cons:

- lack of supplies and weapons overall
- bots do not pick up any items/supplies
- absolutely no story/you don't know why the survivors got there
- I missed the typical Left 4 Dead soundtrack or at least minimalistic background-music
- you don't know why you have to pick up this or that item to solve puzzles if you haven't played the series
- poorly lit areas

- player (and bots) got stuck in the beginning of third level in that room where you can fall down and die. we had to restart the whole map after waiting minutes to anything to happen.

Conclusion:

I tried to make it through your campaign with a mate of mine for the second time just now and I really have to be honest ... it wasn't really fun to play. We heavily made it to the third level. We stuck there again because we don't know where to go. Poorly lit areas didn't help us to find the way. I know that the Silent Hill series are mostly dark, rusty and mysterious but even there are some areas that show you the way.
Also we often died on higher difficulty because of the high special infected ratio, which just was annoying. In my opinion this campaign can not be passed on higher difficulty.

Nonetheless we will definetily try to make it through your campaign but I'm afraid that 3/10 is all I can give.

Pros:

+ massive amount of details
+ very realistic feeling, you can actualy notice that you've kept to reality
+ maps are not too large, just fine
+ very, very well lightened

Cons:

- the airplane sound is indeed too annoying and loud
- the fourth map has a displacement error, you can see through the map
- the sound at the finale- too loud
- there's a texture error before you enter the main building in the last map
- did I mention that you are trolling us with the finale sound? :D (but still: 95/100)

Conclusion:

All in one it's the most open world campaign my mate and I were playing since.. ever. We really liked this idea instead of that typical one-way-maps. For my taste it was a little bit overcrowded, almost too detailed (the rain, things/details in every corner, etc) but we've made it in more than one hour on expert. I would definitely recommend it!
