Pros:

Great looking animations
Proper FOV
Better then the default animations by far

Cons:

None

Conclusion:

One of my favorite mods, I can't play the game anymore without. :-)

Pros:

Great design
Nice custom music and sfx
Day to night cycle
Unique locations

Cons:

SI seem to have problems navigating the maps
Too many ammo spots throughout the first 4 maps
Unbalanced campaign overall, first 4 maps are rather easy yet the finale is incredibly difficult.

Conclusion:

This campaign has some great design, very unique locations, a gorgeous day to night cycle and some nice custom music and sfx to give it a excellent atmosphere. However it also seems to have some problems. The minor problems are that the SI seem to have some problems navigating the first 4 maps. They often get stuck. There's also too many ammo spots around in the first few maps, which makes some panic events a bit too easy.

The biggest problem is just the sheer unbalance of this campaign overall, again the first 4 maps are quite easy, plenty of ammo, corner camping during many crescendo's (running crescendo's exempted of course). Yet the difficult truly sky rockets in the finale, which is even tough on easy difficulty. It just doesn't make sense and needs fixing because this gonna irritate a lot of people, it just seems unfair in a way. Best way would be to increase difficulty in the first 4 maps and then making the finale a bit easier.

Pros:

Visually stunning
Great attention to detail everywhere you look
Well thought out level design
Fantastic atmosphere
Unique locations
Much re-playability due to a lot of dynamic pathing

Cons:

Finale needs a bit of work

Conclusion:

Already one of my favorite campaigns. The visual quality here is stunning! There's a great attention to detail everywhere you look and the level design itself is top notch as well. The entire campaign is full of atmosphere due to the very unique locations. Lastly there's a nice amount of re-playability due to lot's of dynamic pathing that's been added.

There a few minor bugs but they are hardly worth mentioning. I'm assuming these will be fixed in new updates anyway. The only thing that could use a bit of work is the finale. The map design itself is great but I feel lot's of the hotel is not being used as the finale is quite easy to complete. Gas cans already spawn before actually starting the generator, which realistically makes sense of course but it does give the players the chance to gather them all before they start, then pour them all in to allow for a quick getaway. It's a bit of a shame seeing as the map is gorgeous to look at and I feel it's not being used to it's full potential.

That said I don't feel this should take away from the rating so I'm giving this a 10/10 as I think it's justified by it's sheer overall awesomeness! Amazing work Surgeon! Thanks for releasing this to the community!

Pros:

Great looking environments!
Unique setting!

Cons:

Could have added a warning for the sniper in the finale map.
Way too short!

Conclusion:

First of all, this is a great looking campaign with a very unique setting that we haven't seen before in L4D! This campaign has a lot of potential put it's flawed by some odd design decisions and one major thing that makes me rate this a 7: it's way too short. Now a lot of work has probably gone into making these maps but if you have a team that's fast you can cross some of these maps in less then 40 seconds and that's just way too short! 

This campaign would be so much better if it was extended. Right now it's just so disappointing to search for supplies, explore some areas and then after a minute already reaching a safe room. It just doesn't do justice to the whole "I'm in the jungle" vibe. Apart from that I found the sniper in the finale map a bit too much. I mean it's okay if you know he's there and then have to find a way around him but this came as a surprise for all of us and we almost got killed instantly without knowing why the hell we died in the first place.

So overall I really hope the author could extend this campaign because it just feels unfinished right now. I'm sure it could be something spectacular if he adds more to it.

Pros:

Great design!
Original locations!
Challenging finale.
Well placed survivor dialog.
Multiple paths.
Plays great on versus as well as co-op!

Cons:

Needs a proper intro.

Conclusion:

People who are saying that this is a great versus campaign are not giving it enough credit, this also plays great on co-op! I really love the design on this whole campaign, the author has obviously spent a lot of time on detailing areas and it really shows! Apart from that I enjoyed wandering through original locations which I've never seen in a campaign before, the well crafted gorges for one. I also liked the fact that there are multiple paths everywhere which encourages exploration and gives some extra re-playability. Well placed survivor dialog is a nice touch as well!

The only thing that I think was missing is a proper intro but apart from that this is a fantastic mapping effort and very enjoyable campaign for both versus and co-op.

Pros:

Brilliant level design!
Some of the most detailed environments I've ever seen.
Perfect length.
Highly original with plenty of unique areas.
Heavy focus on storyline.
Challenging finale!
Great optimization.

Cons:

Finale area is quite small, not a lot of room to move around.

Conclusion:

Fantastic campaign by Kev Edwards, really one of my all time favorites! It truly deserves to be among the so called "big boys" such as Suicide Blitz, Dead Before Dawn, Blood Tracks and I Hate Mountains.

Pros:

Nice looking maps!
Great attention to detail.
Good amount of alternate paths.
Well thought out layout.
Bots navigated without problems.

Cons:

The finale, while challenging is a bit chaotic and also feels unbalanced at certain points.
The escape itself was a bit of a letdown. The elevator going down doesn't really seem like a proper ending.

Conclusion:

Another great campaign from Yanzl! I liked Carried Off a lot, especially it's grayish/dark look. Although Blood Proof looks and feels very different, it still has many of the same great features that Carried Off had as well.

The maps look very nice and there's great attention to detail everywhere. There were also a good amount of alternate paths which makes for more re-playability. Lastly I thought the whole layout of the campaign was very well thought out and the bots seemed to navigate without any problems.

The only downside for me personally was the finale. Don't get me wrong, it's quite entertaining and definitely challenging but it kind of suffers from the same problems that I had with the finale from Carried Off, it's very chaotic and it also feels unbalanced at certain points. Also I felt that the escape itself was a bit of a letdown. The elevator going down doesn't really seem like a proper ending to me.

Apart from that I liked it a lot and the campaign length didn't really bother me to be honest. Great work!

Pros:

Brilliant design!
Great attention to detail.
Unique panic events!
Nice soundtrack. ;-)
Custom melee weapons.
Survivor dialog.
Custom graffiti.
Great intro and even greater outro!
Excellent finale!

Cons:

A few minor glitches, nothing worth noting.

Conclusion:

One of my all time favorite campaigns returns! Loved the first version, now I'm loving this new version even more. The design is brilliant and with the addition of the brand new map and the nice overhaul of the other maps this campaign looks and sounds amazing from beginning till end. The attention to detail is incredible! Everywhere you look you see something that you may not have noticed before but seems to fit the world exactly, the great backgrounds included. It gives it a great and unique atmosphere.

The panic events are challenging and original. Nice use of voice actors on the first map event and the survivor dialog fits in nicely. All the custom graffiti is well placed too and it was fun reading those. The custom melee weapons are of course a very welcome addition and they look and behave great! Had a lot of fun with those as did my friends who played with me!

Not gonna go too much into the music but I think we did a nice job there lol. ;-)

Great intro which sets the mood right at the start and the outro is definitely one of my favorites! Lastly the finale is still nice and challenging and I really liked the new windows and ladders that were placed to make a bit more difficult.

Overall a fantastic campaign that really belongs with the big boys at the top! Great job Chris and looking forward to your next project, who knows, perhaps we can collaborate again in the future! :-)

Pros:

Still remains challenging after all this time!
Custom soundtrack!
Almost flawless bot navigation and zombie spawning/routes.
Design and layout are still top notch.
Very well polished from beginning to end.
Plays great on co-op as well as versus.
Epic finale!

Cons:

The balloon still looks silly.
Due to the age of the campaign, some areas don't seem as detailed anymore compared to new campaigns.

Conclusion:

One of the first custom campaigns ever, still shines! Death Aboard remains challenging, well designed and highly polished till this day. It set the standard for all the other custom campaigns to come. It was also the first to ever use a custom soundtrack. What strikes me the most is that the bot navigation and zombie spawning/routes are pretty much flawless, which is a real rarity. When zombies attack, they can literally come from anywhere and SI seem to navigate without problems. The design and layout are still top notch and the finale remains as epic as when I first played it back in 2008! Lastly it plays great on co-op as well as versus.

I really don't have any problems with this campaign but I'll admit that I never really liked the balloon rescue. It seemed silly then and it still does. I always imagined this rescue being so much cooler if there was like a submarine in it or something. Lastly due to the age of the campaign some areas don't seem as detailed anymore compared to new campaigns.

Overall this remains a true classic in every sense of the word and if you've never played it, shame on you and click that download button now! :-)

Also it receives a slightly higher rating because this is the original L4D1 version. :-)

Pros:

Some of the best design I've seen in a campaign.
Large, well designed maps with a stunning amount of detail!
Great custom content everywhere!
Interesting and well thought-out panic events!
Awesome custom soundtrack!

Cons:

None.

Conclusion:

Even though it had a difficult beta release and many obstacles along the way the DBD team provided a campaign that will go down in history as one of the greatest achievements concerning custom campaigns in L4D. This campaign provides everything you would like to experience in a L4D game. Large, well designed maps with a stunning amount of detail! Interesting and well thought-out panic events! Great custom content everywhere you look and a awesome custom soundtrack that really adds to the overall atmosphere of the campaign itself and the storyline. 

What more could you ask for? It's very clear that this team really went for perfection and they obviously delivered. Even though I immensely enjoyed Dead Before Dawn 2 and it's DC version, this one will always be my favorite version despite the fact that all versions play very different from each other. As a real fan of L4D, all there is left to say is: DBD team, you have my thanks and I salute you! :-)

Pros:

Still a great campaign in every sense of the word!
Unique and varied locations with a great amount of detail!
Great level design!
Finally a version with complete audio!

Cons:

Could still use a better intro.

Conclusion:

This might not be the original release but it's a real gem! I played this with some friends after we saw this version brought back all of the original audio. It was a great experience and it was really fun to go back to after such a long time. Night Terror is still a great campaign in every sense of the word! Why? One word: originality. That's right this is one of the most original campaign you'll ever play. Even though each map has a different setting and plays differently it all fits together for some reason, like your stuck in a dream/nightmare (which is of course the case!). I love the unique locations, also the amount of detail everywhere is still amazing after all this time, especially the Haunted Mansion. There's great design everywhere you look and it all plays very smooth without glitches. Finally we have a version with all the complete audio which makes a huge difference on a campaign such as this! 

If you have played the original Night Terror and would love to experience it once more the way it was meant to be played, now is a great time to revisit this old classic! :-)

Pros:

Nice design.
Balance seems good.
Varied locations.

Cons:

Tank routing may need some tweaking.
Could use some gas/propane tanks.

Conclusion:

Overall a nice survival map. The design is good with some good attention to detail. Some areas could still use some work but for a first release this isn't a bad thing. Balance seems good too, no problems there. I also liked the varied locations you can hold out.

One of the tanks never reached me for some reason (on the garage map). I guess this might have something to do with the routing so a bit of tweaking might help. Lastly there's a lack of gas and propane tanks which are nice to use so perhaps you could add those for a better experience.

Pros:

Still remains challenging after all this time!
Custom soundtrack!
Almost flawless bot navigation and zombie spawning/routes.
Design and layout are still top notch.
Very well polished from beginning to end.
Plays great on co-op as well as versus.
Epic finale!

Cons:

The balloon still looks silly.
Due to the age of the campaign, some areas don't seem as detailed anymore compared to new campaigns.

Conclusion:

One of the first custom campaigns ever, still shines! Death Aboard remains challenging, well designed and highly polished till this day. It set the standard for all the other custom campaigns to come. It was also the first to ever use a custom soundtrack. What strikes me the most is that the bot navigation and zombie spawning/routes are pretty much flawless, which is a real rarity. When zombies attack, they can literally come from anywhere and SI seem to navigate without problems. The design and layout are still top notch and the finale remains as epic as when I first played it back in 2008! Lastly it plays great on co-op as well as versus.

I really don't have any problems with this campaign but I'll admit that I never really liked the balloon rescue. It seemed silly then and it still does. I always imagined this rescue being so much cooler if there was like a submarine in it or something. Lastly due to the age of the campaign some areas don't seem as detailed anymore compared to new campaigns.

Overall this remains a true classic in every sense of the word and if you've never played it, shame on you and click that download button now! :-)

Pros:

Great & unique design and amazing attention to detail!
Custom props, textures, skins, everything!
Great atmosphere combined with excellent locations.
Bots navigated very well.
One of the most epic finales I've seen so far!

Cons:

Needs a proper intro.
Exiting the church on map 1 is a bit difficult with bots.
Some bad frame rates.
The outro was fairly quiet (needs more epic music and sounds)

Conclusion:

A truly awesome campaign! This is the kind of material that keeps me coming back to Left 4 Dead. The design is great and unique in every way. Every location has been thought over and the use of custom props, textures and skins is amazing. I also really liked the atmosphere of the campaign. It really felt like a post-apocalyptic Barcelona in every way. Bots also navigated very well without problems (aside from the exiting of the church in map 1, which was a bit difficult to do with bots). The finale was one of the most epic endings I've seen so far, great work!

There aren't really any cons but a proper intro would be nice to have. There are some occasional frame rate issues but I honestly didn't have much problems with that, especially compared to some of the comments here. Just needs a bit of tweaking here and there, that's all. Lastly I noticed the outro was fairly quiet sound-wise. It needs some epic music or sound effects to make it a proper ending.

Overall a fantastic and highly original campaign. The authors definitely worked their ass off on this and it shows. Keep up the good work guys!

Pros:

Unique locations.
Great design and layout!
Custom Chinese music.
Very creative take on Scavenge finale!

Cons:

Bots can get stuck at various points in the campaign.

Conclusion:

A really awesome entry for the China contest and the number one winner in my opinion. Campaign features unique locations such as an airplane and the great wall. All the design and layout in top notch and the custom Chinese music really adds to the atmosphere. The finale is a very creative and fun take on a Scavenge finale. It works really well and adds something special to the whole feel of the campaign. Great work CastorJudo! Really shows that you are one of the most talented designers out there!

Pros:

Beautiful scenery.
Impressive level design.
Great use of custom models and textures.
Bots navigated without problems.
First convincing use of train travel!

Cons:

Way too many medkits and throw ables.
Finale was very generic and too easy.
Rescue chopper was missing a pilot.

Conclusion:

A short but very impressive campaign. The scenery was especially beautiful, great use of custom models and textures. Bots also navigated without problems, as did the SI. A very nice surprise was the use of the train at the start of map 3, it's without a doubt the most convincing trail travel sequence I've seen so far, complete with lagless movement and sound.

There were however way too many medkits and throw ables present. I'm not sure if this was the director's doing or not but I played this on single player, normal and I counted at least 10 to 15 medkits in the first two maps. Same goes for the huge amount of throw ables. I also felt that the finale was very generic, a bit disappointing perhaps and too easy. That could really use some work. Lastly the rescue chopper didn't have a pilot in the seat, a minor thing maybe but it looked pretty strange.

Overall a really nice addition to the China contest and definitely one of the possible winners.

Pros:

Brilliant design!
Amazingly detailed maps.
Stays true to the original even though it provides a completely new experience!
Custom melee weapon and tank skin!

Cons:

Couldn't find anything I didn't like.

Conclusion:

Where to start with this one... well let me just say that this is a campaign I've been waiting for ever since I played the original version back in 2009. It was and still is one of my all time favorites and I'm happy to say that Suicide Blitz 2 doesn't disappoint in any way, it even goes beyond the greatness of the original! The overall design is brilliant and the amount of details in the maps is simply stunning. You can see a lot of work went into making this, and for me it was definitely worth the wait! What struck me most was that Suicide Blitz 2 stays very true to the original but still provides a completely new experience by adding so much new stuff!  It really felt like the L4D 2 survivors were on the trail of the original survivors but only a couple of weeks later. There's probably too much to list of the things I liked about this one so I'll just say that this is without a doubt one of the greatest custom campaigns I've played and for those who haven't played it yet, be sure to download it and be amazed!

Pros:

Great and interesting design!
Nice voice acting.
Finale was exciting!

Cons:

The bots seem to have some problems navigating around maps.

Conclusion:

All in all a very nice campaign with a very distinctive style and interesting design. I also thought the added voice acting was a nice touch. All the maps were well designed in my opinion and the finale was exciting to say at least. Only downside was that the bots seemed to have some problems every now and then navigating around the maps. Overall great work!

Pros:

Incredible level design (some of the best I've seen so far).
Varied locations with plenty to explore!
Very original panic events!
Great use of weather transitions.
Fantastic challenging scavenge finale!

Cons:

Needs custom voice acting for the finale.
A sound effect for the explosion in the outro would be nice.

Conclusion:

This is without a doubt one of the best L4D campaigns I've played. It totally fits within the story and atmosphere of L4D. The level design is stunning and very detailed. I also liked the fact that there was plenty to explore in each map! I played with bots but they navigated flawlessly throughout the entire campaign. I liked the panic events a lot, they were original and really added something extra to each map. Also great use of weather transitions! Last but certainly not least, a fantastic and challenging scavenge finale! Really awesome work there!

I could not find any real cons, but here are some suggestions that could be added to make it perfect:

- The finale needs some custom voice acting as the pilot voice of Dead Air will just not do. He also mentions a plane which makes it a bit silly. 
- A nice explosion sound effect for the outro would be nice.

That's honestly all I could think of, you did an amazing job here, definitely one of the greatest L4D campaigns I've played. I certainly hope it will not be your last! Keep up the good work! :-)

Pros:

Fantastic Valve-like level design!
Great variety in locations.
Amazing details, really feels like a post-apocalypse Vienna.
Does not suffer from frame rate issues unlike the L4D 1 version.
Nice music and custom Austrian dialog at finale.

Cons:

Intro felt a bit clunky.
Strange transition of light from map 1 safe room to start of map 2.
Train made no sound, ride was completely silent.
Outro was really short, would be nice to see a bit more of the building at the end.

Conclusion:

This remains a great campaign and it looks absolutely gorgeous in L4D 2! The level design is fantastic and feels like Valve could have made it. There is also great variety in locations which makes the whole campaign an absolute blast to play. Everywhere I looked there were amazing details in scenery and it really felt like a post-apocalypse Vienna! Also nice was the fact that this campaign does not suffer from frame rate issues unlike the L4D 1 version. Lastly I enjoyed the nice music and custom Austrian dialog at the finale, it gave it a nice extra touch.

There aren't really any cons besides a few side notes but here they are:

- The intro felt a bit clunky. Perhaps the camera panning could be made a bit more smooth.
- There was a strange transition of light from the map 1 safe room to the start of map 2. When I went in on map 1 it was quite dark and there was a red light glowing, when map 2 started it was much brighter and there was no red light to be seen.
- The train made no sound, the ride was completely silent, which felt a bit weird.
- The outro was really short, it would have been nice to see a bit more of the building at the end.

Besides these, I couldn't find anything that bothered me. This remains a wonderful campaign that made an excellent impression when I first played it and the port to L4D 2 seems flawless. Great work guys, keep up the good work and I'm really looking forward to Vienna Calling 2!

Pros:

Fantastic level design!
New intro.
Undead Center map is a very nice addition.

Cons:

Dead Before Dawn 2 is better.

Conclusion:

A nice new version of an already legendary L4D campaign. The level design is as expected: fantastic! I liked the new intro and it's new more southern feeling, it fits well with L4D 2 style. The new map Undead Center is a great feature and indeed the main highlight of this Director's Cut. Although the original Dead Before Dawn 2 is superior to this version, I liked the look and feel of the new map a lot. The new events were also well made and gave Undead Center that little extra that makes it stand out from other maps.

I salute the Dead Before Dawn team on a another job well done! :-)

Pros:

Fantastic and believable level design!
Great panic events!
Epic Finale!

Cons:

The only con I can think of is not really a con at all, it's just that this is a very brutal campaign to play, especially if you're playing with bots so those who are new to L4D will have a tough time surviving.

Conclusion:

A fantastic campaign with some great and believable level design! It also features some awesome panic events that work great! I was really surprised by the finale, it was truly epic! Perhaps those who are new to L4D will have a hard time with this one as it can be absolutely brutal to play on higher difficulties or with bots.

Pros:

Interesting and original level design.
Smooth navigation.
Alternate routes which add to the exploration.

Cons:

A lot of areas felt too clean and empty.
Some panic events didn't make much sense.
Finale was too easy.

Conclusion:

A interesting campaign with some original level design. I played it on single player with bots and they navigated without any issues. I also saw various alternate routes throughout the campaign which made exploration more fun. I did however feel that a lot of areas were too clean and empty. Seeing as this is supposed to happen after The Parish, it needs to feel like we're several weeks or even months into the infection. Perhaps add more destruction to buildings and detail the streets with litter and bodies too make it look more realistic. There were some panic events I really liked, the ones with the birds later on in the campaign worked well. However some of the earlier panic events had us open a normal door (that didn't make any noise btw) or break through a certain barricade with the use of melee weapons which would then spawn an entire horde. This seemed a bit unrealistic for my taste. Lastly although I enjoyed the finale (the corn field was a nice touch) it did feel too easy. I could easily camp inside the barn on some hay piles where most of the infected, including the tanks had problems reaching me.

Overall I think it was a nice experience and seeing as this is the first beta release, it shows a lot of promise! Keep up the good work and I look forward to the next update!

Pros:

Solid level design. Map 3 was especially well designed!
Original locations and settings.

Cons:

Could not find a single melee weapon on map 1.
There are some missing textures in map 1 (usually crates).
Some very weird level transitions (night to day, just like that?)

Conclusion:

Let me start by saying that this is not my final review/rating of this campaign as I sadly could not finish it. There is a serious bug on map 3 (like some other people have already pointed out) that completely crashes the game. It happens when you go up the wooden stairs in map 3 as can be seen in the third screenshot. I've tried it several times and it keeps crashing every single time.

Now the campaign itself:
The level design is quite solid. Most areas are well made and have a great feel to them. There were however some locations (like the start of map 2) that felt very empty and could definitely use some work. I really liked the variety in locations that you come accross. Sometimes however the transitions from location to location feels very weird. A good example of this would be going from pitch black night in the city at the end of map 2 to bright and sunny daytime in the mountains at the start of map 3. Apart from that I have to say that I especially liked the look and feel of map 3, it was really well designed.

There were some other small things like the fact that I couldn't find a single melee weapon on map 1 and that several textures on map 1 were missing (purple), usually on crates. I also found that the panic events on map 1 and map 2 were too easy. You could easily corner camp in one section while all the infected would come from one side only (this was especially noticeable on the construction yard event on map 2).

I'd really like to play more so I hope you can fix that bug on map 3. It looks like a promising campaign!

Pros:

Coal'd Blood resurrected!
Good level design.
Interesting panic events.
Outdoor exteriors are a nice change.

Cons:

A lot of areas need work.
Campaign feels too long.
Could use more weapon spawns and ammo placement.
Finale is very brutal, perhaps a bit too much.

Conclusion:

I finally got around to play this with a full team of friends and I can say we definitely enjoyed ourselves. It's great to see Coal'd Blood brought back to life! The level design is again great and the author definitely improved a lot of areas and made them more interesting. The outdoor exteriors were especially a nice change. It was also nice to see that you had to work together as a team to overcome certain obstacles (though people who want to play it on single player will have a very hard time). In any case, many of the panic events were very good and added much to the overall campaign.

That said, a lot of areas need work. I understand this is a beta version of course but in many places the map felt bland and unfinished, especially many corridors that looked the same. I also felt that the campaign itself was too long. Most maps were fun to play and well designed but there were certain points in several maps where I felt some of the areas could have either been cut or mixed with other parts to make it more interesting. Me and my friends also had a hard time conserving ammo as most places were littered with infected and we often had hordes coming at us. This might have been easier if there were more weapon spawns and ammo placements. The finale itself was exciting but very brutal. Now it's alright if you really have to work to make it to the end but in this case it was too much. Spawning two tanks can be exciting, but not while there are massive hordes in the area that just keep coming over and over again. Perhaps it's an idea to give the players a breather every now and then to at least give them a chance to heal or grab ammo.

Overall a very good campaign that has lot's of potential. With some polishing here and there this could become something great for sure.

Pros:

Brilliant level design!
Amazing custom scenery and props.
Great and original panic events!
Survivor dialogue.
Bots navigate without problems.

Cons:

Could use a little more info on where to go at times.

Conclusion:

Without a doubt a incredible campaign that has some of the most brilliant level design I've seen so far! The maps are full of details and the author really outdone himself on many areas by adding many additional rooms and paths which supports exploration and makes you keep coming back for more. There were also many original panic events and obstacles which worked great and added a sense of realism to it all. I also noticed the added survivor dialogue which was very well placed. My biggest surprise was that it was very single player friendly. The bots seemed to navigate without any problems, even in areas that you'd think were problematic.

The only tip I would have for the author is to add a little more information on where to go next. I had no problems finding my way in the first two levels but the third and fourth maps could use some more info (especially during the Foundry crescendo).

Overall a fantastic campaign in every way that everyone needs to play!

Pros:

Good level design.
Feels realistic.
Alternate paths support exploration.
Classic and tough finale.

Cons:

Rolling Crescendo on map 4 needs better info on what to do.
There are two planes visible on the outro vid.

Conclusion:

Great campaign! The level design is very good and feels realistic. Awesome port of a classic L4D1 campaign!

Pros:

Very original concept!
Amazing attention to detail.
Great atmosphere throughout the campaign!
Bots navigate well without problems.

Cons:

Though the finale is original, it's not very exciting.
Needs a proper ending sequence.

Conclusion:

Great campaign with a very original concept! There is an amazing attention to detail everywhere you look, this one truly belongs with the big dogs such as I Hate Mountains and Dead Before Dawn. There is also a great atmosphere throughout the campaign which really adds to the story. When playing with bots, they navigate very well without any problems.

If there has to be a low point to this great campaign it's probably the finale. It's quite original in a way but it wasn't really that exciting. Also it definitely needs a proper ending sequence.

Pros:

Great detail, feels like The Passing!
Finally a highway that really looks and feels as a highway!
Realistic architecture and believable abandoned areas.

Cons:

The floodgates crescendo on map 3 needs a bit of tweaking cause it feels too easy.
The Finale, although original, needs a bit of work as it's currently the only map in the whole campaign that is less detailed as the rest.

Conclusion:

Great campaign with a really nice look and feel to it! The most obvious comparison would be The Passing. I really liked the highway, it's the first time in this game it actually feels and looks like a proper highway. The rest of the campaign also features some realistic architecture and believable abandoned areas.

There aren't really any low points but the floodgates crescendo on map 3 needs a bit of tweaking cause it feels too easy. Also the Finale, although original, needs a bit of work as it's currently the only map in the whole campaign that is less detailed as the rest.

Apart from these points, this is a great campaign that should definitely be checked out by everyone!

Pros:

Probably the greatest L4D  campaign so far!
Amazing level design.
Incredible details everywhere you look.
Very well optimized for both campaign and versus.
Finale is challenging!

Cons:

There seems to be a glitch when the helicopter crashes in the second level, though it's quite easy to avoid.

Conclusion:

A amazing achievement in level design and probably the greatest L4D campaign so far! The levels are so detailed that you will be amazed wherever you look. The campaign is also very well optimized for both campaign and versus. Bots don't have any problems navigating the areas and playing as Infected is loads of fun as there are plenty of spots to attack from. Lastly the finale is challenging and adds a fulfilling end to this incredible campaign!

Pros:

Great and original design!
Custom textures and models were all very well done!
Added dialog was a very nice touch.
Nice new tank skin!

Cons:

Aside from the recent update, everything worked well.
The backtracking was nice but really needs more variety.

Conclusion:

When I first played this campaign in single player everything worked fine, later on I downloaded the most recent version and tried to play it with my friends but found out that the safe room door by the elevator was broken, also the pump that needed to be activated at the finale would not start. Aside from that I think this is a very original and well designed campaign. I enjoyed the custom textures and models and the use of added dialog a lot. The new tank skin was a nice surprise too! I thought the gauntlet was a nice touch and made the campaign more challenging. Lastly the backtracking part was nice but really needs more variety apart from the fire, some alternate paths or obstacles would make it even better.

Pros:

Good recreations of the original HL2 maps.

Interesting use of infected spawns.

Cons:

Could use some more detail in certain parts.

Finale should be polished.

Conclusion:

A very nice campaign which definitely takes you back to HL2!
