This was unexpected...

Yeah, yeah, the details are much better than Vienna Calling 1, and there're also many more unique ideas, but I can't really enjoy this... I only liked the design of the second and third maps, while the other maps didn't interest me at all. The overall experience is pretty dull. Nav issues are everywhere as well. But I have to say, even though it's this terrible in my opinion, it's still better than many other campaigns...

Needs to be fixed

There're many more nav issues than I thought... Playing this on Realism Expert with improved bots wasn't such a good idea. However, the design is nice, although the finale seemeds a bit lazy, and it's clearly not Valve style (so it's bland sometimes and can't be very fun for me). The details are nice enough considering this was originally made for L4D1, but it still disappointed me as I though most classic L4D1 campaigns would have been well improved before being ported by the original authors themselves. This is clearly an exception :(

Review

Basic campaign with a few issues. The design can't interest me, but it's not below average and is acceptable. The visual details are so-so and kinda rough overall, mainly because they look monotonous and samey, and there're few objects in each room/area. However, this campaign has no fatal problems, and its desert theme is still unique today. Not bad considering this is beta version, hope you can make it more detailed, interesting and less bugged in future updates :)

不错

趋于轻松的一张小品级地图，设计中规中矩，光照很舒服，就是细节尚显粗糙

质量超高的国产图

流程很长，细节极佳，难度平衡，设计高于平均水准
作为国产图，本图（喜闻乐见地）特意对一些内容做了天朝化工作：中文涂鸦，汉化纹理，甚至有中文配音（虽然有点棒读的感觉，不过综合来看还算加分项），诸如此类。此外，地图的细节程度非常高（使用了许多其它起源引擎游戏的资产，怎么想也不会太差），（听说）还原度也十分到位，可谓诚意满满了

不过确实有些让人不太满意的地方（至少对我来说）：
- 优化一般，虽然这通常是不可避免的
- 路线有点绕，玩起来有点沉闷，相比那些经典老图少了很多趣味性（再次强调是主观感受）
- 空气墙过多，比较影响体验（如果是为了严谨的话，这比某经典复刻图的救援关还要严谨n倍啊……）
- (BUG) 通关后的统计数据无法正常显示（去年12月时就有这个Bug了，貌似现在还存在？虽说我只玩了第一个版本就没再碰了，因为鄙人并不喜欢这图）

总体上还是十分推荐的，应该算得上国产图天花板之一，不知未来是否仍会有能媲美那些经典老图的热度

更新：
2个月后：某服还有40%左右是玩这图的……离谱热度

再更新：
4个月后：现在某服只有20%的人在玩这图了>_<

Perfect (maybe except details) as usual

There's nothing to say. Absolutely recommended.

Review

Honestly, it's less balanced and detailed than the new version. The design is also, of course, worse. I believe that someone just prefers old stuff or hates valve and always tries to find an excuse to post complaint.

The real "DEAD END" (another campaign I forgot to review)

Sadly, its design level is lower compared with Downtown Dine, although its details are much cooler. It has lots of unique stuff, but that also makes the maps look a bit messy and sometimes rough (as the quality of some custom contents still needs to be improved). Still, you can enjoy this.
P.S. One thing notable is that the ending is truly hopeless - the survivors literally hit a dead end.

Pretty but dull

I would give this 3 or fewer stars if there're not such great details. The gameplay is disappointing and the design is boring - looking for something isn't always fun, especially when hordes spawn from time to time. The layout of the areas also can't insterest players. In short, this campaign basically share the same pros and cons with Chernobyl: Chapter One, but that campaign is better in some ways - at least I haven't found a way to skip the finale in that campaign. Yes, if you already lost interest before the finale and want to finish this campaign quickly, you can just try to jump through the barbed wire near the final door.

Something cannot be well described through words (another campaign I forgot to review)

Warning:
This is the most difficult and unbalanced one in the great Questionable Ethics series. It can be RATHER fun on ANY mode, as long as you can complete the challenges. Good luck.

You can skip this... (another campaign I forgot to review)

The details are okay, but the design is below the average.
On the first map, the panic event doesn't work, and you just have to walk for a quite short time, through bland areas...
The second map requires you to walk in a straight line to get some gas cans, then turn back, walk in a straight line again and fill a car with the cans... The stupid (not mean to be this rude) hordes and Tanks will help you.
And that's all. What can I say...

Another campaign I forgot to review

Even though there're more jokes and less annoying/meaningless stuff (compared with The Cure), I still don't want to accept this, as this basically shares the same flaws with The Cure...

Back to Allegheny forest

So, I guess the author listened to someone's criticism (that guy only gave Lockdown DLC 3 stars) and decided to make most areas large, but, ugh, I actually think the sizes of some areas need to be smaller now... As a result, I'm upset to say that the design level is actually lower than before. The pace is still very fast, but in this campaign it remains to be more optimized and balanced, although it succeeded in making players pay less attention to the design (again), and the difficulty is actually lower than Lockdown DLC. Still, the details are amazing and impressive - the author always does well in making nice scenery. In my opnion, the experience of playing this is still like tasting fast food, even though it's delicious.
Oh yeah, if you dunno wtf am I talking about, this campaign may be a bit unorthodox and even cheap in some ways, but it's rather worth a try.

The title said it all (another campaign I forgot to review)

Yeah, you can see the ideas from the previous two Questionable Ethics compaigns in this campaign, and I'm sure it's not the funnest and most prettiest one in the QE series, but that's just a small complaint for a campaign in such a great series. Donwload and enjoy!

Another campaign I forgot to review

It seemed that the level design of GoldenEye 007 wasn't quite suitable for L4D2, but the author used cool visual details and fast but nice pace to attract my attention. I would be glad to play this more than ten times.

One of the funnest (another campaign I forgot to review)

I have played it dozens of times, and have tried it on Death's Door Expert, Realism Expert, Hard Eight Expert... no matter what mode I play, I can find tons of fun in this map. What are you waiting for? Just download it!

Much better than I expected

It has enjoyable details and design, also includes unique and fun events. Although it is also clear that this needs more work (there're nav issues, missing textures, etc.), I strongly believe that this is underrated.

"Flower Vase"

The scenery is great, but it's design... Well, each map is very, very short, and the pace is also quite strange. In addition, there're some nav issues, and survivors can't spawn properly in the fourth map if they died in the previous map. The helicopter in the finale is also, I don't know why, invisible... Play it for beautiful sights, or not.

Just simple (another campaign I forgot to review)

Yeah, it's simple in all aspects but the difficulty, so better not expect for something incredible. Realism Expert is definitely possible anyway.

Review

Puzzles are the soul of Resident Evil campaigns. Dunno why someone want the author to remove them :(  However, this is still nice, although it's not that fun now.

Old treasure (another campaign I forgot to review)

Who can believe that this campaign was first released in 2009? Today, it's still much better than some other campaigns. Quite featured and worth admiring, although the areas are kind of "tiny" (common in old campaigns), which lowered the design level.

Someone blocked me to stop me from writing reviews for some campaigns that wasn't made by him XDDDD
But luckily the real authors of some campaigns are here on GameMaps (L4DMaps).

Great "dining" experience (another campaign I forgot to review)

It's much funner and more enjoyable compared with some so-called "perfect campaigns". But it you're the kind of the player who puts details in the first place for no reason, well, while the details of this campaign are nice enough, but you'd better go to play those "perfect campaigns". Yeah, I mentioned some players on purpose.

Another campaign I forgot to review

Standard gameplay, unsatisfying details. The biggest problem is that most areas are too empty. Hmm maybe it's just another campaign prepared for specific fans of another game.

Review

Still very unique, but compared with MIC II, there's too much troll stuff and the quality is many times lower... Yeah, completely not recommended if you're a beginner.

Avoid this and go to play the original campaigns

This is just a mix of MIC and MIC II, but even worse than the original maps sometimes. Poor troll Huck :(

Rough but classic

There're still some nav issues... anyway they're hard to find and are actually good for players.

How nice this campaign is for you depends on how experienced you are. There're plenty of CI, and SI is also a big matter when you play modes like Hard Eight. I think killing the infected is actually the source of the fun in this campaign, although there're some other advantages - unique theme, creative ideas, several jokes, etc. The design and the details? Forget about them. Just enjoy the cruel pleasure.

It can be improved

Pros:
- Fun
- Pretty lighting
- Few issues
- Unique comic effects and some other interesting stuff (although you may not notice them)
- Balanced

Cons:
- The maps are too small to be a real great campaign
- Samey in some ways
- Cheap finale. The area is too open, and I easily found a place with no nav mesh covered.
- The details of some areas is not quite nice

Conclusion:
Worth a try.

Facts have proven that the newer, the better

I have to reiterate that I'm not who always prefers old stuff, and I played v5 first, and then v3. So... Yeah, it's not as good as v3, and for sure it's far fromthe level of v5. Compared to v3, it's even more undetailed and bland. I'm glad that your mapping skills became better and better as time went by.

Let's play Questionable Ethics instead

Rough (in details), merciless (in difficulty) and bugged (in nav). Never thought that I would spend 4 hours completing this on Realism Expert. However, if you can find enough teammates with you, this actually can be said to be fun.

Review

I'm not who always prefers old stuff, so I want to say that this version is less detailed and more bland and aimless compared with v5. Still a nice campaign to play, but I suggest you try v5 first.

Another campaign I forgot to review

Pretty mediocre. I can't believe that this kind of poor design is from an unfinished official campaign. The previous 2 maps are about troll and confusing stuff, while the finale is boring and repetitive.

Review

It seemed that you were good at making creative campaigns, but in my opinion you didn't make them real fun :\
The design is as mediocre as you can guess, and I can't review the other aspects in a objective way. Yeah, this campaign is just for those who want to try something new.

Another campaign I forgot to review

Although it's rough in details, it's unique in design. A nice fact is that the more times you play this campaign, the easier it'll be for you. However, it's always a bad idea to play with bots :P
Btw, there're 3 Zoeys in this campaign?? One died in the prison (and you can only see her when using noclip), one is still alive in the prison, and the remaining one is the car driver in the finale. That's confusing...

Great

Nice campaign with unique design and pretty details, but the cave part of the second map is a bit bland. I wish I could spend less time walking in the cave, although it's a quite creative idea to follow the fireflies. Other than that, this campaign is fun to play.

Nice

The layout and the details are simple, but plays fun. Yeah, you need to take care in the finale if you play on Single Mode, as there're 10 colas waiting for you to collect. Don't worry, it's actually possible to complete it on Single Mode Realism Expert (and it's not quite difficult), but you'd better install Left 4 Bots. That's all, I guess.

I believe that this is just a mapping try

Finished in about 10 minutes on Realism Expert... Quite short, easy and disappointing, although the details are nice considering it's your first campaign. Not recommended as the design level is horrible.

Nice

It has many areas for exploring as well as many creative and fun ideas, and the details are nice. However, there're many issues. Most of the issues are about nav mesh, while one is about the glow of the cola - it doesn't exist, so I'm unable to find the fourth cola even if I explored the whole map 3 times :/

Creative

Nice rat campaign with many unique ideas, although walking across large areas may be not fun sometimes.

Review

Not bad, tends to be open and has some unique ideas. The details are rich and the visuals are rich, but some areas are too similar. Also not that challenging (I think I have the right to say that as I finished this on Realism Expert), and if you're careful enough, you can find a sopt that isn't covered with nav mesh in the finale.

Well made

Well balanced. Although it doesn't has an impressive color theme, it made me think it could be another The Passing. However, the gameplay is a bit bland, and for that I played this on Realism Expert, I have to say that there's too little ammo in the finale.

Mediocre

To be honest, it's quite disappointing. The author tried to make this not so ordinary, but as for me, he failed. Overall it and has uninteresting design, due to too open, repetitive and unpolished areas, and it's also not well-detailed. I kept hoping to see something real exciting when I played this, as this campaign has 1.7M views on this site, but my hope were completely dushed when I easily found a place with no nav (which means the infected can't harm you when you're in it) in the finale. How awful...

OK...

Very short, only needs you to walk through a whole train. That's a creative idea... But that's all. Quite boring.

Bugged

The design is worth admiring, although it's obviously inspired by official L4D1 campaigns, but it doesn't play bad. Details are not good, but I guess they're OK as for a L4D1 campaign. But yeah... this is bugged and needs to be polished. The main issues are that I can see CI spawn in my field of view and there's too few invisible walls.

Dark Carnival Ultimate Edition

An upgraded version of the classic official map, almost perfect in all aspects, showing the great talent of community mappers.

Deadly ideas (another campaign I forgot to review)

There're many random paths and events in this campaign, which greatly improved the gameplay, but might also make the experience depressing sometimes. Besides, the details and design are nice, although they're not much above average, they have their own shining points. Recommended for experienced players.

Review

The details are kinda repetitive but nice. The design isn't very decent, just some classic narrow area tricks, but there's everthing that should be there. Btw I suppose the author intentionally put some troll stuff into this campaign.

The track is polluted... (another campaign I forgot to review)

The details are enjoyable, but the design isn't. Most of the time you're just walking in wide and open areas, with some rolling terrain and sporadic buildings. Yeah that's not very fun. What a pity, because it's clear that it could have been a real great campaign.

Review

Not a great campaign for me. The details are not quite enjoyable from start to finish, though the lighting is okay. About the design, I agree with holybased123 - the design of the first 3 maps is pretty mediocre, while the last 3 maps are above average. Overall, the maps are of varying quality, making this campaign not very attracting, at least for someone.

Review

Not very pretty, but there's no point in focusing on most aspects. I guess the biggest gimmick of this campaign is its difficulty.

Our hope isn't buried (another campaign I forgot to review)

Hard but balanced, not decent in visual but in experience, using common content but being unique. The only problem, also a common problem with most long campaigns, is that it may be kind of bland when there's no events. Highly recommended.

Not fatal, but fun (another campaign I forgot to review)

Great campaign. The wonderful design is absolutely on par with Valve campaigns, but at the same time most areas are repetitive in visual. However, fun is the most important thing. I really had a joyful time, so I appreciate this.

Another campaign I forgot to review

Pretty hollow, both in design and details. Also not very fun. Maybe that's just what basements should be.

Pretty look (another campaign I forgot to review)

A long and pretty campaign. Every map has its own special theme, which makes this campaign extremly impressive. But the design and gameplay gives me a hollow feeling, especially the fourth map (I know most parts of that map was taken from HL2). Still worth admiring though.

Another campaign I forgot to review

Nothing's really impressive except the overall color of the scenery. Kinda basic, even the design doesn't have its shining point. Still enjoyable and worth trying though.

Another campaign I forgot to review

The processing of the maps is relatively rough, the author didn't really make the gameplay suitable for L4D2. However, overall it worth a try, especially for HL2 fans.

Old treasure (another campaign I forgot to review)

The best example of porting maps, truly made the gameplay impressive and fun. A incredible gift for HL2 fans.

Review

没什么让人印象深刻的地方，也没有中国城市的感觉，流程设计水平不足，场景设计比较雷同，风景细节中规中矩，是趋向于平庸的图

Review

Fv5.1版的增城，地图设计不太给力，糟粕大多，事件安排不到位，大约70%的时间都十分无聊，让我第一次体会到打L4D2打累了是什么感受
不过场景在这个版本已经是有模有样了，为此可以加2分

Review

考古了下老板，感觉还是新版好。老版犯了长地图的通病，而且呈现效果比较让人失望，新版的设计就更缜密一点，流程调整得十分不错，可玩性大大加强。总体而言，新版是一张非常优秀且有趣的还原向地图。

Review

很不错的HL2移植图，在L4D2的呈现效果非常好，玩起来也十分有趣，比较值得多次游玩（已经玩了不下20次了hiahia）。不过救援关的大片空旷区域的确有点无聊的说，作者对地图的修改还是过于拘谨了点。

Review

该图也算是我入坑玩的第一批三方图之一了，“情怀”挡在这，不太好打分。
尝试分析下优缺点：虽然缺乏细节，但画面整体色调做得很不错。设计还行，不能说出色，但值得欣赏，一些事件的设计也挺有创意的，可玩性也十分不错。不过既然是虚构城市，前二关还不是中国城市，就应该能自由发挥一点，但最终成品还是缺少地形变化，V社官方介绍的12个设计术语在本图当中并没有体现很多，依然有所欠缺。

Epic journey (another campaign I forgot to review)

It's one of the best campaigns that restore real life places. The atmosphere is great and makes players feel like they're in a real apocalypse. The details are quite great, you can know that from the screenshots. The design of the second map could be improved, but the designs of the other maps are quite nice. It definitely has a chance to become one of the top 5 addon campaigns.

Another campaign I forgot to review

Overall it's a great campaign with high quality. The details are nice and the overall layout idea is creative. But many areas are too open, and the details and design of different parts of each map gives me a samey feeling. What's more, the second map is not well made. Other than that, there're not many shortcomings.

Great

Obviously carefully made. Both details and design are pleasing, but holdout events aren't set well, the walkable parts of most areas tend to be narrow, although many campaigns have such problems.

还是欠缺了一些

游戏体验明显说不上让人失望透顶，但绝对差强人意。场景多数都较为空旷，走起来有点无趣，路线设计也算不上有质量，不过好在事件的设置比较到位，避免了长时间的枯燥乏味，只是可惜事件（尤其是M2的事件）本身的安排也低于预期。场景塑造也属于不好不坏，使用自定义资产的区域看起来还不错，只使用官方资产的区域就有种L4D1标准三方图的感觉，多数区域还因过于空旷且缺乏细节而拉低了观感。总体而言并不是十分平庸的图，但离优秀地图还有很大差距。

Another campaign I forgot to review

Standard rough L4D1 campaign. Don't expect for great design, satisfying details, few issues or anything else. Not worth playing.

Another campaign I forgot to review

The fifth map is quite boring and difficult, other than that it's a standard fun Glubtastic campaign. We can see that the quality is getting better and better.

This campaign has more Tanks compared to other Glubtastic maps, which makes it the most difficult one. That's the only thing I want to complain. Other than that, it's still a fun and unique troll campaign with many hidden tricks. Btw, expert is actually possible, and once I even completed the second map on Hard Eight Expert, mainly because I know many tricks.

blank

Another campaign I forgot to review

Warning: as you can guess, this is a troll campaigns.

This campaign perfectly describes that fun is the core of an addon map. The gameplay is fairly unique and unorthodox, and the author truly made it interesting. There're many tricks, the more times you play this campaign, the more tricks you find. Even though this is a troll campaign after all, I find it funner and funner as time goes by.

Relaxing (another campaign I forgot to review)

Another campaign that restores real life places, but much more enjoyable than some other campaigns. Everyone can see that the author put much effort into this, and he made the difficulty very low in order to make sure all players can enjoy the scenery. But at the same time, the low difficulty can also be a shortcoming, as it makes the experience kind of boring sometimes, although that doesn't matter anyway. Fun is more important than details, design or anything else, even though issues can break it. Waiiiiiit, I don't mean this campaign have many issues!

Ended before daybreak (another campaign I forgot to review)

Great campaign overall. The details are nice, however, they can be better in fact, and I believe that some brighter and warmer color corrections can greatly improve the look of the sights. The design isn't quite decent, but above average, although I can feel that as the game progresses, the design level becomes lower and lower.

Don't lock up your talent (Another campaign I forgot to review)

It's a nice fast-paced campaign with surprising details, although the design is... unique, I guess. But hey, this is not a campaign that only has narrow areas, so I'm not gonna put unpleasant criticism here. In my opnion, the fast pace actually makes players pay less attention in the design and lets (some of) them feel like they're tasting fast food, you know what I mean. I'm not gonna like this as I prefer Valve-like designs, but this is actually very worth a try.

Review

I prefer the Enhanced version in some ways, mainly because it has fewer issues and higher difficulty, key searching tasks also actually encourage me to explore more instead of just running to the saferoom.
Reposting my review for the Enhanced version: 80% of the time it's a bit bland, but overall it's great. Amazing details and atomsphere. Silent Hill OST also makes this campaign praisable. Recommended for experienced players - although it's not difficult at all, but I'm afraid that the surprising length will drive beginners crazy.

Giving missing reviews...

Although it's not one of the top 5 addons campaigns in my mind, it is still the best campaign that has a facility theme. You can't expect for amazing design, but the details, eastereggs and so on will satisfy you, although sometimes it's kind of samey. One of the must-play campaigns.

Time to review

It may be one of the campaigns with almost no shortcomings. Gameplay, details, designing... Everything is perfect for me. Still a powerful competitor for the place of No.1 addon campaign.

Leave my footprint here

One of the best addon campaigns, with a real perfect zombie apocalypse atmosphere. It's even better than Valve campaigns in many aspects (but not in map designing, yeah).

Great

Quite solid, although the pace doesn't exist and it's a bit easy. The puzzles are intesresting to solve, mainly because they're not difficult (at least 1 hundred times easier than the puzzles in Kink) and don't always require you to find something. Highly recommended for those who don't hate puzzles, even for non-fans like me.

Review

Looks like I forgot to review this. An short and easy campaign, with average design and details, which would be a nice choice to relax after playing a long or hard campaign. There does be some issues, as an classic example, I can easily get to the top of the invisible wall in the finale, so that the infected (except Smokers) can do nothing to me.

Review

Haven't played any Silent Hill games yet, so the special theme means no thing to me. Not bad, although the design and details are kind of rough, but I can feel that you put much effort into this.

Review

I know it's a puzzle campaign, but it's way too long and boring... 90% of the time it's bland, even though I played on Expert. There're no amazing details to satisfy me, the design is also disappointing, and some issues (for example, on the 12th map, bots will fall from the ladder) still exist at the same time. I'm not a Silent Hill fan, and I've played Silent Hill: Otherside of Life before this, so, sorry, but I dislike this.

No

The details and atmosphere can give you a unique feeling, but that can't save this campaign. Bugs come the first. No one can sacrifice like Gandolf in the first map, players have to cheat or use an idle trick. Terrifying elements come the second. Falling rocks when climbing the Mount Doom and continuously spawned charger at the Cracks of Doom are best examples. Horrible balance comes the last. You have to kill tons of Tanks in the final map, and completing the map takes one century. The three shortcomings ruined this campaign. I suggest you play this on a modded server for best experience.

Review

I remember this was one of the first addon campaigns I played. Maybe I tried this just after Left 4 Mario, so I was surprised at the details and length. Looking at this from today's perspective, although the design can be said to be nice, it actually feels hollow, both in scenery and gameplay. Maybe that's mainly because of the original author's mediocre ability in areas creating. Still a good campaign overall, considering it was originally made for L4D1.
And yeah, no one liked the trolling actions taken by the original author.

Epic

70% of the time it's a bit bland, and key searching can take 5~30 minutes, but overall it's great. Amazing details and atomsphere. Silent Hill OST also makes this campaign praisable. Recommended for experienced players - although it's not difficult at all, but I'm afraid that the surprising length will drive beginners crazy.

Review

I believe that this campaign is for nostalgia, so don't expect too much from it. Not recommended for those who haven't played the original maps in CS 1.6.
Details: The original maps are from CS 1.6, so...
Design: Simple, with a scavenge finale, so you'd better not play this with bots.
Gameplay: Medium. Fast pace makes up for this shortcoming.
Fun: Neither much nor little.

OK

Nice easy campaign, with unique scenery and feeling, but the design is too simple, although I can't say it's terrible. Enjoyable overall.

No politics

Map quality score: 8.1/10. The author showed his nice mapping ability.
+ Politics = no score

Like all other campaigns made for the China contest, this campaign didn't show anything real or objective. But in addition, it was also filled with prejudice and slander against China, which made the matter a hundred times more serious.
If you want to see what Chinese cities actually look like, play Nanning or Zengcheng Guangdong instead. If you insist on being intoxicated by vanity and lies, no one can stop you from playing this.

Not bad

Basically a nice campaign. The author wasn't experienced for map designing, but he put creative ideas in his maps and tried to make them fun. Although the final result is still not pleasing, it's much better compared to your previous campaign.

Review

Quite simple, but enjoyable. It has everything a standard campaign needs, but I still don't recommend this to non-fans, unless you want to play this on high difficulty (insert file "noob practicing realism expert.jpg").

Great

The details aren't quite pleasing, the pace of the first and fifth map is weird, and the bot nav is broken sometimes. Other than that, it's a great campaign. To be honest, it plays much funner than some other campaigns.

Nice

The author showed lots of unique ideas, but he forgot to make this campaign REAL fun. Yeah, nothing's disappointing except the design - it can vquite boring to just walk for long periods of time.

Review

I guess pretty doesn't mean "fun" most of the time.
Pleasing but repetitive in visual, a little above average in design, disappointing in difficulty. Maybe it need some areas that are not very narrow. Lazy finale btw.
Another overrated old campaign in my mind.

Epic

This review is based on version 1.05. Get it from ModDB or Steam Workshop
Finished in 1 hour 15 minutes, restarted 3 times, on Single Player Realism Expert, with an old version of Left 4 Bots 2 enabled.
It has the most incredible details I've ever seen in L4D2, but the gameplay, well, is not that great. If you know the right path well, then the only thing you need to worry about is the CI. The number of them are horrible! Tanks are also common, but not that depressing, because the map design makes it not very difficult to fight with them. Talking about the design, well... I have to say the only fun is to kill zombies. Maybe the author just wants you to enjoy the sights.
Overall it's an epic campaigns, but the author left too many issues unsolved in this campaign... Tanks can get stuck somewhere on the fourth map, CI would spawn in places you've already explored, and you can easily receive a "no free edicts" error when the game is changing level to the fourth map... Due to these issues, it's not a perfect campaign in my mind. Sorry, but just 9/10.

Review

Finished on Expert within an hour. Basically you can think of it as an extended version of White Forest, with a different atmosphere and some changes worth noting. Most changes just increase your play time or reduce your fps, which isn't worth talking about, but the changes to the second map reduce the difficulty greatly... That's not good. Overall, the changes to the previous four maps can't bring you much more fun, but they're acceptable. Then let's talk about the two new maps. To be honest, I don't like them. The fifth map is way too short and easy, and the event is just boring because there're only 5 gas to collect and the hordes are completely not a problem. The sixth map is quite large, and it requires you to run around, touch this, touch that, kick tanks' asses, run back and press a lot of buttons. Yeah, that's not fun for me, because I never liked to run through very large areas or to do repetitive tasks in L4D2. What's more, the fps was only about 30~40 for me, which makes the experience even more unpleasant. I give it 4 stars, for it is a HL2 campaign and nothing more.
And there's another problem: the author of White Forest is Missed, not mixmedia, I think.

Nice

Fun campaign, especially when playing on Expert, although it doesn't have many shining points.
+ Creative ideas, such as unlockable doors (kinda meaningless though)
~ Basic design
~ OK details
-- Bot nav issues
I'm gonna try Beldurra 2 next, and I hope it will bring me more joy.

Not bad

This is a relaxing campaign with some unique ideas. The design is just so-so, but other stuff like environmental sounds and simple but nice scenery caught my heart. Oh, yeah, issues are easy to find, especially in the finale.

Review

Not bad campaign, with nice design and balance, which makes it suitable for Versus. However, that's all - it's just basic in most aspects. Also, most walkable parts of the areas are kind of narrow, and the design of the finale is lazy.

Is orange theme an excuse for poor quality?

I've played two great orange-themed campaigns (The Orange and Oranssi Paska) that are many times better than this, so, sorry, but I can't accept this. Extremly lazy design, unbelievably large and repetitive areas, unpleasant details (compared with other orange campaigns, of course)... Just avoid this.

Nice

It has great potential. The design is pretty unique and nice, but some areas are way too empty, open and undetailed. The finale is also confusing - I spent over 10 minutes looking for the switch.

Great

Another amazing classic campaign with decent details. However, the last 3 maps gave me a dull experience, because sometimes it would be hard for me to find the correct way (especially on the third map), and most of the time the author just let players walk through areas that have very similar layout (it's rude to use "repetitive", right?). That actually doesn't matter if you don't think about other aspects, but hey, the lenght of each map isn't short, so the bad feeling can last for a long time... As a result, this campaign has less fun than other classic campaigns. If you don't care about the defect, it's worth giving it a try.

Classic

A great campaign from the old times. The author has few unique ideas on map designing, as a result the final result isn't very perfect for me, because there're nothing really impressive, attracting or unique, and some areas are meaninglessly empty (that makes this campaign much easier than I expected), the medium-average details also make them look even worse. So, don't expect an epic experience like that you can get from campaigns like Suicide Blitz 2. Other than that there's not many issues. Everyone can feel that the author put much effort into this campaign.

Review

Actually the design is a little poor, but who would care about the design instead of the scenery while playing this campaign? Highly recommended for Minecraft fans, although the crashing issue on the fourth map is really annoying.

Edit: I simply suppressed some textures (with actually no quaility loss, heh) and the file reduced over 500mb, man wtf

Review

A great city-themed campaign, with some open areas for exploring. The design is quite decent, but the details are kind of rough, and some issues actually exist. Also, sometimes it does make players confused (about where to go).

Review

Time to give a review to this classic. This is almost the best campaign that didn't use any custom content, although it seems to be unfinished (the finale is confusing, and at the same time, DarthDed said he would publish a new version soon, but he didn't). It also has some nav and invisible issues, and sometimes it would be kind of bland. Quite worth playing anyway.

Disposable

Yeah, someone wanted to make a campaign that provides players with a ride, and he succeeded. Completely not worth trying if you dislike rides.

Disposable

Pretty ncie campaign, although I haven't watched any Indiana Joines movies. However, it's way too short and easy, even on Realism Expert. Maybe it's for the fans or those who want to see rides in L4D2.

Review

The details are fairly pleansant, but the design isn't. Most areas are too open and monotonous (not visually, of course), which won't bring you fun if dealing with the infected isn't a problem for you. Yeah, I mean this campaign is way too easy and bland. The events are really... well I'm running out of words. Anyway, all the events are alarm events that require you to rush for some time, and some of them are even skippable (for what??). The length of each map is also a little short. I prefer longer campaigns. In a word, it's just that kind of walking simulator, just admire the scenery. By the way, it seems that the campaign isn't very rigorous.

Review

Pros:
- Each map has its own theme
- Nice details
- Few issues
- Okay optimization

Cons:
- Too many empty or repetitive areas
- Way too easy to find shortcuts
- Quite easy finale compared with many other campaigns
- Few melee weapons (why?)

Conclusion:
A classic old campaign, but its difficulty is much lower than other great campaigns.

Nice

Decent campaign overall. However:
- The details are a bit too rough. That actually doesn't matter, but why is the optimization so unpleasant at the same time?
- It's a bit bland when there's no event
- Dunno why bots stopped following me after walking for a while on the fourth map
Other than that, this is a good choice for those who like long campaigns.

Mediocre

A standard fast-paced L4D1 style campaign with low difficulty and lots of issues. It does have something unique, but performs poorly. Everything is so-so, even a little disappointing. Not recommended.

So-so

I don't like these fast-paced L4D1 style campaigns. The details aren't pleasant enough for me. The design is unique and okay, but the finale is way too easy, and if everyone dies on the final map, survivors will spawn in a dark area and be unable to get out. The final map also has even worse details compared with the previous two maps.

Confusing

- The maps (except the second map, maybe) are so large and open that you can easily lost the way
- The details are also impressive, although I don't like the color
- The author didn't go to great lengths to prevent you from finding shortcuts
- The pace is weird sometimes
Recommended for those who prefer unorthodox gameplay.

Classic

A classic orange-themed campaign, including 4 well-designed maps. However, some small issues do exist.

优质的国产官图风地图

设计十分不错，场景做得也挺用心的，选择系统也很有创意感，最后的开车部分放眼全部三方图也没几个能做得这么好，但是实游玩玩的时候很明显能感受到作者想要提高地图的难度，因而塞了不少机关事件，小丧尸生成数量也被刻意增多，Tank的生成亦有别出心裁的调整/设置（有一说一，我没感受到Tank的固定生成和随机生成有什么具体差异，可能是我玩得少了点吧），却怎么也掩盖不了关卡设计难以支持难度变高的事实，故而有一种“被喂饱”的奇怪感觉，这也是我对本图唯一不满的地方。总体上还是十分推荐的（毕竟是难得的官图风好图）。

尚可

同起源引擎游戏E.Y.E.:Divine Cybermancy的移植图，宏大的场景叫人震撼，十二关的总关数也让人惊异，但遗憾的是本图的可玩性十分薄弱，总计约3小时的流程内基本都在找路、找钥匙（这时宏大的场景反而成了弊端），全程很少有让玩家停下脚步的地方（坐电梯不算），指引更是一言难尽，若不是有奇异的风景吸引眼球的话很容易就会让人感到无聊。除此之外，本图的一些细节处理做得比较差（这也是国产移植图通病了），bug（尤其是人机导航bug）也不少，让游戏体验大打折扣。如果不是冲着风景来的话，并不是很推荐玩本图。

Perfect

It's still one of the best training maps for L4D2. I guess I have to play L4D2 a few thousand more hours before I can complete all the courses in it.

Nice

I have to say the maps are well designed. However, some areas are too open and looked monotonous, and the detials isn't very satisfying. Although you can see assets from different games, they are not used very well, especially the assets from INFRA (I even thought an area in the fourth map is dircetly cut from INFRA). Issues are easy to find, like missing textures on the first map. Other than that, it's a nice campaign to play.

I wonder why the author disabled reviews and took Pesaro 3 down from the workshop...

Solid short campaign

Finished in 16 minutes in Single Player mode on Expert. Although it's not quite pleasant in some ascepts, it's decent overall and there're not too much to complain. However, I think it's better to let Tanks spawn in the finale.

Don't try to port CS maps this way

The campaign has three edited CS maps that are full of bugs, and that's all. Each map is as short as you think, which makes them boring to play. Why not just turn them into survival maps?

I want real puzzles, not mazes

This campaign made me think it's full of Portal-like puzzles, but I found out that was a stupid thought after I played it. There's no interesting puzzle, just repetitive mazes. In each room, you need to explore a maze, find an object, put it on a red buttom and do what the campaign asks you to do, then congratulations! The door is open and you can leave the room. Yeah, the layout of the three maps is extremely similar, and all of them are not really fun to play. The finale is lazy as well - the author didn't even create a actual new area for it! Not recommended.

An okay campaign

Pros:
- Nice design
- Okay length

Cons:
- So-so details in some areas
- Weird pace of the first map
- Nav issues

Conclusion:
Not so mediocre, but also not decent. Not recommended.

Classic

Decent design, but most areas look very samey and the assets aren't attracting at all. The final map don't have such problems.

没什么亮点

太短而又太简单，各方面都挺中规中矩的，没有什么比较吸引人的地方，不是为了专门体验海啸城市系列分支走向的话不怎么推荐，倒是挺适合萌新练练手

Playable

Just tried this old campaign. Hmm, I think it's just so-so.

Pros:
- Not too short
- Almost no nav issue
- So-so design
- Nice lighting

Cons:
- Confusing design in some areas
- Too many empty areas
- Poor details
- Mediocre optimization
- Too easy

Conclusion:
Not very worth playing, cuz there're many better campaigns on this website. If you want to try this anyway, I recommend playing on Realism Expert or Hard Eight Expert.

坑味未免太浓了点

设计还行，场景不错，细节较糙，nav糟糕，存在bug，有创意但没做好，部分关卡有其它三方图的影子……只从这些方面来看的话，本图是个仍需调整的中规中矩的图（至少不是坑图）
但当然还有一个不可忽视的方面：感染者生成
首先本图的witch生成得很频繁，在女宿舍那关甚至直接在一个狭小空间内放了一堆witch，虽然作者贴心地给了高爆弹但还是十分恶心
而后，尸潮貌似也有点问题，小丧尸一刷就是一堆，被boomer喷到的话小丧尸可能会一口气刷一堆，然后就不刷了……另外，介于本图设计缘故，尸潮基本没有多大威胁，速砍就完事了
特感倒没多大问题，就是经常会被卡住
最后是tank的问题。简单点说就是随机刷克过于烦人，救援关的克刷得有点多了（我玩的时候一共刷了7只左右），而且刷克时小丧尸不停刷，挺搞人心态的。由于tank生成频繁，这图带痴呆人机玩的难度远大于和别人组队玩的难度（所以如果你和我一样是个菜比就不要想不开地去带人机过专家了）
顺带一提，如果你运气和我一样不好，那么游戏就可能在救援关冲刺事件刚开始时就送你一只tank挡道（当然还会刷尸潮）……而且冲刺给的时间稍微拖沓一点都有可能不够，甚至让我怀疑是不是计时出bug了
总体来说调整下tank和witch的生成，再修下bug、完善下细节，不失为一个不错的图

这里原本放了一堆关于tank生成问题的废话，被我删了，主要是太傻x了

Review

A relaxing campaign to play, with awesome details and few issues. The design is decent, though it's not the best. Now I'm looking forward to seeing mappers port more maps from HL2 mods.

Not so perfect, but OK

This is a campaign with amazing details. You can truly explore the areas, think about the things and infer a story, which can make you excitied. But don't forget that L4D2 is a fps game. I have to say, the design isn't so pleasant, because there're too many large areas for you to wak through in a straight line, and if you just want to run and shoot, then you may feel bland sometimes (if you don't choose play hard modes like Hard Eight and Realism).Overall, it may not be fun enough, but it must be a nice campaign to try.

Review

Not so impressive, but the design is decent. Worth playing for beginners (if they don't care about the details).

-

If you see this campaign and want to try it, please choose to play The Grave Outdoors instead. You'll know why if you check the description of that campaign.

It's getting better

This campaign has fewer issues now, but that doesn't mean there aren't serious issues anymore, although you may not find them if you don't want check every place you can reach.
Whatever, this is another above-average campaign from the author of Left Behind. Well worth playing for those who like long campaigns.

Your best campaign

Respect.
Awesoem details, few issues, decent design, pleasant optimization... These are all a great campaign needs, and your last campaign has all of them. The only problem is that it may be bland sometimes, especially the finale. The poor layout of the final map can make you feel boring (and it's even annoying if you can't find the proper way to deal with the Tanks).

Review

Nice short campaign, with decent design and nearly no issue, but repetitive and boring assets make it not so attracting.

Perfect

Another great campaign from the author of Welcome to Hell. The only two issue are that the skybox may not display properly and game stats don't work.

Amazing

Much better than I expected. One of the best campaigns that mainly use L4D1 assets, with great design, and optimization... It's a little hard for me and 3 dumb bos to deal with the tanks in the finale (on Expert), but luckily the boxes you added to the map helped me in a strange way, lol. I do dislike the weird pace of the first map and the same situation as your sixth screenshot shows, and this campaign has the same shortcomings as most L4D1 campaigns. Highly recommended for those who like L4D1 style campaigns and don't really care about custom assets.

Nice

Medium-average campaign with horror atmosphere (even though it's not scary at all XD). The design is a bit lazy - the second and third maps have extremly similar layout. Also, you can get lost easily on the second map because... Gosh, who can see the "ladder" in such a dark area?

Yeah, it's better than the original one

It's not a completely new campaign, but of course it has something new and nice. The map design and details are better than the original one, but the amount of issues aren't less. Not really a quite nice campaign, but very worth playing if you've played the original one or other SpeedBoost campaigns (except Whispers of Winter).

Impressive, but there're too many issues...

Map design is really nice, even though sometimes you may lose yor way. You may find hordes and tanks brutal, but that makes the game experience fun instead of depressing. Details are okay, but I don't understand why the file is so large... I actually don't like the custom weapon models and textures, so I deleted them myself, and the file reduced by about 200 mb... 
I don't really want to walk about the actual issues, because, gosh, there're too many... You can't avoid them by just disabling other mods, that's the most annoying thing. But yeah, this campaign is still recommended if you want to try something new.

It's OK

It's a relaxing campaign with two endings, but the design and details aren't quite pleasant, as the final campaign of the SpeedBoost series. The random tanks are still annoying, of course.

So I still don't understand what's the connection between these chapters in the SpeedBoost series...

Pleasant

Quite nice map design and details with few issues. The difficulty isn't high overall, but random tanks in the first two maps would be hard to deal with. The only serious issue is that sometimes the finale can't start properly. In a word, it's a great campaign for relaxing.

Ugh...

The first map is really incredible, it must be the best map in the first 4 chapters...
But the second map is much worse. It has terrible optimization and quite low difficulty, and for sure it can take you a long time to find the helicopter.
If you aren't going to try the whole SpeedBoost series, it's not such a nice idea to play this campaign.

OK, I think Frozen: Chapter 2 is better...

Sadly I have to say this campaign is much more mediocre and confusing than the previous one... Maybe it's mainly because this one doen't have a special theme. So we got disappointing map design and details again, the author also gave us annoying issues as extra gifts. What's worse, there's troll stuff into this campaign. Fake saferoom with a tank? Hell no. Not recommended overall.

Not bad campaign

Much better than Beginning Hours: Chapter 1. Map design isn't too mediocre overall, though the finale is still confusing and disappointing. It's a nice choice if you like winter-themed campaigns.

Nothing impressive

This campaign is mediocre in almost all ways... The length is surprisingly short (it took me 15 minutes to complete all 3 maps), both the map details and design are also disappointing. Issues are easy to find as well. The first map is a little confusing because nothing tells you that you'll have to wait for a helicopter (and the helicopter didn't apper at all on the second map, hmm). The second map made my think of the third map of Pit Stop because they have a very similar layout, dunno if the layout is a public asset or something. The third map is just a cheap version of the final map of Blood Harvest. I can't say this campaign has anything impressive, so I don't recommend you to play it. That's all.

Awesome

Higher difficulty and extra areas make the campaign even more fun. For sure, this alternative version has more issues compared with the original version (and most of them can help you complete the campaign more easily). Nice work anyway.

Well...

Pros:
- Nice details
- Few issues

Cons:
- Empty areas
- Lazy design (although it's not very boring)
- Confusing ending

I have to say I didn't see any shining points of it, and as a result, I don't even know what should be put into my review... OK, at least the map is playable.

One of my favourite campaigns

+ Perfect design
 + Nice detail
 + Challenging
 + Few annpying issues (if any... at least I haven't met one)
 + Satisfying length

Absolutely another underrated campaign... Love it.

The last time I played this campaign was serveral years ago. Now I decide to leave this review just because, well, I don't think this campaign should have a rating of only 8.

Great

Hidden treasure for me. The 5 maps are designed really well, while there're some nav issues. (Don't be so worried about that because I don't mean bots can get stuck or something else) 
If you can accept unfeatured campaigns, try it.

Excellent!

Okay design with cool ideas... That's right!
But there're actually more issues than I thought. It's clearly that it needs more love, but it's impossible for a campaign that released 13 years ago to get updates from the author. (So I think it's meaningless to point the issues out)
The only thing I really have to complain about is the finale... There're 4 tanks in total, and you also have to deal with the hordes while fighting against tanks... What a shame.

Uhh...

I don't know what did Huck do, but this campaign is clearly kinda broken. On Map 2 and 3, hordes are never going to stop... The optimization is also disappointing. 
Let's have a look at the map design. Well, it's really not that bad, the only problem is that the maps are a bit short, especially Map 1.
I don't really want to think about the map detail. You just have to know that there's nothing attracting... 
Also, upset to see that the rescue boat didn't move at all in the outro.

Nice

Hmm, it's a good choice if you are interested in playing maps on Hard Eight. You can see water everywhere, and all 5 maps are huge as well, which make this campaign challenging on Hard Eight :P
Yeah, honestly it's kind of bland because there're not too many events.
What's more, there're ping issues on Map 2 and Map 3. Though I was the lobby leader and chosed "Local Server", the ping was about 95ms on these two maps.

One of the best troll maps ever made

It's quite difficult for those who play this campaign for the very first time, but the difficulty actually depends on who many tricks do you know. If you can use the tricks really well, then you can even complete this campaign on Realism Expert, and that's why I love this campaign. Highly recommended for its creative ideas and incredible cutscenes.
Yeah, if you're who can't even complete an official campaign on Advanced, just avoid this, or you may fall mad.

Review

A short but okay campain, the only problem is that the optimization is kind of terrible (considering it's restoring a map from another game). Also, if you're not a fan of RTCW, there's not much point in playing this. That's all I can say, because I don't even know what RTCW is.

Great

Pros:
- Awesome design
- Satisfying detail
- Cutscenes!
- The idea of neurotoxin is quite creative

Cons:
- Bots can get killed by the neurotoxin easily in the finale
- An nav issue on map 2 made bots stop following me. Luckily I have Left 4 Bots installed.
- Floating medkits on map 2 (check the screenshot)
- CI incapacitated me during the cutscenes in the finale (all bots had been dead, so the game restarted)

还算凑合

m1~3貌似是原创设计，设计得还行，虽然用了INFRA的资产但场景细节还是有点贫弱。m4和m5应该是从INFRA移植来的，视觉效果堪称起源巅峰，但做成战役地图的话就在设计方面有些不给力

2024/3/15：噗，推了下INFRA的流程，发现m3不是原创

m1：感染者在已走过的地方生成
m4：有人机生成在地图外；要拿钥匙开的门如果没拿钥匙也能开，只是不能进；钥匙特难找
全部关卡：空气墙太明显了；有些地方还是有材质丢失（可能是我的问题，我是从度盘下的材质）
其余：intro损坏（可能是我的问题）

图荒可以试一下

NOTHING attracting

- Terrible design. All areas are empty.
- Terrible map detail
- Some textures are mixed up
- Bugs
- Unplayable if you don't fix it
Worse than troll maps. Do not waste your time on this.

Unfinished?

After reading the description, I think it's an unfinished campaign that is impossible to receive any update.

Pros:
- Clear tips till the ending
- Well ported
- Items are spawned randomly

Cons:
- Bots won't follow you after you get down to the basement, which will prevent you complete the map. Why the author refused to fix the issue?
- Part of a wall got no texture. The texture of part of a pipe are mixed up. A bed glows in the dark, Some props can't be effected by map lighting (they look dark if you turned off your flashlight).
- Lazy ending 
- No 3D skybox or something similar to help the map look better. You know, in an area, walls are broken and you can see the sky.
- After the map ended, the game played credits instead of showing game states.
- Completely no events
- Too short
- The ghost (I guess?) looked... funny. It hasn't got a suitable model XD

质量较低

场景是移植的，所以不评价（但个人感觉移植后的场景还是很粗糙的，不要只看截图就认为场景很不错）
节奏非常奇葩，没几分钟就有尸潮的那种。对的，这图全程就是没新意地堆尸潮堆尸潮堆尸潮堆尸潮，流程还较长

说下一些问题：
m1：从屋子正门出去时不往车的方向走就可能会被传送到屋子地下室（也就是一开始进来的地方），路还被封了，走也走不了，只能重开
忘了是哪一关：这关很多地方会封路，强制你打扎堆的僵尸，等到一定时间才会开放通行
m6：有扇门不知道为什么打不开，把沿途能按的东西全按了一遍也还是不行，不得不noclip
m7：仓库会给你连续来三个克，还有尸潮助力
m8：恐怕要玩过原作才知道自己在某些地方的死法
全部关卡：安全屋会有一个非常突兀的原版安全门；指引比较差；门和门框不怎么契合
其它：没有intro和outro

总体质量不是很让人满意

Very mediocre campaign

Pros:
- A little more challenging campared to some campaigns
- Not too boring
- Unusual ending

Cons:
- (Kinda) Disappointing map details
- Only a few props in an area (most time)
- Terrible lighting and color correcting
- Repetitive design
- Two tanks spawn at the same time on map 4
- Nothing attracting
- In saferooms, you won't see enough medkits or T2 weapons
- The styles of different maps are mostly the same, you can only see drains or flat grounds

Conclusion:
Play it if you have no choice

Review

Pros:
- Kinda long
- I thought the author actually made efforts to make the maps
- Custom traps

Cons:
- Disapponting map details
- Horrible optimization
- Boring design. I especially don't like the repeitive design of map 4.
- The lighting is worse than many other campaigns. Also, the maps didn't get suitable color corrections.
- There're some strange paintings in the maps... I don't like them because they slightly broke the atmosphere.
- Well, most things are meaningless.

Conclusion:
Not worth playing.

Great

First of all I have to say I like your efforts.
This campaign is much better than I expected. When I played this campaign for the first time, I thought it was just another garbage campaign because there're tanks at the beginning of the first map. This time I read all reviews carefully and found that I don't have to fight against the tanks, so I played it again. In the first ten minutes I got bored with hallways very soon. There're a number of hallways with poor detail on the first map. But almost everything got well on the next 3 maps. Surprisedly, I found the map design nice. I had a nice time walking through the city, although the detail and the optimization wasn't satisfying enough for me. Also I have to say the difficulty isn't unbalanced. As a noob, I easily complete the whole campaign on Advanced with no restart before the finale. Yeah, the only thing I disliked is the design of the finale. How can I know that I have to lift up the bridge?
Overall a great campaign, though there's still room for improvement. Love it.

Review

What I dislike: empty areas, repetitive map design, terrible lighting, low-quaility textures, horrible optimization, the collision issue on map 1, the ERROR in the finale and nav issues.

Too short

As the description said, this campaign is really short. I only used 18 minutes to complete it on Advanced.
Totally a nice campaign, but not really attracting. I also dislike a few points.
- At the beginning and end of the campaign, the map detail doesn't seem very good.
- On map 3, I threw a gnome against the wall, and then... the gnome got stuck in the wall. I didn't know why, but I threw another gnome aginst wall. This time the gnome disappered. Of course I had to skip the puzzle I was working on.
And that's all I can say.

Getting lost isn’t fun

The details are nice, but all three maps were filled with meaninglessly huge and visually repetitive areas. I think most players aren't able to find the correct path quickly. At the same time, the map design is really lazy in some ways. There're completely NO exciting events, the only thing players can do is finding the right path to the saferoom. How can that be fun when the map detail isn't very satisfying? In the finale, it's too easy for survivors to defend themselves. Any place slightly higher than the ground can be a good place to camp. Also, even after the helicopter arrived, I got lost. Not a good custom campaign for me.
Edit: "The original developer requested removal"... Gosh. Nobody really expected for this.

还行

m1的设计及格，但大多数地区很空旷，细节不是很好，指引可能也有改进空间
m2质量很低，场景重复，纯粹是通过堆尸潮堆Boomer来尝试加难度
m3的场景细节一下子就上来了，设计得也很好，但感染者居然不会爬墙？？这样的话守点难度就大大降低了……
总体还行，值得一玩

Uninteresting

This campaign has completely no event before the ending, you know what that means.
The map is very detailed, so it's unfriendly to my potato PC. The lowest fps I got is 16. 
Great detail doesn't mean no model issues. It seemed that the author have no idea how to connect the separate railings.
The ending is broken in the latest version of the game, I guess. I was told to find 5 correct computers, but the rescue arrived before I finished the task. If the ending works as intended, I think I have to prepare for restarts because there were plenty of computers waiting for me to check.
Another issue is about nav. I noticed that CI can't reach survivors standing on some short objects, that's unfunny.
All in all, it's a cheap campaign, except the map detail.

Disposable

Play it for one time, feel amazed for its creativity, then delete it.
Most areas are huge but empty, and have nothing fun for exploring. Walking through them for minutes are really boring. It takes a long time to beat the full campaign, even on a modded server with auto bhop enabled.
The difficulty may be balanced for beginners, but if you've played the game for over 100hrs, you are certain to find it kind of easy.

But the mentioned issues are understandable because, hey, it's a lego campaign! You can't expect it to be quite great.

Nice

Overall it's not too bad. I actually didn't feel upset or bored playing it (and that's why I gave it 4 stars). I used 1 hour and 55 minutes to beat it on advanced with 3 strangers. But, as other reviews have pointed out, this campaigns have a number of issues.
- Little custom content and unpleasant detail, much worse than Cold Stream. (however it's still not terrible if u don't review it carfully)
- Meaningless events and props. For example, the rowing event is, unbelievably, very short. It made me think about whether the author is deliberate to make this campaign disappointing.
- Bugs are easy to find. For example, on Map 2, the tank after the alarm event may get stuck in... the ground?
- The pace is awful. This campaign is tooooo fast-paced. I couldn't try to review it in real time.
- Hordes, hordes, hordes, hordes, hordes, and, oh, tanks. I don't mean this campaign is hard, but you have to think of the fast pace.
I only showed some issues, but I don't mean this campaign is bad. Actually, it's still better than many other custom campaigns.
It's like fast food, delicious but not pretty.

Playable

Pros:
- OK design.
- Custom content.
- Fun.
- Bots work well.

Cons:
- WTF is the poster??
- A nav issue. The first tank on Map 3 suicided during my playing.
- Bad fps for mediocre details on Map 1
- You can find some op places to camp in the finale.
- Terrible color correction on Map 1. Wait, did it really use any color corrections?

Conclusion:
Just another playable campaign released many years ago. Download it if you have no other choices.

A chanlleging campaign with no custom content

This campaign was well designed. It's really chanlleging, I had a nice hour. But, why don't you set invisible walls in the right place? Some objects look very short, but you just can't jump over them. On Map 5, after entering the helicopter, don't move, because unlike other campaigns, there're NO invisible walls to protect you from falling off the helicopter.  Also, the campaign has no intro, and the states don't work. However, overall, it's still worth playing, although it's kind of rough.

A fun campaign for Super Mario fans

OMG, it's Super Mario! However, it's not suitable for bots. Also, it's too easy. It would be worth playing multiple time on expert, but not on lower difficulties. Map design is mediocre, 2D Mario levels don't seem suitable for making 3D maps. But it's still a quite classic and fun campaign.
Yeah, it's kinda boring if you ain't a Super Mario fan.

Actually this is the first addon campaign I've ever played. Yeah, Super Mario addons are just why I bought L4D2. But time flies, and now I no longer want to play Mario games as often as I used to in the past. Oh...

Playable

Map 1 is very dark, but there're no other problems. In addition, this is the most chanlleging one of all 3 maps.
Map 2 is just easy and boring.
Map 3 actually has a nav issue. I dunno why, but during my playing, the first Tank didn't appear. I just listened to the background music until it suddenly stopped.
This is a campaign with mediocre design and detail, I don't think you should play this before playing other excellent campaigns.

This would be fun on a modded server, but...

I played this campaign on advanced with bots, although I've only played L4D2 for 800hrs.
It took me 2 hours and 8 minutes to complete it, and I restarted for 9 times.
I just want to say one thing:
ANY MELEE WEAPON CAN MAKE THIS SHI**Y CAMPAIGN EASIER

Edit: It's been some time since I completed this campaign for the last time. Maybe I'll try it again and rewrite my review some day.

不错的图，只不过问题不少

The original author is Chinese, so I think it's OK to type Chinese characters.
优点：
- 设计不错
- INFRA的风景可圈可点
- 趣味性尚可

缺点：
- 文件大小过大
- INFRA的场景不适合做战役，更不适合多特（虽然难度不高）
- 地图比例偏小（我相信看过MARCO玩家的视频的应该都知道为什么会这样）
- 没有intro和outro
- m1的强制警报车事件。。不知道如何评价
- 丧尸在已走过的地方生成
- 地图海报的拉伸很奇葩

It needs more work

Pros:
- You can pick up some props, though the system isn't as nice as that of some other campaigns.
- Nice detail.
- Kind of challenging, especially when you play solo mode.
- The ammo system is "fun" :P

Cons:
- The states don't work, and there's no credits music. A SI incapacitate everybody after i saw the text "The survivors have escaped!". Wow, actually, the survivors have never escaped.
- I played this campaign with bots. I dunno why, but the mod "Left 4 Bots" didn't work on this campaign for me at all.
Bot nav is stupid. Bots won't pick up weapons as soon as they find them, and I didn't think they really picked up any ammo when I was playing this campaign. When I was trying to find the car key, for no reason, bots didn't catch up with me quickly. When I picked up the car key, well... Louis has been dead, and the other two bots still haven't caught up with me.
- There's collision bug. (I mean, I can walk through some parts of the subway, though they should stop me. Ahhhh, f**k my poor English.)
- The map thumbnail doesn't look good in game.

Conclusion:
If the issues can get solved, it's a great campaign.
