Pros:

- Fixes the Valve's damn update

Cons:

- NO CONS

Conclusion:

This update from Valve showed a total disrespect to the mappers.
Then your fix is salvation for these great campaigns
Excellent job, works perfectly! Thank you very much!

Pros:

- the teaser trailer, one of the best left4dead addons trailers 
- the intro
- the athmosphere
- different paths
- an epic history
- excellent graphics

Cons:

- lack of magnuns (found only one)
- too many special zombies (they come in pairs and uninterruptedly)
- finale too dificult on expert realism
- the sacrifice of the finale is unnecessary

Conclusion:

This is a great campaign, but the lack of magnuns are critical for me, this is the only weapon I really use. Furthermore, on expert realism, the excess of special zombies in certain parts of the maps (especially at finale) make a difficult and frustrating campaign. On the finale we need more biles.
Anyway, this is one of the best l4d campaigns (TOP 10)

Pros:

- Excellent graphics and originality
- Custom models and textures
- etc, etc, etc

Cons:

NO CONS

Conclusion:

Issues fixed! This is one of the best campaigns ever made! Congratulations!

Pros:

- New features: making own molotovs and pipes, electric water, etc
- Different routes

Cons:

- The end of the first map is very difficult on expert, it is mandatory put a bile for use in this part

Conclusion:

This is a fast campaign, very well balanced, except in the finale of the first map (needs bile)

Pros:

- excellent and original graphics (great design)
- original environment

Cons:

- not enoug ammo and resources (pipe, molotov, etc) on map 2
- rescue helicopter is very slow

Conclusion:

This is one of the most unique campaigns released for L4D2 lately, and an excellent challenge on expert level. Go to my list of playable campaigns on expert. Thanks to the author!

Pros:

- Excelent gameplay and difficulty
- Great environments and a great finale with storm and dark atmosphere

Cons:

- Level 1 is too short

Conclusion:

This is a great port of a Left 4 Dead 1 campaign!
This campaign meets the need to play Left 4 Dead 1 campaigns!

Pros:

- Great levels, well coordinated
- No bugs , lots of place to explore
- Excelent finale
- Good atmosphere

Congratulations, one of the most original L4D2 campaigns!

Cons:

Conclusion:

This is one of the best Left 4 Dead 2 campaigns, an epic adventure in different and beautiful environments. Need some tactics at times, but this is the challenge. TOP 10

Pros:

- Incredible design
- Incredible detail level
- Unique atmosphere, looks like you're in a movie!

Cons:

- The only problem I noticed is the level of difficulty: very easy in NORMAL or even ADVANCED. This campaign needs to be more challenging, more hordes, more zombies to kill!
- A map from the previous version was removed, a map that started in a labyrinth of rooms and then went to the shopping and the supermarket. I guess it could have been utilized in some way, especially the part of the mall...

Conclusion:

*** THIS IS THE BEST LEFT 4 DEAD 1 CAMPAIGN! ***

Please convert to Left 4 Dead 2! :-))

Pros:

- Original environment with great graphics and illumination (maps 1 and 2 remember L4D1; maps 3 and 4, with daylight, L4D2)
- Many crescendo events
- The platform is very cool (note: 100)

Cons:

- Finale map: more ammo

Conclusion:

Excellent campaign, perfectly well converted to L4D2.

Pros:

- an epic adventure that takes place in several different locations
- great graphics design and illumination
- the "bridge that explodes" event is very cool
- all the maps are very cool

Cons:

NO CONS

Conclusion:

this campaign is epic, a great adventure in L4D2 world, deserves all the merit.

Pros:

- ORIGINAL
- great graphics design and illumination
- the bridge event is very cool
- the swamp map and the suspended house in the tree deserves note 100 (very creative and original)

Cons:

NO CONS ("infinite hordes" problem fixed!)

Conclusion:

excelent campaign!

Pros:

- Good graphics and illumination
- Great atmosphere, reminds L4D1
- Correct use of crescendo events (what most campaigns do not make)
- Very challenging (situations in which appear 2 same special infected at a time)

Cons:

- No cons

Conclusion:

This is one of the most original campaigns since its release to L4D1.
Even before L4D2, already presents a rolling crescendo event (final of the map "DTA2 Hill" from L4D1 version). With the addition of the fourth map, became perfect.

Pros:

- excelent idea
- beautiful graphics with daytime illumination

Cons:

- no cons

Conclusion:

This was one of the first L4D1 campaigns modification. One of the best!

Pros:

- Great campaign with perfect graphics and daytime illumination

Cons:

- Lack of typical L4D2 rolling crescendos
- Too easy in coop mode
- Too many ammo and weapons
- Does not require melee weapons

Conclusion:

In L4D1, this is one of the best add-on campaign, but in L4D2 is too easy, and offers little challenge. 
This campaign does not require melee weapons and should be better adapted to the L4D2 universe. 
For graphics and originality my note is 100, but regarding gameplay is 85.

Pros:

- Excelent conversion ideia
- Perfect graphics and illumination
- Good spots to fight the hordes

Cons:

- No Cons

Conclusion:

Excelent conversion! Perfect for HL2 fans!

Excelent survival map, one of the best!

Pros:

- Excellent choice of music

Cons:

- At the moment, no cons!

Conclusion:

This is a great campaign for L4D1, but a PERFECT campaign for L4D2!
One of the top L4D2 addon campaigns.

Pros:

- Original 3D model and textures
- Good locations

Cons:

- Not much detailed
- Lack of good L4D2 crescendo events
- Dark lighting in some places

Conclusion:

This is a good L4D2 campaign, but needs to be improved.
