Pros:

- Japanese campaign with a lot of their culture.
- Customs textures everywhere and in all maps, i'm amazed.
- Incredible level of detail on all maps.
- Good environment variety.
- All maps are very well designed.
- Color correction in map 3 is awesome.
- Good and fluent gameplay through the maps.
- Some nice and innovative ideas like the ambulance safe room and the chair lift travel.
- Big maps with a lot of ways to go and explore.
- Relative good placement of the supplies.
- Use the L4D1 survivors, thanks a lot we need more maps with them.
- L4D1 horde music and intro.
- All maps with a dark and atmospheric feel.
- Good use of dialogue.
- Nice crescendo events.
- Finale is really cool and interesting.

Cons:

- Some missing music, safe room, ambient music (Rabies, glimpse, etc). I'm still hoping to some Japanese  music for this campaing.
-You get lost sometimes because the big size of the maps, but not so bad since you could explore more places.
- You can't grab the golf club on the start.
- Infected get stuck on the start of the last map,.
- The sniper are given to the players to soon i think, the map 1 should have only tier 1 weapons.
- Needs some performance improvements.
- Summer zombies don't fit the campaing well, it's not your fault on this, but you could maybe use some of the Passing common infected, or maybe include that new mod who brings back the L4D1 common infected.

Conclusion:

(Updated review) What i can say? I'm an amazed, i never see a custom campaign with high level of detail like this one, custom textures on every place, and a dark atmosphere, Japan feel and an incredible campaign, this campaing right now is the best custom campaing so far for me, really awesome.

Pros:

- Nice works on details, far more than the original ones
- High Definition textures
- Realistic models
- Fits the game

Cons:

- Just way too colorful for my taste

Conclusion:

Great mod, again you bring to us HD textues and realistic modelss, thanks, my only complain is the colors, but is nothing big, nice work.

Pros:

- Very good designed campaign
- Very detailed, with a lot of custom textures and models like the CEDA boxes and Hazmat workers
- The graphics are great
- The maps are long
- Very good use of the survivors dialogue
- Gauntlet crescendo in L4D1
- Is a challenging campaign
- Some "traps" in some maps
- Is very atmospheric, specially the first map, just loved
- For L4D1, nice to see people are still making good campaigns for this game
- Fits the story.

Cons:

- No intro, ambient and saferoom musics, but i' think will be fixed, since still is a beta
- Some visual bugs in some custom Textures, like the CEDA boxes and some pictures on the walls on the end of the Gauntlet event in the first map
- The Gauntlet event is a little confusing at the start, i think some tips or some survivor dialogue to run would be nice
- The event on map 3 is really hard, maybe some throwables would help.
- Some extra dialogue lines could be added through all campaign, although the dialogue lines are already nice
- On finale you can have some trouble on preparation time, since the hordes and special infected is always coming constantly.

Conclusion:

Really a great campaign, very well designed with a lot of custom content and originality. I specially enjoyed the new first map, is really great the new night setting and enviroment (lots of L4D1 style), the gauntlet event is nice too, i hope the last map that you are working also be outside, at night, all other maps are also great and challenging too, really good. 
Can wait to play the finished version of this, nice job and keep the good work.

Pros:

- Better color tones, more darker and grittier
- Fits better on every campaign, specially the original L4D1 maps
- Works fine and works online

Cons:

- The bullets decal that do not show up
- Don't work on official server, but this is not your fault

Conclusion:

Thank You very much, i was looking for a mod like this for a long time, i always prefer the original saferoom door, it have much better color and is more darker and fits better for every campaign, Valve should bring back this door, at least, for L4D1 campaigns, the only problem that i find is the bullets decal.

Pros:

- Fix the hands for every weapon including the pistols, magnum, melee weapons and adrenaline shot.
- Work with your reanimations.
- Works online

Cons:

- Sometimes, very rarely the fingers still may clip through the melee weapons, pistols and magnum, but is nothing big.

Conclusion:

Thanks Arby for once again fixing the game for us, thing that i doubt Valve will fix, thank you again.

Pros:

- Nice walking animation
- Awesome Reloading animations
- Feel better and nice than Valve's default animation

Cons:

- None

Conclusion:

Once again arby's delivery to us a awesome mod, is simple awsome, now i like to use the grenade launcher.

Pros:

- Better weapon position on the screen

- Better walking/running animations

- Better Idle animations

- Reload/Melee animations

- Far better than the original

Cons:

- For me helping/item grab hand are a con since all your other weapons have a animation for this.

- The original animation when you grab the SMG or you switch from your secondary weapon to the SMG is better and have a sound

- Perhaps the positioning of the gun when stopped/idle can be a little higher up on the screen

Conclusion:

Once again you deliver us a awesome mod, much, much better than original, congratulations, i just love it, the only thing is really the hand for helping and grabbing items that you need add, excelent job.

Pros:

-Nice Atmosphere
-L4D1 survivors
-Dialogue
-Great design
-Custom intro and safe room music
-Cool new intro level
-Cool crecendos and surprises
-Custom weapons

Cons:

- A little better weapons placement
- Put No Mercy horde music for a better atmosphere.

Conclusion:

A great campaign, is just awesome, i love the dark atmosphere, nice places and surprises, the only thing that i would like to see is little more weapons variety, especially in the map 1, also put more magnum spawn in that map. Other thing i would like suggest is put no Mercy horde music and ambient sounds("rabies") instead of the Sacrifice ones.
But on general is a awesome campaign, nice job.

Pros:

- walking animations
- nice reloading animations
- far better than original

Cons:

- none

Conclusion:

This mod put Valve's animations to shame, they could make this mod official

Pros:

-very fitting for Rochelle
-nice white shirt
-nice face details like the lipstick

Cons:

-none

Conclusion:

A simple skin, but a well done skin, one of my favorite Rochelle skins.

Pros:

Cool red shirt and nice black suit
Very fitting for Nick
works perfectly

Cons:

none

Conclusion:

Simply best nick skin so far, deserves 100
