Pros:

-3 Big maps
-Many details
-Subsurface is glaucous
-Very good architecture
-Immersive campaign

Cons:

-None

Conclusion:

Only 3 maps, but three big quality maps.
Decors immerse us perfectly in different atmospheres.
No bug (or so I have not seen them, very discreet ! ^^), no lag, bots are not stupid.
Large rooms are really well done. The subsurface is glaucous as hell, cool ! :o)
Overall, the architecture is very well done, textures are carefully chosen, the path is well thought.
The final is quite surprising but effective.
Personally, I loved the ending video.
Hard work and excellent results. Congratulations ! :o)

Pros:

-Very good quality architecture
-Very good job about textures
-Sounds, noises, voices, screams (mob)
-Ambient sound like Silent Hill
-Oppressing ambient
-BIG maps !
-Puzzles
-Musics of Silent Hill
-Skins and models ! (Survivors, weapons and mobs)
-Much more...

Cons:

-Some graphics bugs (map #6)
-For me (but not other who played with me), no text puzzle.
-Final too too too small :'(

Conclusion:

This opus is at the same level that your first campaign "Silent Hill 1".
This campaign has given me want to play Silent Hills, again. :o)
The atmosphere of Silent Hill is omnipresent : the image, colors, sounds, noises, musics, etc. Patience is waiting for you ! Cool ! :oD
About monsters, I find them really succeeds. Skins are really good made, the models (jockey, hunter, witch and tank) are really really good! Their sounds as well. My favorite is the witch. :oD
Weapon models, weapon sounds are faithful to Silent Hill.
Overall, the textures are successful, a very good job, a lot of work !
The architecture of cities, rooms, parts is very similar to Silent Hill. The large areas in the fog are perfect.
However, the map #6 is totally out of context. What's happening ? (I say no more to avoid spoilers...). This map (#6) has some display bugs, lag (due to the changing environment ?).
The maps #7 is too short for my opinion. A little more information would not be too much.
Anyway. Lot of work for a very good result. I would have rated 10/ 10, but the map #6 lowers the note.
Thank you for this great campaign, and continues like this, I'm looking forward to play the followings...

Pros:

-Good ideas
-Many hordes
-A lot of supplies

Cons:

-Too many hordes
-Too many tank at the same time (fun... but just a moment...)
-Boring architectures
-Some bugs

Conclusion:

The basic idea was very interesting. However, the overall architecture is quite boring, at moments tiring, and other really annoying.
But this is only a personal opinion. The problem is that there are too many hordes, too many specials, popping up anywhere at the slightest movement, at the slightest action.
Sometimes there are so many zombies that they're making bugs on the doors who remain ajar. Sometimes a tank appears in the middle of a room, like that ...
The maze should be more difficult. This is just my opinion.
Good ideas, but some could be reworked...

Pros:

-Great attention to details
-Big maps
-Non linear
-Very good architectures

Cons:

-No

Conclusion:

Waow ! What a campaign ! 
Sometimes houses are true mazes, which is very interesting, it changes the usual linear path that we can see. The architecture of houses is very well developed. Many details have pride. The exterior decorations were created with care. The zombies are not stupid (and bots too! Cool !), and the hordes are effective !
For a beta, it's a success.

Pros:

+Good work
+Snow really nicely managed
+Sliding on the ice ^^
+Great maps
+Chinese musics
+Sounds

Cons:

-Too short
-Final too short
-A little bit too easy.

Conclusion:

I don't know if the Great Wall is faithful to the true (=^_^=), but it was a pleasure to play.
Chinese musics are good.
The snow is placed correctly, the textures do not overflow of solids.
The plane is pretty well done, interesting sounds impeccables, too bad that we don't see survivors jumping in clouds. ^^
The final pretty cool to do, especially on a very slippery ice.
We regret that the campaign is a bit short, and too easy.
But let's wait and see the final version. ;o)

Pros:

+Great/big maps
+Very good architecture
+Interresting details
+The zoo
+A big final

Cons:

-Some bugs, only if we linger on.

Conclusion:

The architecture, texture management, and optimization are the strengths of this campaign. The maps are large, without any lag (even with a horde + puke bomb + Molotov ^^). The zoo is especially well done, the greenhouse also. The details are cared for. Triggers are interesting.
Sounds, textures, and the weather are well managed and immerses us in the context.
Storm surges that push the survivors, good!
In the first map, helicopter drop-off is good managed, and a good idea. The dynamic roof is nice.
A few minor bugs at some trees, and the elephant.
The finish is endless. I like it. I've cought my breath at the end. The two paths (air and ground) are a plus. In Expert mode, the adrenaline is flowing in our veins, a lot! ^^
A real pleasure!
Good job.

Pros:

+Great job about architecture, texture.
+The length is very good.
+Not too many item: weapons and health are good placed.

Cons:

-The final is short.

Conclusion:

There is a great work of architecture, gameplay, and scenario. The maps are large enough.
The work is cared and meticulous, it's very enjoyable to play.
In my opinion, I think the end is too short, and too easy. The credit's music is ... strange (but this is only my opinion ^ ^). Good job.

Pros:

+Great quality about architecture.
+Sounds are very good !
+The oppressive atmosphère.
+Ghost are perfect.
+Haunted house is amazing !
+The final: GREAT !

Cons:

-Too easy because too many ammo and weapons.

Conclusion:

An excellent campaign.
Noise's ambiance is very well measured, ghosts well chosen, and presented  properly.
The forest is particularly frightening as wish (great!).
And architecture of the house, and textures, demonstrates a great job and care. The paintings are interesting ! ^^
Overall, good management of the rendering engine.
4 Maps is a lot of work, we would have liked it to continue a little bit longer. o)
We hope the next ! ^^

Pros:

-The spirit of Silent Hill is here.
-Great job about the architecture.
-Dark and fog are oppressive and claustrophobic... Great!
-The drop areas are impressive.
-Puzzles are nice.
-Not easy to still alive. "Too easy game, bad game".(JD)

Cons:

-Few bugs who need some minor fixes.
-Like in the game (L4D), bots are dumb. Can't possible to fix it !

Conclusion:

Great great campaign !
We can really feel the atmosphere of Silent Hill.
The alternative world and fog are great, like in Silent Hill!
The lifetime is as interesting as in the original game. At least we will not fall every two seconds on weapons or a health kit the difficulty of Silent Hill is present because of it.
Puzzles are nice, not as difficult as in Silent Hill, but still very interesting.
Too bad that at times the rendering engine does not follow the quality of work provided.
A very good/great job! Bravo!
