Pros:

Cool Icons
Cool Background
Cool Music
Nepeta

Cons:

The Song feels too interrupted
A Video as a background would be cooler

Conclusion:

Cool

Pros:

-Feels like a Silent Hill
-Very Loyal to the actual game
-Balanced infected
-Low ammounts of ammo and weapons
-Looooooong
-Forces teamwork
-Only one map in the first level (Force you to take a piece of paper and copy it so you don't get lost so easily)
-A lot of effort in the construction of the levels.

Cons:

-Laberynthic levels
-A lot of places look like the same
-Ending
-All the zombies spawn in the top of buildings...

Conclusion:

One of the best campaigns I have ever played. But, seriously, my head hurts, wouldn't you mind to put more maps or places to guide? Like mailboxes or something.
