Pros:

-Creative level design
-Great use of fog/ash (added tension)
-Balanced amount of infected/undead
-Randomly generated glyph hunt
-90's survival horror atmosphere/concept
-Good fun

Cons:

-Single player bots can't follow most paths
-Too many pick-ups (health/guns etc)
-Some special infected become trapped on objects
-The final boss' aesthetic design doesn't suit the atmosphere
-Too short

Conclusion:

This is a great little mod, which was a pleasure to play. The overall atmosphere was just right and I wanted to continue playing long after the final boss. A lot of talent and imagination has obviously gone into the making of this, If you're a fan of silent hill, resident evil or 90's survival horror in general I recommend you give this a go. Thanks Mr.Sierra for building something, (albeit extremely short,)  that was more engrossing than most current triple A titles.
