Pros:

Follows Silent hills key points almost exactly.
Lengthy, perfect for people who like that sort of thing.
Creepy, had me jumping a couple times.
Has the good old silent hill feel.

Cons:

Some of the boss fights felt like a cop out, i understand custom bosses are hard but the extra work would of helped.
As i stated as a pro, it's long. This is also its con because dying is very very VERY likely to happen, even on easy.
Not many good weapons to start with. But then again thats how the real game was as well.

Conclusion:

Honestly, this is one hell of a good map. Its long, which is wonderful to me, and has four endings scenes that can play out depending on what you do and what not. If you don't like this, i can recommend  silent fear to you, a shorter map with the same silent hill feel and a custom boss. But to those who like a lengthy, challenging, and generally spooky and scary map, download this :)

Pros:

-Looks great
-Wonderful animations
-a step up from the bland original pistols the game provides

Cons:

Can't think of any

Conclusion:

This proves that simplicity is often better than going all out :) well done good sir.
