Pros:

-Really fun and difficult campaign XD
-It has that good ol' horror element to it that satisfies me
-Brings a fresh type of game play aside from the same old "let us kill all the zombie we see on the way to get rescued"
-The whole "silent hill" feel is true to the game, especially  with the added help of the audio file.
-I love the how this campaign stresses you to find your items at the cost of summoning a horde
-The scarcity of weapons and ammo made this extremely fun on realism.

Cons:

-The map takes forever to load and occasionally crashes
-The bots (on some parts) act stupid and don't follow through towards the intended goal.
-This map sometimes will require you to turn off certain mods.
-This map HAS to be played with friends XD (this really didn't deduct any points it is just my opinion) 

Conclusion:

Well I have had a blast with this map, it is fun (with friends) and is not intended with anyone who isn't patient because this map does require a lot of back tracking.  If anyone is looking for a challenging map then you come to the right place, again for 100% fun-mode play it on realism. :3
