Pros:

fun to play
challenging 
has everything from the origional

Cons:

Bad AI
No Silent Hill music

Conclusion:

This is really cool to play like it is on Left 4 Dead 1 but the AI is very annoying. In its origional version the AI was annoying but this time its worse because the AI wont pick up healing items or weapons and sometimes wont shoot enemies that are too close to me. It could be better, cant wait for the finished version cuz this has always been a fun map.

Pros:

Great attention to detail
Made by a true zombie fan
Good Atmosphere
Good Challenge
Excellent Story

Cons:

Some difficulty with the AI
A little confusing to navagate

Conclusion:

This is a great map and a must get for anybody who just has this game. You can tell this campaign was made by a true zombie fan and took their time making it. If youre a zombie fan and want a little bit of story with youre zombies this is definatly the map to get. And if you can tell you can find things that show respect to the deadfather himself George Romero. I highly recomend this campaign.
