Pros:

Long Campaign
Nice Maps
Interesting Place
Many infected to kill

Cons:

Very low ammo pile
Very low medikits/pills/adrenaline
The alarm counted multiple times
The ways were sometimes very difficult to find
Some doors were not open or mutilate.

Conclusion:

The name says it all. There were many infected as to kill. However, it quickly goes out of ammunition and one which is rare. Along the way there sometimes for collecting weapons, but even they are rare. Medikits, pills or adrenaline is also found less frequently. I almost killed more zombies with the Katana than with firearms.
Also, I could not open some doors, and I could not destroy it. That was only possible through the special infected or the normal infected.
