Pros:

-Great design, it looks great

-A general survival game plays very well on it

-Weapons and supplies are nice and simply laid out

-Access to new rooms as time goes on makes things more interesting

Cons:

-The way to start the horde could be difficult to find for some people (Although that's a given on all custom maps)

-The infected have a little to many ways to attack you from. A smoker can easily pull you off while your concentrated on where all the zombies are more frequently coming from.

Conclusion:

A very well done map. I really enjoyed playing it. It's pretty difficult but it give you a nice challenge.
