Pros:

Traps are Clever, and well-thought out.
Map is Super Fun.
Left 4 Dead 1 Survivors.
I love the room with all the buttons, because the buttons are different every time.

Cons:

Bots are Stupid. (But then again, they always are.)
Some traps a re a little redundant.

Conclusion:

Despite having it's cons, the former of which can be solved by playing with friends, and the latter of which is only true if you play it a lot, it's an amazingly fun map.
