Pros:

+Very well designed map
+Accurate copy of the attraction
+Nice to play, with a good amount of supplies
+The Scavenge mid-in ride is surely a nice idea
+Interesting idea of finale
+The traps are another nice deal added in this campaign

Cons:

-The ride is WAY to long, if you (and this happens commonly) die in the Scavenge portion while playing Expert it's highly frustrating to do the ride over and over.
-Tanks and Witches get stucked easyly

Conclusion:

A nice map, even for people not knowing the original attraction.
It includes some nice and creative inventions/traps and a good use of the Scavenge mode.

I think it's worth a full 90
