Pros:

- Natural Disaster
- Love the Finale
- Really packed
- Not an overdose of hordes
- Left 4 Dead survivors
- Slow motion during the "Run or die" part
- Love the escape music
- NEW VS MODE :D

Cons:

- Might be just me but when you have to escape the building and the "Run Or Die" text shows, I hear Zoey saying Run instead of Rochelle.

Conclusion:

Amazing Map.  This one is in the books.  Its here to stay.  But please make it into a 4 - 5 map campaign.  1 map is a little to less.  Make it into a 4 -5 map campaign and it will be amazing. AND NOW THERE IS VERSUS!  Recommending to my friends!..  L4Dmaps need to make rating be higher then 10...
