Pros:

Awesome map with great detail
the broadcasts about the zombie apocalypse were a very nice touch.
DAYLIGHT!
Awesome intro and ending.
Very fun to play.
Really felt like I was in the movie Dawn of the dead.

Cons:

None that are worth mentioning.

Conclusion:

Pay close attention to this map creators, because this is how it's done. No endless hordes. No Witch every two feet. No back to back Tanks. Just a well designed, well put together map that is just fun to play.

I'm giving this one a perfect ten.
