Pros:

-Great campaign
-Great to play alone and with others (i suggest advanced for the funniest shit to happen)
-Great AI director moments, witht the rain and all
-Tunnel area is VERY fun
-When you go into the city, it is really cool (However, when you first see the city, you should hear the creepy radio's echo throughout the city)
-Has some really great coop moments

Cons:

-Sometimes, (this has happened to me about 5 times) the witch and tank spawn in the elavator shaft. It makes an increasily funny time, as they cannot escape (and when the elavator comes, they are in the floor) but it really ruins the realism of playing on city 17.
-Bots wont come back, once they move foward, they dont move backward.

Conclusion:

Really great map, small glitches, but fun altogether. Highly suggest downloading.
(Im still waiting for the creepy radio)

Pros:

-Best dialog EVURRR
-Fire skins are BRILLIANT
-The effect of it being frozen at first then on fire is great.

Cons:

-I would like it better without the tank reskin
-Had to delete it because of above
-Can crash your game because of all the fire

Conclusion:

you would only want to play this once then delete it because the tank skin ruins it forever.
