Pros:

+the frozen interface of the character you choose
+snow texture and snow storm effect
+slippery ice blocks
+areas full of supplies
+plenty of useful spots, we survived 10 minutes in the start area only with 2 bots but in 4 human players we could make it better
+the crashed vehicles give the feeling of a dangerous place caused by zombies and snow storm

Cons:

-i sincerely have no cons for this map. it's good

Conclusion:

a very nice map not too hard and not too easy. nice work :)

Pros:

+excellent lighting
+interactive thunderbolts
+the tornado destructive power it's pretty well done and the music of the escape and of the safe plaza it's guessed
+the final with 8 survivors it's epic,and with all those supplies,flamethrowers,gas cans,light generator etc..
+final minute of resistance it's awesome
+all songs and musics in the map are practically amazing
+funny suiciding zombie saying "i hate my life"
+fixed barricades bug
+realistic palace collapse

Cons:

-after the tornado escape i found out that inside the apartment nothing happens,can you add a vast amount of deadly flames? so nobody can't get back anymore 

Conclusion:

just the best campaign i ever played.im happy that your campaign won the contest, it deserved it

Pros:

+big enough to run away,plannig a tactic and put the tanks
together to take them down easily
+competitive map
+enough supplies
+there's a bridge near the start location composed by glass
so you can attract 1 or more tanks and make them fall in the water by shooting the glass, it's ingenious

Cons:

-like i said supplies are enough but i think they are too distant each other 

Conclusion:

anyway they are all small cons,i like how this map is structured and how much is competitive against all those tanks,keep working on maps like this :)
