Pros:

-good map&enviroment
-no lag or missing textures
-fun
-a long campain

Cons:

-to many zombies
-on the map 2 the tower s door dont opened
-at map 3 floating ammo
-no throwers & medkit at finale (sometines)
-the finale was long,the tank spawn 5 sec after killing the other
-a little a bit confunzing

Conclusion:

This campain is very good.I recomand to play with firends,but are some bugs that should be solved soon.I give 3-3,5.Good job so far
