Pros:

genius use of texture
good use of space
Love the transitions
A lot of action, no time to sleep
epic final

Cons:

- too short (but very pleasant short time)
- weapons spawn are too far to each other.

Conclusion:

Spent 40 minutes with friends on it, EVERYONE love your work!
I want to see more. Waiting for the next project! Yes!!!
You have three fans here.

Pros:

++variety of maps (no one is similar) and a genius variety of ideas (differents ways, differents strategy) 
++textures and Gifs. Touristic map. a lot of picture must seen.
+"the Grange" music
+the magic flag with the Park & recreation SHIELD, LOL !!
+Ron "!@#$in" Swanson, I'm a huge fan! So cool to hear his voice.Triple lol.
+ love the Maya pyramids!! I saw them, it's the same.The giant tank is fun.
+++ very "bizarre" map and surrealistic world.

Cons:

--no scenario
---very hard. too much traps.
-too much tank (for the experts)
-Unfinished map, maybe need a coherence between architecture.
-the first map is not elegant (but very scary sometimes). The lights are randomizes
- weapons "error" (seems to be a melee weapon bugs)
- The final battlefield has too much infected, the game lags...sometimes.

Conclusion:

A very strange and fun campaign. It's a great and very big job for a first campaign. I want to congratulate you and encourage you to continue this map, optimize it and use the cons. 
Waiting for the FINAL version! Yes!

to Slamalt92: I met a lot of Jockey, Boomer, Splitters,etc... 

Pros:

not agressive for the eyes
for the minecraft fans
play twice, single and with co-op = same pleasure
the town is very beautiful

Cons:

the boss is not very scary

too big for some maps

Conclusion:

For the Minecraft fans... A lot of fun. It's good to play the same game but in an kind of other dimension. Fresh and delighting.

Pros:

a lot of Tank.
simple map
crazy zombies in final

Cons:

ten minutes not enough
very hard to escape in Normal 
too big map
bugs with tank spawn some moments.

Conclusion:

Want to see others maps with this kind of idea!
