Pros:

-Environment is enjoyable
-Enough amount of supplies
-Fantastic music!
-Vast areas to explore 

Cons:

-Slightly too loud music

Conclusion:

Overall a great campaign. Really loved the music! Even if it was a bit loud. I rather have music than no music at all.
Finale area was big enough. Was actually quite easy to kill the tank luring him with the turret. 

Pros:

- Lots of action
- Long campaign, even though all maps aren't done yet
- Smart use of "traps" 
- Survivor dialogues
- Interesting events

Cons:

- Lack of throwables in some maps
- Can't get ready for the finale due to constant zombie rushes and specials 

Conclusion:

A campaign I will play many times, like the tension and the difficulty. 
Quite hard, forced me into using health kits again :P.
Just minor issues that need to be fixed.
I look forward to playing all the 5 maps together. 

Pros:

Great variety 
Love the cabin zombie rush
Fun being surrounded by zombies while riding the boat! 

Cons:

Not much:
My only issue was with the bots. They can jump in front of the turrets and get themselves killed, or sometimes not be fast enough to get on the boat/truck. At times a little disoriented, but if you are at least 2 players it is not a big problem. 

Conclusion:

Different maps with lots of variation so you don't get bored doing the same thing over and over like in some other campaigns. Must have been difficult getting the bots to get on the trucks and boats?
