Pros:

(Maps 1-3)
-A lot of Horde events, I like that.
-Nice Detail
-Nice supply layout
-Custom horde event, the tree falling on the car
-LOOONG campaign
-Survivor dialogue
-Challenging

Cons:

(Maps 1-3)
-Too many throwables
-A little more pointers

Conclusion:

This campaign is challenging, meant to be played with friends. Play on easy if playing by yourself. I actually died a few times, playing with the AI on normal. I love the campaign so far, soon going to do another review on the next half. So far I recommend this.
