Pros:

- Map design and layout are excellent.
- Open spaces are large.
- Easily one of the best campaigns I've played.
- Fun.

Cons:

- None that I can think of.

Conclusion:

This gets a 10 from me for one simple reason:
- The horde streaming down the bridge behind us after we started the forklift. An absolutely awesome game moment. It was cinematic, like something that should have been in World War Z. 

Play it and you'll find out.

Thanks for all your efforts DannBo, they are very much appreciated.
