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.

Pros:

Each level was visually very detailed and looked great.
Huge, open areas.
The shopping mall was awesome and massive.
Great to explore as each area seemed to be endless.
Each level was of good length.
Plenty of med kits, weapons, ammo and throwables which we always approve of. 

Cons:

If there was anything, we didn't notice as we were having way too much fun.

Conclusion:

We all agreed that this was one of the best campaigns we'd played for quite a while. There was only three of our normal foursome today and we are all waiting for Rochelle to get back off his hols so we can play this again together.
Four or five tanks spawned all at once in the finale just before the train arrived which scared the pants off us, but we all survived and made it out, so it can't have been that bad.

We game for fun, and this was fun. 

Thanks for all your efforts, and I hope you make more campaigns that are as big and open as this. It is one of the reasons this was so good to play.
