Pros:

Awesome Details!!!
The beginning with baby crying scared the crap out of me. (good)
The npcs in the church were perfect for this campaign.
Loved that it took place in Barcelona.
Liked the custom zombie.
The subway tunnel with the cars falling in on top of you, priceless detail.
The Leg O' Lamb that you could use as a weapon.
Escape video was awesome.

Cons:

The custom football fan zombie did not bleed.
Also whenever he died, a black square appeared around his body.

Conclusion:

Best campaign I have ever played. Better than Wan Li. Better than Suicide Blitz 2. I loved this one. You should make some more of these awesome campaigns. Make one for France, or Germany, or even New York. Dude, 100% score. If I could give you a 10000, I would. IT'S OVER NINE THOUSAND!!!!!!!!!!!!!!!!!

Pros:

I like the suspense that I felt whist playing this campaign.
The detail was very good.
Loved, LOVED, the Cinema area. It felt appropriate for this campaign.

Cons:

Tank flipped out and committed suicide every time.
Need more choices for weapons in the beginning of the map. (I died like 4 times) *i'm a l4d veteran*
The darkness was too much, couldn't see anything.
Slaughter house meat room had the pink and black checkerboard of untexturedness.

Conclusion:

This campaign was very good. Still needs some work, but it was good. The darkness made me feel scared at some points in the first map. Offices were way too dark, add at least some damaged but working overhead lights to make the room at least dim. I say this campaign is really good. Just add some more details, fix up the bots, and voila, you have a good campaign. Hope it gets better.
