Pros:

-BEAUTIFUL
-Lovely details
-Meticulously designed layouts
-Great atmosphere- the church without music was just absolutely haunting.
-Secret area
-Lengthy and never boring

Cons:

-Bot navigation needs work, especially in secret area
-Finale horde doesn't stop when Tank spawns
-I don't like the 2nd finale tank spawn + horde. I think the tank should be removed.

Conclusion:

This campaign is pure gold. It's up there with Suicide Blitz and I Hate Mountains. I loved every minute of playing this wonderfully beautiful and spectacular campaign. The stunning level of details and the custom textures and props, and the lighting, and the skybox... I can go on and on.

One thing I have to mention: GO DOWNLOAD THIS CAMPAIGN AND PLAY IT NOW. It's so good.
