So, when I played through this map I had textures missing because I didn't have the fifth part installed (I downloaded it a while ago and I assume the fifth part wasn't out yet). But I decided to play it anyway and even with half the map looking like garbage it was a blast to go through. I learned early on that healing was scarce, and that made it that much more gratifying when I found some. In addition, it encouraged me to backtrack quite a ways to resurrect a teammate when I found a defib because I was never certain how much more was ahead of me.

The maps are diverse in terms of theme, if not a bit all over the place. They transition well into each other for the most part, and it really got my imagination going. Each map has unique mechanics as well. My favorites were the automatically opening doors and the generator-powered blades in the finale. Overall this campaign is nice if you like to explore and don't mind a bit of a challenge. I plan on going through the maps again for the full experience.
