Crossing Over

Pros:

~~~Overall~~~
-I loved the farm setting. It was very realistic and spread out.
-There was some nice dialogue between the survivors. 
-The crescendos were unique and fun.
-I loved the school evac. center, was very creepy.
-The custom content was all good. The notes found in the school seemed very real. 
-I think the length of the campaign was perfect.
-There was enough ammo and health for my liking. 
-There were good amounts of hoards, specials, and tanks.
-There was no direction, which normally I wouldn't like, but I think it fit the rural, realistic farm setting. If you've ever been lost in the country, there aren't many signs telling you where to go. 
-The farm houses were nicely done

Cons:

~~~Map 2~~~
-I accidentally got behind the barb-wire fence, and was able to see behind the map into the gray areas. 

~~~Map 4~~~
-AI were a bit buggy on the silos. 

Conclusion:

This has been one of my favorite campaigns on L4D for realism. I thought the similarities to a small farm community were great. The crescendos were very creative, and the custom content added a lot. The finale was unique and made for an interesting ending. I only found a couple small errors, other than that, it was great!
