Very nice campaign.
I love the graphics, the darkness, all the references to the horror movies in the catacombs section including shadows, sounds etc. and the easter eggs :) I play this quite often cause it's fun to play, I just experience some fps drops in some places but it might be my own problem. I don't like the beginning of the 4th chapter after the latest update, but it's a matter of taste, I liked better the way it was before which means I am probably going to roll back to the previous version, also cause the people playing with me don't like it either. Very good job anyway, glad people still creating nice maps for this game.
One of the best addon maps!
