This mod was unbelievebly good. The features implimented were amazing, however some of the levels seemed very repetative E.G teh bit underneath the parking lot. The shooting needed to be broken down into small chunks with a rest in between with a puzzle or exploration THIS ISN'T CALL OF DUTY! :D
The cutscenes were great, I've always wanted to see them introduced in a mod.
Sometimes it was confusing where to go, the hints didn't help me very much.
I rated this a 9 because the mod was at a high quallity and innovative however, felt very repetive and sometimes boring. Definitely worth the download!
