It's not as shit as I thought - but I wouldn't be able to stomach it on a real difficulty level. I can see now why the graphics get so much praise, I appreciate the setpiece design, etc. But really, every fight boils down to a shooting gallery. It's really annoying to see these clusters of 10 guys running around all over the place without any purpose, constantly pouring out of the same door.

I wish it had co-op, then I'd go for Veteran or something.
