Hmm... something's not quite right...
Animation wise, this is definitely a step up, and the previous Madness...es were already quite nice. But it feels like something is missing. I can't quite put my finger on it, but the best description I can offer for that vague complaint would be... the sense of urgency.
Maybe it's because we're told in the beginning our hero is undead now, which means he can't really die, but the fights, while well done, seemed lacking. He just plowed through room after room. Granted, he always does that, but usually it looks like it taxes him more than it did here. The enemies didn't get in his way to the same extent, I think. He certainly went through them faster, especially on the train where he just seems to run and gun. Sorry if this isn't clear, I tried.
