Audio is a mixed bag. The continuing groans of the zombies get annoying in short order. It makes plugging them full of lead a satisfying job, but I'm not sure that's what the sound people had in mind. Furthermore, you can still hear them when they're three screens away. That's good for mood and suspense, but it's unrealistic.
Music is excellent.
A wonderfully tense and horrific mood is evoked by the understated piano score. Voice acting is abysmal. Sure, it's funny, but in that unintentional way that made me embarrassed each time Leon opened his pursed, Japanime-style mouth. You got it. I had to reset my preferences about every third time I started the game.
