According to ESRB, this game contains: Blood and Gore, Intense Violence
Parents should keep their children very far away from this game. Not only is it scary and horrifically violent, the subject matter is enough to make me uncomfortable at times, and I'm one of the least flappable people around.
Horror fans should check this game out, it's a different kind of horror game, but in this case, the change was definitely for the better.
Deaf and Hard of Hearing gamers will be sorely disappointed, as the game offers no subtitling of any kind for its massive amount of dialogue, which renders the elaborate plot incomprehensible. They'll also miss out on a copious amount of audio cues, which will make playing the game much more of a chore than is should be.
