It's not guro. There's some grotesque CGs(computer graphics), but not really any mutilation. What makes it scary is the psychological aspect of being trapped. You empathize with the main character despite their horrible actions. You're dragged right into it with him. You also get to the see the normal world from other character's perspectives, which prevents you from getting used to the main characters distorted view of the world. Don't read the American comic. It totaly misses the point and waters it down. The visual novel is a classic, plus it's sound track really helps set the mood.
