It's important for the horror genre to effectively create the correct sort of atmosphere in which the player is constantly cautious, hence being fearful. Dead Space 2, being a third-person shooter, has a significantly harder time with that. The common problem is allowing the player to look around corners, or behind the character whilst moving forward. Unfortunately the developers added more conveniences for the player which effectively spoils the horror. Though Dead Space 2 is a decent shooter, it doesn't make players scared..
