Check out this video where the executive producer of Dead Space, Glen Schofield, talks about the strategies of taking out enemies in the game by dismembering them. I like the concept of being able to immobilize enemies and changing how they attack you. Ninja Gaiden 2 was pretty good with this aspect of gameplay as well, you could cut an enemies arm off and he would still try to attack you until it couldn’t anymore. This will definitely add to the horror aspect of Dead Space if you have dismembered monsters chasing you around a space station.
