I started playing Dead Space and like the "Cut off the Limbs" idea. I only have the Plasma Cutter and judging by this answer it is fairly important.
While playing, I noticed I could change the orientation between vertical and horizontal (not sure if future weapons will have this as well). Which of these is more effective? I've been keeping it horizontal to blast both legs at once, but is this the easiest way to kill enemies? Perhaps I am missing a more effective vertical-oriented strategy.
I'm mostly worried about the fact that games like this tend to have things hiding around corners and creeping up behind you. If horizontal/vertical it more effective, then I can default to that so I don't have an extra step when I get surprise ambushes.
