Dead space is all about the fear factor and suspense and plenty of chills with darkened corridors and all the stuff which made Dead Space a better game than the once famous Resident evil before it.
This is spot on.
Also, I have to admit that I never quite finished Dead Space. As good as it was, the other thing it shared with Resi was the poor move/shoot mechanics. Brilliant atmosphere, but slow and cumbersome at times as well.
I have very little interest in even trying the latest incarnation.
