Dead Space was designed with one key point in mind: to put some good old-fashioned fear into you.
The game does everything possible to leave you feeling desperate and barely surviving. You are alone, have little ammo, and your enemies refuse to die easily.
As Isaac Clarke, you head off on an interstellar repair call only to find the crew of the disabled ship have been mutated. Isaac must travel into the bowels of the ship in order to repair it and escape the intelligent and ruthless necromorphs. These mutants will disappear and appear from the vents, play dead till you get close enough to pounce and just plain rip you apart to make sure you can't complete your mission.
The only way to defeat these monsters is to dismember enough of their limbs until they finally fall. Tense combat and a truly scary environment with some original touches make Dead Space an excellent addition to the survival horror genre.
