Dead Space makes the mission of engineering team Concordance Extraction Corporation (CEC) take a horrible turn for the worse when they arrive at the USG Ishimura (a "Planetcracker" Starship) in response to a distress signal sent to them from the ship. You play as Isaac Clarke (the engineer) and after you and your other 2 team members crash on to the suspicious vessel, you begin to suspect everything is not as it seems and something is definitely wrong, and boy is it! Suddenly a horrific creature pops out of the ventilation shaft and frightens the shit out of you, so now you must run for it, all the way down the elevator away from commander Zach Hammond and computer specialist Kendra Daniels as you get chased down a dark corridor by one of the mutated fuckers. And so your dark, scary and disgusting adventure begins.
The gameplay is all from an over-the-shoulder third-person perspective, but the game manages to seperate itself from far from other third-person games of its type. The graphics are incredibly detailed, and the atmosphere and the environment constantly give off a deep sinister edge. There is a constant rattling and tapping everywhere and you are taken so far from your comfort zone that eventually every wall fan seems lethal to you! The monster's sure do have a big case of the munchies and love to get up close and chew on Isaac, but by tapping the A/X button you can get loose and sort those bastards out (even though all they want is a hug).
The fun is not just on board the ship, as sometimes you can take the fight out in space (with gravity boots) where there are no sound effects at all all, just Isaac's deep breathing. You can jump wall to wall but you must fight quickly as otherwise you can suffocate and get lost in space. This provides an intense experience to the player, but sometimes you can't navigate so easily due to all the tension and the need to rush.
