Game rules but graphics could be better!!!
The player takes the role of Isaac Clarke (named after science fiction writers Isaac Asimov and Arthur C. Clarke), an engineer who must fight his way through a stricken mining ship infested with hostile, grotesque monstrosities called Necromorphs, which are human corpses transformed and reanimated by an unknown alien organism. He also must battle a religious and a government conspiracy. The game features an 'over the shoulder' third-person perspective, similar to the gameplay in Resident Evil 5 and Gears of War.[]. The game includes a number of RPG elements. These include the use of upgrade modules, including suit and weapon upgrades. Audio, video, and text logs scattered throughout the ship reveal a great deal of the plot.
The interface of Dead Space is unique in that it does not feature a traditional head-up display. Instead, all information is relayed to the player via holographic projections and the features on the suit and the weapons themselves. For example, a small display on the weapon shows the ammo count; also, the 'health meter' that indicates Isaac's condition is integrated into the spine of Isaac's armor and ranges from red (low/critical), yellow (half), to blue (full or near-full).[6] Via floating holograms projected in front of Isaac, the player can check the current objectives and the 3D map, or access the inventory screen to manage items. Meanwhile, however, the game still progresses through time, and the player is always in danger of being attacked.[6] The only menu in which the game is not still in progress is the pause menu and the save console menu.
Combat in Dead Space becomes complicated when Necromorphs do not simply "die" after receiving a certain number of gun rounds. In fact, depending on how they are wounded, Necromorphs can adopt new stances and tactics, even sprouting new limbs or giving birth in the process. To defeat the Necromorphs, Isaac must use "strategic dismemberment," the methodical severance of specific limbs or sections of the Necromorphs. A prime example of this is when fighting the Necromorph nicknamed "Pregnant". Shooting this Necromorph in the stomach will release a swarm of small parasite-like aliens or other forms of Necromorphs, so it is preferable to carefully shoot off its appendages while leaving its stomach intact.
In keeping with Isaac's profession as an engineer rather than a soldier, the weapons in Dead Space are mostly improvised from mining tools such as a plasma cutter, rotary saw, a hydrazine torch used as a flamethrower, and a force cannon emitting powerful shock waves. However, a triple-barreled automatic military rifle is also available. All weapons feature a unique secondary-fire mode; for example, the plasma cutter can be rotated 90 degrees for an optimal angle, and the flamethrower can set fire traps. Like in many survival-horror video games, the player must scavenge for ammunition and other various items, which are found throughout the ship or dropped by Necromorphs when killed. Automated stores throughout the ship can be accessed to buy and sell items or store them for later use. Also, the player can use work benches and spend "power nodes" to upgrade Isaac's suit and weapons.
Other than weapons, Isaac is also equipped with other tools to help him survive, solve puzzles, and combat enemies more effectively. These are all contained in his suit, the RIG. Stasis can be used in the game to slow down enemies and objects temporarily, and a kinesis module allows Isaac to pick up and throw items. Dead Space also features Zero gravity and decompressed environments, and Isaac can navigate through them using his pressurized suit and magnetic boots. Isaac will eventually suffocate while in a vacuum or a toxic environment as his suit can only contain a limited amount of air, so the player is forced to proceed quickly when in these situations. Also, Isaac can jump from platform to platform in weightless enviroments. Some levels even lead out onto the surface of the ship's hull. Floating debris presents a hazard, however, and Isaac can lose his footing and simply float off into space.
