Dead Space does not use a traditional heads-up display; instead, all information is relayed to the player via holographic projections from Isaac's Resource Integration Gear (RIG) spacesuit and the weapons themselves. For example, a small holographic display on the weapon shows the ammunition count; also, the "health meter" indicating Isaac's condition is integrated into the suit spine. 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. However, the game still progresses in real time, so the player is in danger of being attacked while doing this.
Combat involves a mechanism called "strategic dismemberment", in which the player must cut off limbs or sections of the Necromorphs to defeat them. For example, shooting certain Necromorphs in the head will have little effect, but they can be stopped once the player removes its arms and legs. Depending on how they are wounded, Necromorphs can adopt new stances and tactics, even sprouting new limbs or giving birth to new enemies in the process.
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 (for horizontal and vertical slicing), rotary saw, a hydrazine torch (repurposed as a flamethrower), a high-energy contact beam, and a force cannon that emits powerful shock waves. A military-grade automatic rifle is also available. All weapons feature a secondary-fire mode; for example, the plasma cutter can be rotated 90 degrees for an optimal angle for more effective dismemberment of vertical limbs (such as legs on a normal bipedal humanoid). 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 Bench units, workbenches used to upgrade Isaac's suit and weapons with "power nodes".
Other than weapons, Isaac is also equipped with other tools to help him survive, solve puzzles, and combat enemies more effectively. Isaac's Stasis ability can be used to slow down enemies and objects temporarily, and a Kinesis module allows Isaac to pick up and throw items, which also allows him to impale Necromorphs. Dead Space also features vacuum and zero gravity 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.
