The story starts with the player taking on the role of Isaac Clarke an engineer aboard the star ship Kellion. Your destination is the damage stricken USG Ishimura. Upon docking with the Ishmura, the Kelion takes damage forcing your team to board the mining ship.
Once aboard you and your team quickly find out nothing is what it seems.
From mad scientists to horrific creatures, this game has a good story and a creative use of the game environment. Although the game does have some minor problems with large monsters and small corridors, the general game play works very well.
You will get to experience zero g, where you can leap from wall to wall and even wall to most other surfaces and oxygen-less environments, where it feels like time is standing still..
This game has an interesting array of weapons. Unlike your normal shotgun or automatic, Dead Space gives you access to weapons that would seem to be more closely related to engineering tools. Infact there are six weapons in total, ranging from the Plasma Cutter to the Supercollider Contact Beam, each offer its own unique way to dismember your enemy limb by limb. These mining tools will help you survive the horror.
One of the other parts of the games has a flavour similar to System Shock 2, where the player can use workbenches to make upgrades to weapons and the players rig (Space suit), using power nodes to make the connections to improve HP, Damage, etc. This sort of node system is similar to that also found in Bioshock.
This game also offer a unique HUD (Heads Up Display), rather then having bars or information running round the edges of the screen, the player himself, or at least the rig shows the players health (running down spin), power (to the right) and oxygen (displayed as required).
Ammo is also displayed on the weapon themselves making for a truly full screen horror.
All in the game is very good, if a little slow at times.
