fans of survival horrors (like Resident Evil) will no doubt be happy with Dead Space.
it's genuinely very creepy in places and will probably make players jump at least a couple of times. this aspect of the game owes to the excellent detailed graphics and the atmospheric sound effects. the storyline is engrossing and decent, even if it's basically Alien(s) meets Event Horizon.
the 'dismember limbs to kill em' aspect of the game, while seemingly quite unique from other shoot-em-ups, in reality, isnt that much different. its a nice touch, but hardly revolutionary. the weapons and equipment upgrading and shop systems adds an RPG-style element to it, giving the player a degree of flexibility in terms of what weapons and equipment they want to focus on - higher ammo capacity, power or more health?
however, the game itself is pretty linear. the game is divided into 12 stages, and once you progress to say,stage 5, you dont have the luxury of travelling back to previous stages (unless the storyline dictates it). by clicking the right thumbstick, you also get a route outlined to your next objective, which makes the game pretty easy. maybe im expecting too much fresh out of playing and completing Fallout 3, but it isnt very demanding on players to work out exactly where to go or what to do. it may be a survival horror as opposed to an RPG, but either way i'd personally like more of a challenge from a game.
the zero-gravity areas are a nice touch, and adds something new and different to the genre and the whole concept of problem solving.
the weapons are all decent and well-designed. as stated above, its nice to be able to choose how weapons are developed while many of the enemies are truly disgusting and detailed.
given that the game is set on a spaceship, the levels arent as repetitive as you'd initially imagine. there are various different and distinctive areas throughout the game from a greenhouse to a mining facility to the usual claustrophobic corridors of the ship main and a visit to the wrecked planet colony.
overall, Dead Space is a worthy buy. it has its flaws, such as being too linear and while its also quite short (i completed it in 2 days).replay value is restricted and depends on whether you want to go through it again to fully upgrade all your weapons and equipment. in terms of story, you do not have the freedom to dictate where the story goes at all so in this respect, there is little to replay. like a rollarcoaster ride it may be a shortand you only go where the track leads, but its a really engaging one, which at times is genuinely scary and a fair bit of fun can be had.
