If you like the old school survival horror games this is your game and if not you should give it a try too.
The graphics are just great and i have to say that the game is very optimized, you can run it even in a low spec pc and im talking about a pc from 2002.
The environment is very well designed with a lot effects of lighs and shadows.
The sound well is a convination of penumbra and silent hill, you will offen hear voices whispering things, sounds of the ship very scaring or monsters noises and the music is just great.
One thing you find in dead space is the possibility to upgrate your weapons and gear through a system of collecting things called modules and using them, you can also buy them.
In the game you will be collecting items ammo and others kind of stuff and the good thing is that you can store your items!(Remember Resident evil chest?)
You will have space in your gear to carry some limited amount of items(Yes like Resident evil inventory) and through the upgreat system you will be able to add slots to your gear.
Your char have 2 powers that you will have to use to pass some parts of the game, like miny puzzles one is telequinesis and with the other you can slow down objects or anything you aim, you can always upgreat your powers making them to last longer or have better range.
The enemys are very well done and with your weapons you will cut them in 100 pieces, the game have a lot of gore and blood, to kill an enemy you have to cut they limbs or heads you cant kill them in any other way, you can use the parts of your enemys like weapons with the telequinesis.
I hear some players that say the camera is not good or is a little bit annoying but for me is fine is like resident evil 4.
Well the story is excelent too.
So if you like survival horror games you must buy it and if you dont you have to give it a try at least
