Anyone who likes survival horror, such as Resident Evil... CHECK THIS GAME OUT!!! :D
This game is awesome.
It's scary, intriguing and very well produced. The graphics and sound is great, the fact that there is no HUD and that the game does not pause when checking inventory, maps etc. makes it feel very real and contributes greatly to the constant tension. Monsters will come at you when you least expect it (until you start expecting it all-the-time) and the sounds they make, in combination with the soundtrack, is guaranteed to make most people jump.
The environments in Dead Space are stunning, especially when you get a nice view outside of the ship, but even the regular corridores and diffrent areas of the ship looks superb. Enemies are sometimes not as good-looking (graphic-wise) as they could've been, but honestly, most of the time you will be too freaked out to even notice.
This game has taken the concept of Resident Evil and turned it even better. In contrast to the RE-games though, this game is a little more repetitive, but that's ok because there's a very interesting twist near the end, and the final boss fight redefines the meaning of EPIC.
If you like survival horror games, this one is your new bible. BUY IT! :D
P.S. cutting your enemies limbs off is FUN :P
