Square-Go:
"The story ain't bad. It's somewhat linear and more than a little obvious, but there are interesting characters, a dash of conspiracy, and a hell of a lot of paranoia. The blend is a wonderful, engaging narrative that draws you in while making you despise every terrifying step. In addition, there's an inventory screen and an upgrade system which adds a little strategy to the whole nasty affair.
If Dead Space has but one fault: it's that all of this have been done before. Every single element is blatantly ripped off from some other hugely successful movie and game. If you're a big sci-fi or horror fan, chances are you'll find a lot here oddly familiar. It's been a very long time since a game so immersive, playable and beautiful managed to get away with being so unoriginal.
Do not mistake me: Dead Space is astounding, wonderfully unifying atmosphere and action. Nevertheless, the fact that every single great idea was transparently cannibalised from other cult-driven series restricts its splendour. Play, enjoy. Just don't expect a life changing experience."
