"To survive the xeno-onslaught, you must shoot the crap out of everything that moves. But the aliens in Dead Space don't die if you shoot them in the head. An effective kill requires that you first dismember the appendages-arms, legs, tentacles-of an alien before you can be sure it won't get up again. It's a unique twist on the familiar "headshot" equation and the strategy and creative aiming required adds an interesting twist.
Dead Space is a showcase piece of dark-side entertainment that rivals the marvellous designs of such games as BioShock, Gears of War, and Resident Evil 4. But be advised that it is definitely not for the queasy or the faint of heart. Still, if you can stomach its horrors, you will be rewarded with one of the best survival horror experiences ever created."
