Charles Onyett: Did you ever see John Carpenter's The Thing? Remember all those gross tentacle monsters that bubbled and slithered all over, killing everything and generally giving Kurt Russell a hard time? That's basically the type of horror in Dead Space, except you're on a starship and the enemies are more numerous, more aggressive, and generally creepier. They break through walls charge after you, flapping and wiggling unnatural appendages and making it very clear that their only desire is to tear you to shreds. And they will. Many, many times. It's your job to target their extremities with a bunch of brutal weapons and dismember them before they can do the same to you, and by the end you can be sure several Olympic swimming pools could be filled with the blood that's spilled. It's one of the scariest games of the modern gaming era, and it's a must-have for anyone looking for a gruesomely satisfying mix of powerful Alien-esque atmosphere and Resident Evil-style gameplay with a few clever zero-gravity twists.

Nate Ahearn: I love being scared. Call me a masochist, but the feeling of sitting in a dark room with my surround sound turned up to 11 with a survival horror game in my Xbox is tough to beat in terms of overall pleasure. Dead Space was a rare breed of horror game in that it actually scared me. Its blend of Aliens-meets-Event Horizon created some eerie corridor situations with some less than attractive creatures -- a wonderfully delicious horror cocktail. Despite the lack of multiplayer and generally short single-player experience, Dead Space is still a wonderfully cinematic and engrossing story with plenty of thrills and chills to go around.
