Dead Space draws a lot of inspiration from Resident Evil 4, but it's considerably scarier. The incredibly dark atmosphere and grotesque enemies will keep you on edge, but it's the impeccable sound design that REALLY brings it all together; not to mention the incredible multitude of ways you can die in this game. The Limb Dismemberment system REALLY keeps things interesting and is such a stand-out feature I'm surprised other games haven't tried to implement it in this manner. This is such a great horror game. Any horror fan should play this.
