Dead space is one of the the best horror games out there. Set after the movie Dead Space Downfall you play as Issac Clarke, an engineer in a rescue/salvage party tasked with discovering what happened on the planet cracking space ship Ishimura. You feel so alone and vulnerable as you walk down dark blood stained corridors with the slightest noise or flickering light making you jump in your seat. It's not long before you discover what happened to the crew, and then the salvage operation turns in to a fight for survival. The game has a range of unique weapons ranging from flamethrowers, mines, saws, and of course plasma riffles. Weapons and suits can be upgraded to do more damage, hold more ammo, reload faster and so on. The zero gravity areas in Dead Space are nothing short of brilliant. My only gripe with this game is walking feels very clunky and slow, possibly trying to simulate the space suit he's wearing, but annoying nonetheless.
