A rare gem of a game
Having bought the game years after it's initial release and mainly because it was so cheap my expectations were... Measured. However Dead Space blew me away with it's amazingly atmospheric and often genuinely scary gameplay. The weapons are varied and a lot of fun to use and the enemies are suitably single minded and bloodthirsty - AI may be lacking but what self respecting mutant-alien-human-hybrid is going to spend it's time ducking behind crates?!
And when you're not busy blowing off limbs and suffering (extremely) gruesome deaths, the game keeps you occupied hunting down the next objective with twists and turns along the way. Can't wait for the sequel - it has a lot to live up to!
