This game plays similarly to Resident Evil 4 which is a good thing. The story is compelling. The environments contribute to an unrelenting chill-factor. I liked the way the A.I. was programmed to react to some of your attacks to make you think a bit more about how to go about dispatching an enemy. The weapons and the ability to upgrade them along with your abilities added even more dimension to the game. This game is one of the best survival horror games out there. Think the matrix meets resident evil in terms of the horror sci-fi-esque story line.
