Good, but could be better!
Graphics: Very good graphics. It reminds me of Half Life 2 graphics. It has some very interesting elements such as the grenade explosions. The "hospital" cut scenes are unique, too!
Sound: Sound was good. Some of the guns sound a bit weak, while others are HUGE. Environmental sounds are excellent, though!
Overall, I was very satisfied with this game. But, it could have gone more in depth. You find yourself fighting the same 3 or 4 enemies through out the WHOLE game.
