This game is almost perfect. The graphics are amazing and the little things like your clothes being soaked when you come out of the water makes it enen more believable. Game play is great and there are enough ways of atacking your enemy that it stays fun. There is an interesting storyline that will make you actually want to watch the cut-scenes and keeps you guessing throughout the game. In the menu there is a bonuses option that shows you the treasures you have found, medals you have earned (for completing specific tasks, and unlockable content that you earn by winning the medals). There are "Hidden Medals" in the game that turn out to be get a certain # of kills with each gun or completing the game on different difficulty levels. The only problem with this game is that it isn't long enough. It takes about 10 hrs. and that seems fine untill you play and really get into, then it flies by like nothing. THIS IS A MUST BUY FOR PS3 OWNERS!
