This game was a great purchase here on gog. A little hesitant at first because I remember owning this on ps2 as a kid and struggling with it a bit - I was better suited for the run and gun type of shooter back then. But, I picked this up on sale a few months back and it was definitely worth it - even not on sale this is a great deal. Even though the story is a little cliche and some of the dialogue is as well, the gameplay is just perfect. It allows for a real challenge, while offering a great satisfaction when you figure out the right way to approach a situation. Tactics are just as important here as your M16. Even after completing the game, I still go back and play different maps to attempt different ways to complete my mission. Go ahead and get this if you're on the fence.
