A friend let me borrow the game and I was amazed. I requires a heck of a lot of strategy. I am still waiting for a game like this for my PS2. This is the only game that got me away from play Madden 2001. Basically you go threw a bunch of missions so you can destroy metal gear, which is a nuclear weapon. The game not only includes killing and adventure, but also tries to teach you about the nuclear weapons and power. I think getting this game for ... is a steal. If you have never played it definitely buy it and play it on normal or hard mode. It will waste the adventure to play it on easy. It took me around a month to beat, playing it about 2 hours a day. Only negative is that there is a lot of talking in the game.
