Who has played this fantastic video game for ps2?? I just purchased it and I've only gotten a bit of game time but I've played enough to form my opinion. This game seems like it'll be a challenge, and it has really good gameplay. The melee weapons are cool, and gun freedom is amazing IMO. You do have to earn difficulty levels as you progress through the game, starting at normal. I plan on trying it out on hard just as every game I play. What do you guys think??
