This game offers unique play. It has a pretty good storyline that keeps your attention, but the stealth required to play the game makes it a keeper. Unlike Metal Gear, you actually loose points by being spotted, even if you make it through the mission successfully. You can opt to go through the mission again for a higher score, or you can go on to the next mission. I liked that aspect the most because the second time around (knowing where everyone is hiding and waiting for you) you get to get the drop on them! Cool beans.
