It has been along time since I have played that game and I don't remember much of it, but I do remember liking it alot. The way they do the end credits in that game is probably the best I have ever seen in a game.
Just remember its an older game so don't expect for it to live up to 2011 standards. Keeping that in mind there is multiple ways to do things and a good mix of stealth and action. If you like games focused on sneaking around, casing your target and doing slick kills then it won't disappoint. There are other ways to do it but that is how I played through it. For a rental you really can't go wrong.
