It's not bad. It's a very polished game. The quality shines through but in gameplay design it's veering too much towards Splinter Cell. I really hate the choices they made toward introducing cover, making levels that want you as the player to use this cover and the changes introduced to the disguise system.
I will say this, Blood Money is overall the much better game, and I think I can safely say that. Especially in terms of level design, and the amount of freedom you have. Not to mention the soundtrack and even the story. The story is fucking stupid from what I've seen of it so far, and the side characters annoying as hell. I love the mission descriptions done by 47 himself but they bury it in an optional ( press select ) menu.
From the beginning of the game, 47 almost has nothing to work with. As you can't select weapons before you go on a mission, I havent been able to use stuff like syringes or many other trademark 47 equipment. Yes you can carry disposable items like bottles, wrenches, pipes and you can even find a syringe. But you can only carry one disposable item so you can't keep the syringe. Also, I know I played on hard but how can a goon with the same disguise as me know I'm not part of his crew from waaaay across a room? Shit doesnt make sense.
