Summary: Get this one only if you either love stealth-based play and need a break from Splinter Cell/Metal Gear or are looking for a discount item. Movement control is clunky, especially since you have to use the the "look" command in specific (VERY specific) onscreen hotspots to perform anything but the most basic of actions. Has some serious glitch issues as well (eg, I died during a boss fight, yet the cinematic showing the boss' death played and I went to the next level).
Summary: I bought this game because of the picture on the box - well, forget about seeing that "feature" in the game. You get a rather primitively animated character. So how's the gameplay? Not too great. You'll spend a lot of time standing around waiting for stuff to happen. Wait...and wait and wait and wait...for some guy to walk down a hallway so you can sneak behind him. Wait for some guy to show up so you can shoot him.
Summary: This game is tough. You have to sneak around steathily because if you get caught it is impossible. The plot is terrible and the voices are as bad as castlevania. It's dumb that the gaurds like can't see you in the dark if you are crouching down and right behind them stealing something from his pocket. Good level design. Graphics aren't really jaw droping.
