One of the best FPS's out there.
It's a little like a James Bond style of game but with more action. It has a very good storyline that really takes you into the game's world, with some really cool gadgets.
The things that make it more Bondy then others is that you can sneak up to people and use the objects around you to help and create distractions. The enemies are really smart, for example if you run into a chime it rattles and they become alerted. The gadgets are cool too, you can get welders disguised as hair spray bottles, a bazooka disguised as a briefcase and heaps more. Its not all sneaky stuff though when alarms go off it time to bring in the heavy gear with guns like AK-47s, SMGs, shotguns and snipers. The graphics are good too with great sound affects and cool sight seeing. One thing that could be improved though is the difficulty, its very hard for people who play the first time and should be made a little easier for new comers. But over all it's a great game
