It is VERY
good. Go buy it.
It's kind of hard though. The first level is insanely easy (and short, it's to the game what the pre-title sequence is in the movies), the second one ramps up the difficulty. The exception is the Boss fights, which seem pretty easy so far (but then again I've only done two). It dumps you right into the action, in the second level, you see Bond set a timer, run out of a building as it's exploding, then jump off the building as he turns and shoots his rapelling cord. The next instant, you're in control of Bond as you rapell down an exploding building
It's third person, so you actually get to do stuff Bond would normally do, like hug a wall and peak around to aim at enemies. The driving is pretty good too, akthough you have to watch your ammo use (there's a helicopter level where I ran out of ammo during the boss fight).
There's things called "Bond Moments" where you trigger events in the level. There's one on the second level where you hit a steam valve and it kills a bunch of the thugs standing on a grate.
It really is like playing through a Bond movie. The voice talent is supurb, with Heidi Klum, Shannon Elisabeth, Judi Dench, William DaFoe, Mya, and John Cleese providing dialog. Mya sings the title song too, and while it's short, it's pretty good.
