Visually and from an audio point of view, the game is spectacular. Nice textures throughout. Great wrap- around sound. The character art style was not 100 percent to my personal liking, but it all was executed well with great animation. The soundtrack that accompanies the action is terrific with good rock beats and some 1960s-spy-movie-styled tunes. Voice acting is not the absolute best, but is more than just serviceable. Too bad the story did not have more meat to it.

So, is Perfect Dark Zero the killer app that will sell millions of Xbox 360s like Halo sold the original Xbox? Not likely. While the game is well executed and will offer hundreds of hours of gameplay through campaign replay and multiplayer, it is just not quite as compelling an experience as the Halo games were. (Actually I should say "are." The Halo Link gaming group I play with, The Coagulation Cabal, still gets together once a month to play and Halo 2 consistently tops the charts for Live play.) But in the end it is unfair to compare PDZ and Halo. If your primary purpose for buying the Xbox 360 was to play online, this is definitely the game to pick up from the launch title assortment. Standing on its own, without comparing it to a genuine phenomena, Perfect Dark Zero well earns its "A" rating.
