NZGamer writes: "There's much to celebrate in Killzone 2. A solid campaign, an ever-mutating multiplayer and a graphical leap for mankind. It is important however, to understand that underneath the veneer what we have is also very recognizable: this is still a game that includes token 'red barrels'. For all its guts and glory, for all its taxing, gritty fortitude, Killzone 2 adheres too strictly to the rules of its genre to send itself into the stratosphere. What will stand the test of time is its pitch perfect grasp of said genre, its wonderfully taxing, take-no-prisoners assault on your senses and your trigger finger. It is the ultimate conservative First-Person-Shooter, whether it wants to be or not. And this is why it's worth your bucks".
