Eurogamer: "It's easy to be blinded by the sideshow with Killzone 2. Any platform exclusive is going to attract the wrong sort of attention in the current console climate, and when the game in question is the sequel to a poorly received last-gen title, the stakes are raised even higher. Sitting down to evaluate it, you can feel the clutter hovering over your shoulder. Texture maps are scrutinised for the slightest flaw, frame rates obsessed over, AI team-mates subjected to Mensa tests.
Fortunately, Killzone 2 makes it easy to ignore them. Let those with vested interests debate the pointless minutiae. For those pining for a muscular, aggressive military shooter, whose console has the biggest balls soon becomes a minor concern. It swiftly becomes apparent that Killzone 2 isn't going to be pushing beyond the boundaries of its genre. That could be taken as lack of ambition, but in context it feels more like creative focus - this is a game that polishes existing concepts to a compelling shine, rather than colouring outside the lines in search of new patterns."
